Creating programmatically a switch (UISwitch)

UISwitch is one of the best framework of UIKit. To create it programmatically, code:

UISwitch *mySwitch = [[UISwitch alloc] initWithFrame:CGRectMake(50, 100, 0, 0)];

Above range allocates an UISwitch and models its shape. UISwitch has resolved measurements (about 95 px extensive, 27px high), so you have to set the harmonizes for top-left part. Size and size are ignored, you can not create swap lesser or larger by modifying the shape.

To add it to your perspective you should use this code:

[self.view addSubview:mySwitch];

Be standard swap is set to Off. You are able to modify it’s condition programmaticaly using setOn method:

[mySwitch setOn:YES animated:YES];

To swap it rear again to Off use:

[mySwitch setOn:NO animated:YES];

In both above situations UISwitch changes it condition with movement (animated:YES), use animated:NO to modify condition without movement.

To have a look at UISwitch present condition use on residence, example:

if (mySwitch.on) NSLog(@"switch state: on");
else NSLog(@"switch state: off");

To avoid modifying the UISwitch condition set the empowered residence to NO:

mySwitch.enabled = NO; // or YES to reenable it

As I said before UISwitch is very easy framework – any measures – holding it causes UISwitch to modify it’s condition, so to telephone any strategy by modifying the UISwitch you have to add a focus on for ValueChanged event:

[mySwitch addTarget:self action:@selector(myMethod) forControlEvents:UIControlEventValueChanged];

or

[mySwitch addTarget:self action:@selector(myMethod:) forControlEvents:UIControlEventValueChanged];

If you need a id to mySwitch item.

Key information to prevent Apple’s iOS app rejection

An app concept or products app requires much of cash financial commitment to get into app world everyday living. The significant problem to it’s achievements could be Apple’s evaluation procedure. There can be several factors for Apple’s rejections for your app. With our excellent understanding of iOS applications progression since the day The apple company released their SDK, we are able to obtain useful ideas into Apple’s evaluation procedure.

This will help:

1. Designers to spend less their some time to initiatives.

2. Let you strategy for a better buyer which is the key objective behind all the app keep recommendations.

There are few key details which every iPhone/iPad creator should know when producing an app for The apple company gadgets.

Key things to prevent Apple’s app rejection:

1. Bugs/Crashes- The most typical objective for any app to get refused are cold and consistent failures. Make sure you analyze it on several gadgets, different OS versions and particularly under various system circumstances. Peer-to-peer reviews/testing done by developers would certainly help. If your app failures or does not answer during the app evaluation by Apple’s examining group then it will definitely be refused.

2. Value Download- You cannot create an app that downloads available and completes concept that was not existing in the app deal presented to The apple company.

3. Identical Icons- The app keep 512×512 symbol should be same as the app’s 57×57 symbol. Even though there is no such immediate concept in contract/agreement with The apple company, its their keep and they result in the guidelines for opinions. If your app’s symbol on phone and app keep symbol do not go with, The apple company will condition having un-matching designs to decline the app.

4. Network Connectivity- You must advise the customer if system is out of stock. Just having the rotating fast paced symbol existing and a concept saying “trying to connect” is against the recommendations. Appropriate concept is required at all the displays to express clear concept if system is not available after certain time period. Many developers put their connection assessments on Apple’s Reachability concept, which is using that example concept for the incorrect objective. If you need to get information from a particular hosting server, then try to obtain some information from that website.

5. “Free+Paid” apps- The apple company revealed to few developers that app may get refused, if it contains aesthetically incapable keys, driving the customer to update for the complete edition or showing the price of complete edition in the Free edition. So, iPhone developers must make sure that they adhere to all the guidelines.

6. Constant Option Images- If an iPhone creator wants to use Apple’s existing picture for his button then see that features resemble because you can use a normal button in a non-standard way if your app is offering a “immersive environment” so it is better to make your own button. If there are any versions with operate then again The apple company might decline the app.

