如何在ios7.mp4播放视频

Question

我无法播放视频，因为我有此通知错误：

    - (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

您需要找出出现播放错误的原因，以便您可以找出需要做什么才能解决问题。

查看这个密切相关问题的答案，您将看到以下代码片段：

    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，您可能会弄清楚您的应用程序到底出了什么问题。 祝你好运！
