title: Switch Off iPhone Screen
body: <p>I am looking for a way to turn off the iPhone screen without the iPhone going to sleep. I don't really mind if turning the screen off is against apple rules. Would setting window alpha to 0 do the trick? Is there maybe some sort of boolean value I can change?</p>
  
  <p>If anyone has an ideas they would be much appreciated.</p>
  
  <p>Many thanks,</p>
