Iphone MPMoviePlayerController不响应设置全屏=否

我正在使用MPMovieController作为基础创建一个自定义MovieController。我可以通过呼叫将视频切换到全屏

_[moviePlayer setFullscreen:YES animated:YES];_

调用相同的函数（[moviePlayer setFullscreen:否动画：是]；）将电影播放器恢复到原始状态（即当用户按下“完成”按钮时）不起作用

作为替代方案，我也试着-

a） 因此，收听MPMoviePlayerDidExitFullscreenNotification并调用movieplaybackdidfish:function

b） 使用以下命令从“完成”功能内部发布我的自定义通知：

NSDictionary *thisDictionary = [NSDictionary dictionaryWithObject:[NSNumber numberWithInt:MPMovieFinishReasonUserExited] forKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];  
[[NSNotificationCenter defaultCenter] postNotificationName:MPMoviePlayerDidExitFullscreenNotification object:moviePlayer userInfo:thisDictionary];

但在所有这些情况下，电影播放器视图不会恢复到其原始状态

请帮忙

谢谢

您必须注册事件通知。当你准备播放视频时，要这样做

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

  [[UIApplication sharedApplication] setStatusBarHidden:YES];
  [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification 
        object:nil];


[self dismissModalViewControllerAnimated:YES];

在你的电影回放中，像这样做

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

  [[UIApplication sharedApplication] setStatusBarHidden:YES];
  [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification 
        object:nil];


[self dismissModalViewControllerAnimated:YES];