It is always recommended for an iPhone creator to use their own customized keys in the app

7. iOS edition support- If you strategy on posting and app which operates with 3.0 and greater versions, you should be sure that it operates completely on all the versions from the iOS 3.0 to the most existing edition. The apple company will analyze it with the newest edition to see the prospective of the app but if the app isn't able to confirm itself The apple company will definitely refused your app.

8. Dealings outside The App Store-

Apple do not allow developers to perform any transaction/business outside the app keep. In App buys are the suggested way to put into practice these purchase. Latest statement to allow outside transaction purchase with certain reduction and Apple’s amount take from cash for the same is more difficult and would take more a chance to negotiate down in strategic enterprise strategy of applications purchase.

9. Personal API:s

Apple stringently decline applications which are employing plans using Personal APIs. The apple company has plans that can check your app requirements for offenses. If you want to prevent app denial from app keep make sure you study the creator recommendations properly before employing any API noted private by The apple company.

10. Popovers-

It is definitely not suggested to release one popover from within another popover. The iPad People User interface Guidelines clearly provides this information that only one popover factor should be found on-screen each time.

There can be many more factors behind Apple’s denial of any iOS app. However, the collection provides very apparent ones.

Objective C Protocol

“A strategy is simply a collection of strategy conditions, separate to a training description. (In Coffee, program is symbolic of strategy.)”

Protocols assert techniques that can be integrated by any training. Methods are useful in at least three situations:

    To assert techniques that others are required to implement
    To assert the program to an item while covering its class
    To take parallels among sessions that are not hierarchically related

Classes in not relevant offices of the monetary gift structure might be searched as well because they comply with the same strategy.

Protocols collection techniques that are (or may be) integrated somewhere, but the personality of the training that tools them is not of attention. What is of attention is whether or not a particular training shapes to the protocol—whether it has implementations of the techniques the strategy reports. Thus items can be arranged into kinds not just on the foundation parallels as a result of getting from the same training, but also on the foundation their likeness in contouring to the same strategy.

Cocoa has relaxed protocols as well as proper protocols. An relaxed strategy is a classification on the NSObject training, thus making any item a prospective implementer of any strategy in the classification (see “Categories”). The techniques in an relaxed strategy can be precisely integrated. Informal protocols are part of the rendering of the delegation process in Mac OS X (see “Delegation”).

Formal protocols unconditionally need the contouring training to put into practice all announced techniques. However, they can level individual techniques or categories of techniques with the @optional information, and the contouring training may choose to put into practice those. They are also fragile; once you determine a strategy and make it available to other sessions, upcoming changes to it (except for extra optionally available methods) can separate those sessions.e

Windows SkyDrive App Occurs for iPhone

Enthusiasm has designed a SkyDrive app for the iPhone, again showing the changeable desire to make application for its competing.

Although Enthusiasm a lot wants its Microsoft windows Cellphone foundation to eat away at the visitors for the iPhone, the company knows Apple’s hold over the mobile phone market. Accordingly, it has published new cellular programs for its SkyDrive impair storage on Microsoft windows Cellphone and the iPhone.

“In addition to their OneNote laptops, iPhone customers can now access all of their information in SkyDrive, make information, remove information, and discuss links to information and information directly using the Mail app,” Robert Torres, group program administrator for SkyDrive Devices and Running, authored in a Dec. 13 publishing on The Microsoft windows Blog.

Other app features include the ability to look at the entire SkyDrive, discuss any file or file with one or more people, and make new information. Customers can also arrange their information and information according to personal choices.

Microsoft has designed other programs for Apple’s cellular items, such as Ask and OneNote. Despite their nasty competition in cellular systems and other classes, Enthusiasm has hard ongoing to build application for the various Apple company platforms: a wise move, considering the lasting popularity of the latter.

Rumors have produced that Enthusiasm is planning on bringing a tablet-friendly edition of Workplace to the iPad sometime in 2012, at least according to un named sources reported recently by The Daily. That magazine added that a new edition of Workplace for Mac OS X Lion is also in development for launch sometime in 2012. Presumably, Enthusiasm is also preparing a touch-optimized edition of Workplace for its own future Microsoft windows 8 pills.

