MPMoviePlayer-Notification 未被调用

Question

您好，

我想使用 MPMoviePlayerViewController 播放电影并收听 MPMoviePlayerPlaybackDidFinishNotification，但它没有被调用。对此有什么想法吗？ 获得任何提示都会有帮助..谢谢你 这是我的代码：

NSString *url   =   [[NSBundle mainBundle] pathForResource:[sender contentName] ofType:@"m4v"];
    MPMoviePlayerViewController* moviePlayerController = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL fileURLWithPath:url] ];

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackComplete:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayerController];

    moviePlayerController.moviePlayer.controlStyle = MPMovieControlStyleFullscreen;
    [self presentMoviePlayerViewControllerAnimated:moviePlayerController];
    [moviePlayerController.moviePlayer play]; 
}


- (void) moviePlayBackComplete:(NSNotification*) notification {
    NSLog(@"moviePlayBackComplete complete");

    MPMoviePlayerController* moviePlayerController = [notification object];
    [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayerController];  

    [self dismissMoviePlayerViewControllerAnimated];
    [moviePlayerController release];
}

您正在尝试从 MPMovePlayerViewController 获取通知，但我很确定只有 MPMoviePlayerController 提供这些通知。尝试更改您的通知设置

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackComplete:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayerController.moviePlayer];
