iphone - 没有互联网连接时 dismissModalViewController 不工作 MPMoviePlayerViewController

Question

我有一个使用 presentModalViewController:animated: 调用的 MPMoviePlayerViewController。当出现错误(无互联网连接)时，我想将其关闭。但是，dismissModalViewController 在这种情况下似乎不起作用。

- (void)movieFinishedCallback:(NSNotification*)aNotification
{      
     NSLog(@"MOVIE FINISH CALL");

    // Obtain the reason why the movie playback finished
    NSNumber *finishReason = [[aNotification userInfo] objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];    
    // Dismiss the view controller ONLY when the reason is not "playback ended"

    if ([finishReason intValue] != MPMovieFinishReasonPlaybackEnded)
    {     

        NSlog(@"Check go here");
        MPMoviePlayerController *moviePlayer = [aNotification object];     
        [[NSNotificationCenter defaultCenter] removeObserver:self
                                                        name:MPMoviePlayerPlaybackDidFinishNotification
                                                      object:moviePlayer];        
        [self dismissModalViewControllerAnimated:YES];
    }
    else{
        [self dismissModalViewControllerAnimated:YES];        
    }
}



- (void)playPodcastRadio:(NSString *) urlRadio
{
     // Initialize the movie player view controller with a video URL string

    MPMoviePlayerViewController* mediaPlayer = [[MPMoviePlayerViewController alloc]initWithContentURL:[NSURL URLWithString:urlRadio]];
    mediaPlayer.moviePlayer.movieSourceType = MPMovieSourceTypeUnknown; 

    [[NSNotificationCenter defaultCenter] removeObserver:mediaPlayer name:MPMoviePlayerPlaybackDidFinishNotification object:mediaPlayer.moviePlayer];

    // Register this class as an observer instead    
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(movieFinishedCallback:) name:MPMoviePlayerPlaybackDidFinishNotification  object:mediaPlayer.moviePlayer];

    mediaPlayer.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
    // Present the movie player view controller    
    [self presentModalViewController:mediaPlayer animated:YES];

    [mediaPlayer.moviePlayer prepareToPlay];
    [mediaPlayer.moviePlayer play];
}

通知处理程序被调用并到达Check go here 日志。但它不会关闭 modalViewController。谁能帮帮我？

谢谢

它发生在 iOS 4.3 和 iOs 5 上

“要关闭模态呈现的电影播放器​​ View Controller ，请调用 dismissMoviePlayerViewControllerAnimated 方法。”
