Question

我以全屏模式启动MPMoviePlayerController，然后使用默认按钮关闭它。它就像iOS4.3上的魅力一样，但在iOS5.0上留下了黑屏:(

我做错了吗？这是我的代码：

显示播放器：

- (void)showVideo {

MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:theURL];  

// Register to receive a notification when the movie has finished playing.  
[[NSNotificationCenter defaultCenter] addObserver:self  
                                         selector:@selector(moviePlayBackDidFinish:)  
                                             name:MPMoviePlayerPlaybackDidFinishNotification  
                                           object:moviePlayer];      



moviePlayer.controlStyle = MPMovieControlStyleFullscreen;
moviePlayer.scalingMode = MPMovieScalingModeAspectFit;
moviePlayer.shouldAutoplay = YES;  
moviePlayer.view.frame = [[UIScreen mainScreen] applicationFrame];
moviePlayer.view.transform = CGAffineTransformMakeRotation(1.57079633);    

[self.view addSubview:moviePlayer.view];  

[moviePlayer setFullscreen:YES animated:NO];  
}

关闭播放器：

- (void) moviePlayBackDidFinish : (NSNotification *) notification
{
MPMoviePlayerController *moviePlayer = [notification object];  
[[NSNotificationCenter defaultCenter] removeObserver:self  
                                                name:MPMoviePlayerPlaybackDidFinishNotification  
                                              object:moviePlayer];  

[moviePlayer.view removeFromSuperview];

[moviePlayer stop];
[moviePlayer release];  

//otherwise the status bar hides or changes color from time to time 
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:NO];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault];
}

我在更新到iOS5后一直在尝试解决同样的问题。

这是我到目前为止所提出的：

进入全屏模式后，这是MPMoviePlayerController中的一个错误。基本上你不能离开全屏模式。但这应该   如果我们只删除MPMoviePlayerController就可以解决。但没有运气   那里...

在使用视频播放器进入全屏后，主视图是否无法重新开始重绘？（暂停重绘视图   在de fullscreen下应该提高视频播放的性能。和   据我所知，情况确实如此。）

这是一个解决方案：（tkx去找我原来问题的大学）

不要进入全屏模式，只需将MPMoviePlayerController拉伸到父视图边界即可。这里的问题就是如果我们旋转我们的屏幕自动旋转那个全屏模式给出的是不会被使用。

//instead of going to fullscreen
//[moviePlayer setFullscreen:YES animated:YES];    
[moviePlayer.view setFrame:self.view.bounds];

//when the movie has finished playing release it

Answer 2

更改

player.controlStyle = MPMovieControlStyleFullscreen;

到

player.controlStyle = MPMovieControlStyleDefault;

并在MPMoviePlayer中执行了ExitFullscreen Notification

 [player setControlStyle:MPMovieControlStyleNone];

Answer 3

[moviePlayer stop];
[moviePlayer release];
[moviePlayer.view removeFromSuperview];

MPMoviePlayerController未在iOS5.0上关闭
