代码示例

@property (nonatomic, strong) MPMoviePlayerController *moviePlayerController;

// 定义成局问变量时，黑屏无法播放，需要定义成全局变量，或属性
        self.moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:videoUrl];
        self.moviePlayerController.view.frame = self.view.bounds;
        [self.view addSubview:self.moviePlayerController.view];
        [self.moviePlayerController play];

// 通知
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(mediaPlayerPlaybackStateChange:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:self.moviePlayerController];
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(mediaPlayerPlaybackFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:self.moviePlayerController];
    
    // 播放状态改变，注意播放完成时的状态是暂停
    - (void)mediaPlayerPlaybackStateChange:(NSNotification *)notification
    {
        switch (self.moviePlayerController.playbackState) {
            case MPMoviePlaybackStatePlaying:
                NSLog(@"正在播放...");
                break;
            case MPMoviePlaybackStatePaused:
                NSLog(@"暂停播放.");
                break;
            case MPMoviePlaybackStateStopped:
                NSLog(@"停止播放.");
                break;
            default:
                NSLog(@"播放状态:%li", self.moviePlayerController.playbackState);
                break;
        }
    }
    
    // 播放完成
    - (void)mediaPlayerPlaybackFinished:(NSNotification *)notification
    {
        NSLog(@"播放完成.%li", self.moviePlayerController.playbackState);
        [self.moviePlayerController.view removeFromSuperview];
    }

注意：必须定义成全局变量，或属性；若定义成局部变量则黑屏不会显示。
