You use the UISwitch class to create and manage the On/Off buttons you see, for example, in the preferences (Settings) for such services as Airplane Mode. These objects are known as switches.
The UISwitch class declares a property and a method to control its on/off state. When the user manipulates the switch control ("flips" it) a UIControlEventValueChanged event is generated, which results in the control (if properly configured) sending an action message.
You can customize the appearance of the switch by changing the color used to tint the switch when it is in the on position.
In iOS 5 and iOS 6 you can set some properties that gives you even more possibilities of customisation.
