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.
