Question

我无法播放视频，因为我收到此通知错误：

    - (void)playbackFinished:(NSNotification*)notification {
        NSNumber* reason = [[notification userInfo] objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];
        switch ([reason intValue]) {

            case MPMovieFinishReasonPlaybackError:{
                **NSLog(@"playbackFinished. Reason: Playback Error");**
                [UIView animateWithDuration:1.0f
                                      delay:0
                                    options:UIViewAnimationOptionCurveEaseIn
                                 animations:^{

                                     [m_player.view setAlpha:0];

                                 }
                                 completion:^(BOOL finished){

                                     [m_player.view removeFromSuperview];
                                     m_player = nil;
                                 }];
            }
                break;

            default:
                break;
        }


 }

感谢任何帮助！

你需要找出为什么你会收到播放错误，这样你就可以弄清楚需要做些什么才能解决问题。

查看this closely related question的答案，您会看到以下代码段：

    NSError *mediaPlayerError = [[notification userInfo] objectForKey:@"error"];
    if (mediaPlayerError) 
    {
        NSLog(@"playback failed with error description: %@", [mediaPlayerError localizedDescription]);
    }
    else
    {
        NSLog(@"playback failed without any given reason");
    }

将这些行添加到您的MPMovieFinishReasonPlaybackError案例中，您可能会发现应用程序的真正含义。祝你好运！
