ios – 如何拦截AVPlayerViewController中的完成按钮？

我创建一个AVPlayerViewController&在自定义UIViewController的viewDidAppear方法中附加的AVPlayer,但是当我按完成按钮时,我的自定义视图控制器将自动关闭.

我想拦截这个动作,以便我自己解开Segue,但我不知道该怎么做？我找到了MPMoviePlayerViewController但不是AVPlayerViewController ..

我找到的代码MPMoviePlayerViewController在下面..

- (void)playVideo:(Nsstring*)aVideoUrl
{
    // Initialize the movie player view controller with a video URL string
    MPMoviePlayerViewController *playerVC = [[[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:aVideoUrl]] autorelease];

// Remove the movie player view controller from the "playback did finish" notification observers
[[NSNotificationCenter defaultCenter] removeObserver:playerVC
                                                name:MPMoviePlayerPlaybackDidFinishNotification
                                              object:playerVC.moviePlayer];

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

// Set the modal transition style of your choice
playerVC.modalTransitionStyle = UIModalTransitionStyleCrossdissolve;

// Present the movie player view controller
[self presentModalViewController:playerVC animated:YES];

// Start playback
[playerVC.moviePlayer preparetoPlay];
[playerVC.moviePlayer play];
}

- (void)movieFinishedCallback:(NSNotification*)aNotification
{
// 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)
{
    MPMoviePlayerController *moviePlayer = [aNotification object];

    // Remove this class from the observers
    [[NSNotificationCenter defaultCenter] removeObserver:self
                                                    name:MPMoviePlayerPlaybackDidFinishNotification
                                                  object:moviePlayer];

    // dismiss the view controller
    [self dismissModalViewControllerAnimated:YES];
}

我问苹果这个问题,他们回答如下：

感谢您联系Apple开发人员技术支持(DTS).我们的工程师已经审查了您的请求,并得出结论,鉴于目前的运输系统配置,没有任何支持的方式来实现所需的功能.

- (void) viewWilldisappear:(BOOL)animated {
    [[NSNotificationCenter defaultCenter] postNotificationName:kPlayerViewdismissednotification object:nil];
    [super viewWilldisappear:animated];
}
