Disable & Enable Idle Timer in iOS SDK

By default, the idle timer will dim the screen after a period of non use and then turn the power to the screen off. You may need to disable idle timer on a specific app such as a Flash light app or location-based app.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
…
}

Add the following line:
[application setIdleTimerDisabled:YES];

- (void)applicationWillTerminate:(UIApplication *)application {
…
}

Add the following line to re-enable the idle timer:
[application setIdleTimerDisabled:NO];

This won’t work on the Simulator but it definitely works on device.
