完成播放时iOS 6，Xcode 4.5视频无法退出 [英] iOS 6, Xcode 4.5 video not exiting when done playing

问题描述

我正在使用此代码在iOS 6上播放视频：

I am using this code to play a video on iOS 6:

-(void)GrommeVideo4
{
NSURL *url5 = [NSURL fileURLWithPath:[[NSBundle mainBundle]
                                      pathForResource:@"Flickers" ofType:@"mp4"]];
grommePlayer4 =  [[MPMoviePlayerController alloc]
                  initWithContentURL:url5];

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

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayerWillExitFullscreen:)
                                             name:MPMoviePlayerWillExitFullscreenNotification
                                           object:nil];

grommePlayer4.controlStyle = MPMovieControlStyleDefault;
grommePlayer4.shouldAutoplay = YES;
[self.view addSubview:grommePlayer4.view];
[grommePlayer4 setFullscreen:YES animated:YES];
}

-(void) moviePlayBackDidFinish:(NSNotification *)aNotification{
[grommePlayer4.view removeFromSuperview];
grommePlayer4 = nil;
}


- (void)moviePlayerWillExitFullscreen:(NSNotification*) aNotification {
[grommePlayer4 stop];
[grommePlayer4.view removeFromSuperview];
grommePlayer4 = nil;
}

我可以随时按完成退出视频，它工作正常，但当我观看视频到最后，它只显示一个黑屏。关于为什么会发生这种情况的任何想法？

And I can press "Done" to exit the video at any time, and it works fine, but when I watch the video through to the end, it just displays a black screen. Any ideas as to why this could occur?
