视频问题removeFromSuperview

Question

    NSString *urlStr = [[NSBundle mainBundle] pathForResource:@"clip" ofType:@"m4v"];
    NSURL *url = [NSURL fileURLWithPath:urlStr];
    moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
    moviePlayer.view.frame = CGRectMake(0, 0,320, 460);
    [viewController.view addSubview:moviePlayer.view];
    [moviePlayer setFullscreen:YES animated:YES];
    [moviePlayer setShouldAutoplay:YES]; 
    moviePlayer.scalingMode = MPMovieScalingModeAspectFit;
    [moviePlayer setMovieControlMode:MPMovieControlModeHidden];

我正在播放mp4文件我需要在电影结束时删除.FromSuperview ....在通知中。可能吗。

是的，这是可能的。您需要将Observers添加到MPMoviePlayer发送的通知中（可能在您的viewDidLoad中）：

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(exitedFullscreen)
                                             name:MPMoviePlayerDidExitFullscreenNotification
                                           object:nil];

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(finishedPlayback:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:nil];

然后在通知触发时调用的方法中：

- (void)finishedPlayback:(NSNotification *)notification
{
    [self.moviePlayer setFullscreen:NO animated:YES];
}

-(void)exitedFullscreen 
{
    [self.moviePlayer.view removeFromSuperView];
}
