xcode - iOS 6、Xcode4.5ビデオの再生が終了しても終了しない

Question

私はこのコードを使用してiOS6でビデオを再生しています：

-(void)GrommeVideo4
{
NSURL *url5 = [NSURL fileURLWithPath:[[NSBundle mainBundle]
                                      pathForResource:@"Flickers" ofType:@"mp4"]];
grommePlayer4 =  [[MPMoviePlayerController alloc]
                  initWithContentURL:url5];

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

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayerWillExitFullscreen:)
                                             name:MPMoviePlayerWillExitFullscreenNotification
                                           object:nil];

grommePlayer4.controlStyle = MPMovieControlStyleDefault;
grommePlayer4.shouldAutoplay = YES;
[self.view addSubview:grommePlayer4.view];
[grommePlayer4 setFullscreen:YES animated:YES];
}

-(void) moviePlayBackDidFinish:(NSNotification *)aNotification{
[grommePlayer4.view removeFromSuperview];
grommePlayer4 = nil;
}


- (void)moviePlayerWillExitFullscreen:(NSNotification*) aNotification {
[grommePlayer4 stop];
[grommePlayer4.view removeFromSuperview];
grommePlayer4 = nil;
}

また、[完了]を押すといつでもビデオを終了でき、正常に機能しますが、ビデオを最後まで見ると、黒い画面が表示されます。なぜこれが発生する可能性があるのか​​についてのアイデアはありますか？

Answer 1

これを試してみてください、それが役立つことを願っています

-(void)GrommeVideo4
{
    NSURL *url5 = [NSURL fileURLWithPath:[[NSBundle mainBundle]
                                      pathForResource:@"Flickers" ofType:@"mp4"]];
    grommePlayer4 =  [[MPMoviePlayerController alloc]
                  initWithContentURL:url5];

    grommePlayer4.controlStyle = MPMovieControlStyleDefault;
    grommePlayer4.shouldAutoplay = YES;
    [self.view addSubview:grommePlayer4.view];
    [grommePlayer4 setFullscreen:YES animated:YES];
}

-(void) moviePlayBackDidFinish:(NSNotification *)aNotification{
    [grommePlayer4.view removeFromSuperview];
    grommePlayer4 = nil;
}


- (void)moviePlayerWillExitFullscreen:(NSNotification*) aNotification {
    [grommePlayer4 stop];
    [grommePlayer4.view removeFromSuperview];
    grommePlayer4 = nil;
}

moviePlayBackDidFinishでプレーヤーも停止しようとしましたか？
