Stopping the iPhone going to sleep
So, my game just uses the tilt sensors to move around and yet after a few seconds the iPhone would dim the screen causing the user to tap the screen to bring it back to life. This was annoying and it took me a while to discover how to stop it. So, if you are having the same issues then place the following line in your app delegate:
application.idleTimerDisabled = YES;
Seems simple now doesn’t it
