Answer 1

Change to:

[[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(onStop:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:movieController];

and

-(void)onStop:(NSNotification*)notification
{


}

It works for me.

Answer 2

This is from the documentation for MPMoviePlayerController

This notification is not sent when a movie is displaying in fullscreen mode and the user taps Done. The Done button pauses playback and causes the movie player to exit fullscreen mode. To detect this scenario, register for other notifications such as MPMoviePlayerDidExitFullscreenNotification.

Perhaps that might help you