Both Apple company and Enthusiasm are dealing with Managing system for control of the cell phone space, although Enthusiasm seems to have made more success in injuring their good challenger. Even as Microsoft’s Microsoft windows Cellphone scrambles for footing among mobile phone users, the changeable legal team has moving a increasing list of Google Managing system system producers into paying royalties for their items. Enthusiasm claims that Managing system breaks many of its patents.

Android royalties or no, Enthusiasm will need to face down the increasing host of Managing system tablets—and the iPad—with its Microsoft windows 8 pills. The future operating body's program is bifurcated into two individual environments: one filled with vibrant flooring attached to programs, really ideal for pills, with a more traditional esteem computer that should attract power PC users. It seems a matter of course that Enthusiasm will develop programs of its more popular items for its main foundation.

The apple company shows iPhone 4S with A5 nick, Siri, fast system speeds

The apple company retracted the layer on the next iPhone on Wednesday, and it both was and was not what individuals were anticipating. The iPhone 4S is Apple’s latest mobile phone, and while it holds a stunning likeness to its forerunner, that simple outside conceals a monster.

The new iPhone 4s has the same actual measurements as the iPhone 4, and the same glass-and-steel development. That is not really a large issue; Apple’s business style grinds still create this the best looking, best sensation cellphone that you can buy. And now the good looks are coordinated up by industry-leading inner specifications, by means of a dual-core A5 model that provides up to two periods the efficiency of the iPhone 4. In addition, there's a dual-core style model under the cover, offering up to 7x the efficiency for game playing.

The iPhone 4S also has up to 8 a long time of talk-time, as well as a new aerial program that can swap between available antennas to come up with a highest possible efficiency of 14.4 Megabyte per second down. That is on par with real-world 4G, statements The apple company. It’s also a community cellphone, so it operates with both CDMA and GSM expectations.

A new digicam increases the iPhone 4S’s photog charm, with a bigger 8-megapixel indicator and a highest possible image result good high quality of 3264 x 2448 good quality and better evening picture-taking. It does this with a CMOS behind lighted indicator, and 1/3 quicker shutter rate. When in comparison to most factor and limbs, it should be able to have up well, with a f/2.4 aperture and high-end IR narrow for better reliability. Complete face-detection and auto-white stability are also now possible.

Video documenting with the iPhone 4S is now able of 1080p HD good quality take, with real-time movie photo stablizing and disturbance decrease. The iPhone 4S can also do AirPlay Replicating over Wi-Fi if you have an The apple company TV, or via an HDMI adaptor if you do not over a sent network.

Finally, Siri technical (which The apple company purchased last year) really did create it into the new iPhone, as rumored. But it is certainly not known as Assistant; it’s known as Siri. The concept is that you can just discuss guidelines to your cellphone, or ask it to do elements and it will be able to comprehend you. For example, on factor, The apple company demoed asking it what the elements is like, and the cellphone viewed a climate prediction. Siri can also do elements like set your security, tell you period in another town, and offer eating place suggestions finish with purchased scores, all in reaction to requires or concerns reported in normal terminology. Siri can even recognize individuals according to their connection to you. For example, Siri realized who Scott Forstall’s spouse was on factor during the demonstration.

The Siri technical has barbs in Wolfram Leader, Wikipedia and many other applications, too. Looks like it really could possibly create for some amazing lazy-web Q&A. The apple company changed discovering today!

Another new function for the iPhone 4S is speech-to-text, which also operates through Siri. It’s available anywhere there can be an on-screen key pad in iOS on the iPhone 4S, and allows you influence textual content for admittance. It roll-outs with assistance for Language, France and In german, and begins as a try out. More dialects will be included later on.

How to set-up email on your iPhone and email settings tips

Study: Apple’s iPhone, iPad profile for 90 % of cellular purchases

If people are buying through cellular on the internet full price site, they are most likely doing so on The apple company gadgets, according to a new report this week from full price research firm RichRelevance. iPads and iPhones included over 92 % of on the internet full price sales not via a esteem computer system happening in Nov, according to the study.

