title: Is there a method if application was closed in multitasking?
body: <p>Is there a method like: wasTerminated or something like that? I want to display the user an alertsheet, if he has completely closed the app from multitasking. At the moment I have implemented my code in the <code>DidEnterBackround</code>, but is there another way to fix this? That would be very useful for me.</p>
  
  <p>Sorry I'm a newbie and I didn't find a solution on the net.</p>
  
  <p>Thanks.</p>
