title: User terminates app forcefully: Registering this event
body: <p>In my app I use background services so the method <code>applicationWillTerminate:</code> will not get called when the user terminated the app. Instead the method <code>applicationDidEnterBackground:</code> gets called when the user pushed the app into to background and when the user terminates the app completely. </p>
  
  <p>The problem I am having is that I need to be able to distinguish between when the user has pushed the app into the background and when he actually quits the app because I have different code that needs to be fired for both events.</p>
  
  <p>Is this possible in my case?</p>