That’s up from 88 % the last time RichRelevance in May, and it easily defeat out Operating system and other contending cellular systems. Consumers on The apple company gadgets were also willing to spend more, with a typical order value of $123 vs. Android’s $101, and $87 from those searching from traditional esteem computer systems. RichRelevance used data from 3.4 million on the internet searching periods between May and Nov at U.S. suppliers including area of expertise stores to major e-commerce sites.

Mobile searching is still a family member drop in the container compared to its esteem computer associate, with just 3.74 % of total on the internet full price dollars spent in the U.S., but that number is growing. Thanks mainly to the success of The apple company gadgets, cellular web searching has bending in eight months, and RichRelevance CEO Mark Selinger says the trend will only increase. Key to being a aspect of that growth for suppliers, Selinger indicates, is “ensuring a easy practical knowledge across the interaction of system, perspective and consumer conduct.”

Mobile gadgets seem to be most used for searching at times when users don’t essentially have immediate access to other types of processing components. For example, RichRelevance found that during Christmas, 24 % of customers visiting full price internet sites were on cellular phones, the highest share between Nov and Nov. On saturdays and sundays traffic rises, too, up to 17 % from a typical of 14 % during the period assessed.

If there can be any key downside here for Apple’s competition, it’s that the surfing around practical knowledge is key to cellular business. Apple’s iPhone still offers the most true-to-web making of non-mobile internet sites of any mobile phone, in my opinion, which means that even if internet sites are slow to custom their practical knowledge to small displays, shoppers can still have a relatively simple searching practical knowledge. It might also just be the case that the class of The apple company cellular phone buyers runs them toward cellular searching anyway, since they tend to have a lot of non reusable income and be more aware of advertising.

The Sanction provides weather resistant security for your laptop

Objective Workshop’s $180 The Sanction is a notebook computer bag that is ready to take a defeating. This backpack—nay, rucksack—has a as well as development and is developed with a complete everyday needs in mind. As long as you are not enthusiastic about providing every pen and memory stick in its own little wallet, this is a strong bag that can take your day-to-day go and the components in pace.

The Sanction is a high rucksack with a lot of individual areas of various size. Two of the three major areas, each of which operates the complete size of the bag, have open clothes that are covered by the bag’s major flap. These two areas each have more than enough room to keep a couple guides and a explained up hoodie or water cover. The third major area, able of flexible a 15-inch MacBook Pro, is covered by a as well as zip, as are two additional lesser areas on the entrance of the bag. A third little area on the entrance of the bag, near the end, is properly secured with a velcro flap, but its beginning is restrained to prevent the components from leaks in.

The Sanction gets a lot of elements right, especially when it comes to little information and development develop. Its high design provides a lot of storage space space without transforming you into the Hunchback of the Commuter Practice, and at only 2.6 weight when clear, the bag itself will not think about you down. However, I experience Objective Working area skimped when it comes to support, a key factor of any notebook computer or computer bag. The notebook computer notebook or computer area (the one at the very rear again of the bag that is covered with a as well as zipper) has good support against your rear again, but the other walls, experiencing the relax of the bag and the end of the package, has little—during my examining, I just didn't experience assured that my MacBook was covered against the standard lumps and bruises of driving. Placing your MacBook in its own support sleeve eliminates the problem, but I’d desire that Objective Working area provided a little more built-in security.

The Sanction is also different from most of your notebook computer or computer luggage I’ve seen in that its lesser areas do not have the standard range of purses and fleshlight sleeves for splitting elements such as pencils, display pushes, recognition, important factors, and cables and wires. Luckily, there are two of these little areas so you do not have to throw all your figurine into one big get bag. One wallet is higher up on the entrance of the bag and covered by both a as well as zip and the major flap, while these other wallet is lower on the bag and more available since it’s covered by its own Velcro flap.

