次のコードを実行しています。ビデオは正常に再生されますが、終了後は黒い画面になり、元のビューに戻ることはありません。黒い画面をタップすると、「読み込んでいます.....」というメッセージが表示されます。何が間違っているのか誰か説明してください。ありがとう

- (IBAction)video:(UIBarButtonItem *)sender
{
    {
        NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
                                             pathForResource:@"IMG_0973" ofType:@"MOV"]];
        moviePlayer=[[MPMoviePlayerController alloc] initWithContentURL:url];


        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayer];
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDonePressed:) name:MPMoviePlayerDidExitFullscreenNotification object:moviePlayer];



        moviePlayer.controlStyle=MPMovieControlStyleDefault;
        //moviePlayer.shouldAutoplay=NO;
        [moviePlayer play];

この通知メソッドを追加

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePreloadDidFinish:) name:MPMoviePlayerLoadStateDidChangeNotification
                                               object:player];

このメソッドは、ムービーがロードされた後に呼び出され、このメソッドで moviePlayer ビューを追加します。

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

   moviePlayer.controlStyle=MPMovieControlStyleDefault;
   [self.view addSubview:moviePlayer.view];
   [moviePlayer play];
   [moviePlayer setFullscreen:YES animated:YES];

    if (moviePlayerViewController)
    {
        [moviePlayerViewController.moviePlayer setMovieSourceType:MPMovieSourceTypeFile];

        [moviePlayerViewController.moviePlayer setFullscreen:YES];

        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(MovieFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayerViewController.moviePlayer];

        [moviePlayerViewController.moviePlayer play];

        [navi presentModalViewController:moviePlayerViewController animated:NO];

        [moviePlayerViewController release];

        moviePlayerViewController  = nil;
    }

}
-(void)MovieFinished:(NSNotification *)notification
