title: UIApplicationExitsOnSuspend and screen refresh
body: <p>I have an app that has the UIApplicationExitsOnSuspend info list property set to TRUE.
  And now I am noticing a curious issue.
  I start up the app and let it run on my phone and do not touch my phone. Eventually the phone screen goes dark and the phone goes into standby mode. When I wake the phone up, what I see is a screenshot of the last screen displayed on the app. (This seems according to spec, since the Apple documentation says that in the process of moving an app to the background, ios takes a picture of the app and uses that for transitions when the app comes back to life). If I double click on the home button to see running apps, I do not see an instance of the app running. (again, working as intended since UIApplicationExitsOnSuspend is set to true).</p>
  
  <p>My question is, how do I make sure that when the phone wakes up, it comes back to the default home screen and not the picture of the app ? Clearly the app is not running on waking up, so there is nothing I can do from within the app that will refresh the screen. I could try to exit when the app is going to background, but then apple guidelines say, never exit programatically!!.</p>
  
  <p>Any ideas ?</p>