Overall I like this bag, though I’m still a bit dissatisfied by the support concern. That aside, luggage developed to hold up against the components this well are unusual, and as a commuter in Chicago, illinois, it’s hard to prevent getting found out in the components. The Sanction’s top-notch development and weatherproofing make me much less worried about holding out in the standard weather.

David Chartier is a Herald for 1Password, the wrangler behind the Small Things in Technical, and forever in search of the perfect notebook computer notebook or computer bag.

Flurry: Greatest Addressable Areas For Mobile Designers In 2012 Include Indian, The far east, Asia & U.S.

Mobile analytics firm Flurry is closing out the year with a look into the forthcoming shift in mobile installed bases expected in 2012. Using data from the firm’s dataset of over 140,000 apps running worldwide, it was able to calculate smartphone penetration in established markets like U.S. and Europe. Then, using additional data from the IMF in combination with Flurry’s own data, the firm was able to then determine which countries represented the top market opportunities for mobile app developers.

Not surprisingly, China and India made the list. But so did the U.S.

To start, Flurry looked at a snapshot of apps running across its user base over the past 30 days in order to rank the current addressable market. The U.S. led the way, with an installed base of 109 million out of 264 million (41%). Flurry notes that 264 million is about half of what Apple and Google say they’ve activated – something that can be accounted for by old device replacement.

China (#2) and South Korea (#4) appeared in the top five, ranking above Japan (#5), France (#6) and Germany (#7). The U.K. is #2.

Next, Flurry wanted to determine which markets hold the most future promise. It used the adult population counts from the IMF, then adjusted the numbers based on the size of the middle class in each country using a study by Miller-McCune. Flurry then estimated the size of the upper class for each country, as those folks could also afford a smartphone. This way, China, India and Brazil would not be over-represented in the estimations just because they have large populations.

And yet, they did make a showing. China has 122 million users who could afford an iPhone or Android. The U.S. has 91 million, India 75 million, Japan 65 million and Brazil 34 million.

In the final bit of analysis, Flurry wanted to determine the world’s largest addressable markets, regardless of penetration. For starters, it looked at current market maturity (the measure of how penetrated smartphone devices are among a country’s addressable audience.)  The U.S., with the largest light blue circle in the graph below, has the largest total addressable audience (TAM) at 200 million. Sweden is the most mature country with 3.2 million of 5 million (66%) addressable consumers already using iOS and Android devices.  France, 10th in maturity, has 9.6 million of 34 million (28%) consumers using iOS and Android devices.

In looking at the future addressable markets, Flurry found that even though India’s total population is not far behind China’s, its total addressable market is. Meanwhile Japan, the world’s fourth largest market, has a lot of upside given light penetration of iOS and Android devices against its large, addressable market, says Flurry.

Using this method, the top 10 addressable markets are the U.S., China, Japan, India, Germany, Brazil, Italy, France, the U.K. and Russia.

Apple's requirements for the position include a bachelor of science in computer science with 5 or more years of experience. The applicant must also have strong object-oriented programming and design skills, as well as experience with Cocoa and the iPhone software development kit.

One anticipated addition that could be folded in to Apple's iCloud suite could be a proprietary mapping service from Apple.

Whatever the purpose, a new The apple company ad indicates that the excellent white-bearded trust has determined to depend on Siri for all of his most demanding needs this Xmas.

Will it be freezing in Cleveland today, he like a charm. It's always freezing in Cleveland. Cleveland prevails to make sure that around the world is sensible out. Does he really need Siri to tell him that?

Apple organization is the Zeitgeist Company

The release of the iPad last night put an exclamation level on an extremely apparent point: Apple company is the company that has caught the cultural zeitgeist. The large boasting major up to the occurrence - seemingly obtained in a groundswell with very little attempt on Apple's part - reveals that they really are the "It" company right now.

Not so long ago, The search engines believed that location. The amount of media ink (literal or virtual) that The search engines has been able to make every individual day for the last several years is just surprising - it is not unusual to see two or three content on the same day about some element of Google enterprise, whether it be products or services or another tale about the Googleplex's free food. No other company, spend less perhaps Our country's political election strategy, can state such a cover of protection on such a regular time frame.

