iOS - How to set a UISwitch programmatically

UISwitches have a property called "on" that should be set.

Are you talking about an iOS app or a mobile web site?

If you are using a UISwitch, then as seen in the developer API, the task setOn: animated: should do the trick.

- (void)setOn:(BOOL)on animated:(BOOL)animated

So to set the switch ON in your program, you would use:

Objective-C

[switchName setOn:YES animated:YES];

Swift

switchName.setOn(true, animated: true)
