iPhone无法使用MPMoviePlayerViewController将电影旋转到横向模式

[update]

按照建议，我更改了所有父视图控制器以支持所有方向。我的app结构如下：AppDelegate> RootViewController> Videos> VideoDetails> MPMoviePlayerViewController。

As was recommended I changed all the parent view controllers to support all orientations. My app structure is as follows: AppDelegate > RootViewController > Videos > VideoDetails > MPMoviePlayerViewController.

如果我改变所有这些以支持所有方向，视频将以横向播放。但支持所有方向并不是我想要的，并导致其他问题。还有其他工作或我可以做的其他事情吗？

The video will play in landscape if I change all these to support all orientations. But supporting all orientations is not what I want and causes other issues. Is there any other work around or anything else I can do?

谢谢

我有一个基于肖像的iPhone应用程序，它使用MPMoviePlayerViewController的自定义子类显示视频。当用户按下播放时，我创建了这个类的实例并按模式呈现它如下：

I have an portrait based iPhone app that displays videos using a custom subclass of MPMoviePlayerViewController. When the user presses play I create an instance of this class and present it modally as follows:

- (IBAction) playPressed:(id)sender {

NSString *filepath = [[NSBundle mainBundle] pathForResource:self.currentVideoModel.videoFileName ofType:@"m4v"];
NSURL *fileURL = [NSURL fileURLWithPath:filepath];

// MovieViewController is just a simple subclass of MPMoviePlayerViewController
self.moviePlayerController = [[MovieViewController alloc] initWithContentURL:fileURL]; 

// full screen code.
[self.moviePlayerController.moviePlayer setScalingMode:MPMovieScalingModeFill];
[self.moviePlayerController.moviePlayer setFullscreen:TRUE];

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

[self presentMoviePlayerViewControllerAnimated:self.moviePlayerController];
}

问题是它在肖像方面表现不错，但当我将iPhone转为视频仍然以纵向而不是横向播放:(应用程序中的所有视图控制器仅支持纵向方向。

The problem is that it plays fine in portrait but when I turn the iPhone to landscape the video still plays in portrait and not landscape :( All the view controllers in the app only support portrait orientation.

我的MPMoviePlayerViewController子类仅覆盖以下方法以允许方向更改但没有影响：

My MPMoviePlayerViewController subclass only overrides the following method to allow for orientation changes but it has no affect:

- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
return (toInterfaceOrientation == UIInterfaceOrientationPortrait || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight || toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}

我甚至尝试以编程方式旋转视频，但绝对没有运气，它始终处于纵向模式。

I've even tried to programmatically rotate the video but with absolutely no luck, it always stays in portrait mode.

- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {

if (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight) {
    [self.view setTransform:CGAffineTransformMakeRotation(M_PI / 2)];
    return true;
}
else if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft) {
    [self.view setTransform:CGAffineTransformMakeRotation(M_PI * 2)];
    return true;
}
else if (toInterfaceOrientation == UIInterfaceOrientationPortrait) {
    [self.view setTransform:CGAffineTransformIdentity];
    return true;
}
else return false;

}