But the honeymoon vacation is over and we are in the process of a light backlash against The search engines, and as well Apple's cultural and economical inventory has been ascending. No-one recognizes them as just a machine of over-priced market items for designery kinds nowadays. They are truly a typical audience mass-culture company that, while centered mostly on technology, variations into so many other places of our existence simply because the limitations between computer systems, electronic products, media, marketing marketing and sales communications and self confidence have all blurry so thoroughly.

Looking back over the generations, we can see a sequence of organizations that have maintained to go beyond being just effective organizations and have caught something unique in the lifestyle. GM perhaps epitomized this in the 50's and 1950's, summarized by the well-known expression "What's excellent for General Engines is excellent for the country". GM assisted appearance the cosmetic and cultural plan in a way that attained far beyond the vehicle region.

IBM perhaps used this location in the Seventies, and Enthusiasm in the overdue Eighties and beginning 1990's, to be outdated by The search engines at the convert of the century. But none of the technical organizations besides Apple company have quite been able to win spirits in the same way GM did.

But one thing that all these organizations have in typical is powerful management who are not just excellent enterprise thinkers but are also effective in the fresh mushrooms of service. Think of Hd Earl at GM, Johnson Watson Jr. at IBM, Expenses Entrance at Enthusiasm, Sergey/Larry/Eric at The search engines, and of course Bob Work at Apple company. These men all acknowledged that there is a clear association between a organization's techniques and information of the items they carry to market. Neglecting the latter is a excellent way to scuttle the former.

The iPad is but the newest outcome of the palm of Bob (with help from a large group of people of course). The apparent convenience with which boasting seemed around it is actually no accident: Apple company has used large volumes of work over the years to develop a track record around its items and company, and that economical commitment decision is now spending off in scoops. Work himself is well utilized into the cultural zeitgeist, he transactions that to Apple's items and techniques, and in convert the company comes to indicate and even guide the zeitgeist.

It's not miracle, but it is challenging to do. Very challenging. If historical past is any clue, there is space for only one such company each a chance to carry this pre-eminent location, and their amount of time in the sun is short-lived. Apple's effective ability will come to an end, but at the same time they are entitled to all the credit they get.

NSExpression Example

The relatively new NSExpression training is very highly effective, yet not really used very often. Aspect of that is that it's not very well reported. Although the API records for NSExpression is pretty well specific, the outlined "companion guide" (Introduction to Predicates Programming) has very little details about how to actually use NSExpression.

NSExpression is deserving of to be better reported, because it provides to predicate computer encoding (including Primary Data), a lot of functions from the relational details source community that individuals often grumble are losing, like unioning, intersecting, and subtracting resultsets and accomplishing mixture functions without launching maintained physical objects or problems into recollection space.

The aggregates features is especially essential on iOS given the restricted recollection space on most iOS gadgets. If you've got a big dataset, and you want to get a matter of physical objects, or determine a typical or sum for one of the features, you really don't want to have to take the complete dataset into recollection space. Even if they're just problems, they're going to eat up recollection space you don't need to use because the hidden SQLite prolonged keep can determine that products out without the subject cost.

I don't have a chance to do a complete NSExpression article, but I imagined it at least truly worth publishing a classification on NSManagedObject that allows you take benefits of some of its more useful functions.

With this classification, to get a sum of the credit bar on business Foo, you would do this:

I don't have time to do a full NSExpression tutorial, but I thought it at least worth posting a category on NSManagedObject that lets you take advantage of some of its more useful features.

With this category, to get a sum of the attribute bar on entity Foo, you would do this:

NSNumber *fooSum = [Foo aggregateOperation:@"sum:" onAttribute:@"bar" withPredicate:nil inManagedObjectContext:context];

This will calculate it for you using the database features, NOT by loading all the managed objects into memory. Much more memory and processor efficient than doing it manually.

Cheers. Category follows:
