iPhone 在视频播放后强制方向

Question

我遇到了一个困扰我的问题，应该很容易解决。这是我的代码:

-(IBAction)playMovie:(id)sender{

    NSString *filepath   =   [[NSBundle mainBundle] pathForResource:@"myMovie" ofType:@"MOV"];  
    NSURL    *fileURL    =   [NSURL fileURLWithPath:filepath];  
    moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];  

    [[NSNotificationCenter defaultCenter] addObserver:self  
                                             selector:@selector(moviePlaybackComplete:)  
                                                 name:MPMoviePlayerPlaybackDidFinishNotification  
                                               object:moviePlayerController];  

    [self.view addSubview:moviePlayerController.view];  
    //[moviePlayerController setOrientation:UIInterfaceOrientationLandscapeLeft];
    moviePlayerController.fullscreen = YES;  
    moviePlayerController.scalingMode = MPMovieScalingModeFill;    

    [moviePlayerController play]; 

}

- (void)moviePlaybackComplete:(NSNotification *)notification  
{  

    [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait];

    moviePlayerController = [notification object];  
    [[NSNotificationCenter defaultCenter] removeObserver:self  
                                                    name:MPMoviePlayerPlaybackDidFinishNotification  
                                                  object:moviePlayerController];  

    [moviePlayerController.view removeFromSuperview];  
    [moviePlayerController release];  
}  

方向:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
    if(UIInterfaceOrientationIsPortrait(toInterfaceOrientation)) {
        return(YES);
    }

    if(UIInterfaceOrientationIsLandscape(toInterfaceOrientation)) {
        return([moviePlayerController isFullscreen]);
    }




    return(NO);

}

一开始这会按预期工作。方向最初强制为纵向，然后播放电影，横向允许电影旋转并以横向方式观看。然后单击完成后，电影结束，界面将保持横向。我需要将其强制返回纵向模式...我见过类似的解决方案

[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationPortrait];

现在似乎从 ios 4.0 开始已弃用

理想情况下，一旦电影完成方法触发，它应该自动旋转到纵向!

有什么解决办法吗？

试试这个:

[[NSNotificationCenter defaultCenter] addObserver:self  
                                         selector:@selector(moviePlaybackComplete:)  
                                         name:MPMoviePlayerWillExitFullscreenNotification  
                                         object:moviePlayerController];
