title: iOS 8 MPMoviePlayerPlaybackDidFinishNotification not working
body: <p>I used Xcode 6 with iOS 8 SDK.</p>
  
  <p>If the video can't played, when starting MPMoviePlayer. MPMoviePlayerPlaybackDidFinishNotification not working.</p>
  
  <p>I reference this article：
  [<a href="https://stackoverflow.com/questions/5352870/how-to-get-an-error-description-when-playback-fails-on-mpmovieplayercontroller][1]">How to get an error description when playback fails on MPMoviePlayerController</a>
  but iOS8 doesn't work.</p>
  
  <pre><code>[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(MPFinished: ) name:MPMoviePlayerPlaybackDidFinishNotification object:self.MoviePlayer];
  </code></pre>
  
  <p>How to do that can solve this problem? Thanks.</p>
