退出 MPMediaPlayerController 视图

Question

我正在编写一个简单的方法来全屏启动流媒体视频并让用户停止按“完成”按钮。问题是，我无法删除 MPMediaPlayerController 视图，或者可能我的操作方式错误。

- (IBAction)playVideoButtonPressed:(id)sender {
    NSURL *url = [NSURL URLWithString:@"http://mysite.com/video.mov"];
    mp = [[MPMoviePlayerController alloc] initWithContentURL: url];
    [[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayerPlaybackDidFinish:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:nil];

    if ([mp respondsToSelector:@selector(setFullscreen:animated:)]) {  
        mp.controlStyle = MPMovieControlStyleFullscreen;  
        mp.shouldAutoplay = YES;
        [self.view addSubview:mp.view];  
        [mp.view setTag:3];
        [mp setFullscreen:YES animated:YES];  
    }
    [[NSNotificationCenter defaultCenter] addObserver:self            
        selector:@selector(moviePlayBackDidFinish:) 
        name:MPMoviePlayerPlaybackDidFinishNotification
        object:mp];

    [mp play];
}

- (void)moviePlayBackDidFinish:(id)sender {
      NSLog(@"Quitting MoviePlayer");
      [mp.view removeFromSuperview];    
}

这个想法是，通过单击应用程序中的按钮来调用 MPMediaPlayerController 视图，并通过单击“完成”视频或视频结束时将其关闭。

我应该使用 MPMoviePlayerViewController。
