我正在使用通知中心接收 MPMoviePlayerPlaybackDidFinishNotification，它按预期工作。

   NSURL * url = [[NSURL alloc] initWithString:@"http://INFINITECREATIVEUNIVERSE.COM/Media/module_1_Dec/c_January27AffactPerfect.mov"];

    moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];

    [moviePlayer.view setFrame:CGRectMake(0, 0, 500, 260)];

    [self.view addSubview:moviePlayer.view];

    //Some addiontal customization
    moviePlayer.fullscreen = YES;
    moviePlayer.allowsAirPlay = YES;
    moviePlayer.shouldAutoplay = YES;
    moviePlayer.controlStyle = MPMovieControlStyleEmbedded;
    //moviePlayer.endPlaybackTime = NO;
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(playMovieFinished:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:moviePlayer];

选择器做我想做的事。

-(void)playMovieFinished:(NSNotification*)theNotification
{
    [[NSNotificationCenter defaultCenter]
     removeObserver:self
     name:MPMoviePlayerPlaybackDidFinishNotification
     object:moviePlayer];
    //                     Change Segue ID Here    

    [self  performSegueWithIdentifier:@"VC_5" sender:self];
}

当我在视频仍在播放时单击下一步按钮时会出现我的问题。当我的下一个 ViewController 出现时，没有视频，我仍然可以听到来自前一个 ViewController 的音频。

我的问题是：如何正确关闭视图控制器和 MPMoviePlayer。我搞不清楚了。我从 Apple 下载了示例 MoviePlayer 项目，但现在已弃用，并且无法正常工作。我不知道如何使这项工作。我交叉手指，我已经正确地提出了这个问题。请怜悯我的新手问题。谢谢罗伯特

使用此代码

-(void)playMovieFinished:(NSNotification*)theNotification
{
    [[NSNotificationCenter defaultCenter]
     removeObserver:self
     name:MPMoviePlayerPlaybackDidFinishNotification
     object:moviePlayer];
    [moviePlayer stop];
    // Change Segue ID Here    

    [self  performSegueWithIdentifier:@"VC_5" sender:self];
}
