如何仅旋转子类化的mpmovieplayer控制器并使其他视图固定为人像 [英] How to rotate only the subclassed mpmovieplayer controller and keeping other views fixed to portrait

问题描述

我正在使用xcdYoutubeVideoViewController，它是MPMoviePlayerController的子类.我的申请是纵向的.要启动电影播放器​​，我正在这样做:

I am using xcdYoutubeVideoViewController which is subclassed from MPMoviePlayerController. My application is in portrait. To launch the movieplayer, I am doing this:

UINavigationController *navBarController = (UINavigationController*)[[[UIApplication sharedApplication] keyWindow] rootViewController] ;
[navBarController presentMoviePlayerViewControllerAnimated:vc];

其中vc是XCDYouTubeVideoPlayerViewController的实例.如何仅在此视图中允许旋转，并在Movieplayer中按完成"按钮将应用程序恢复为纵向?

where vc is instance of XCDYouTubeVideoPlayerViewController. How can I allow rotation only in this view and on pressing done button in movieplayer bring the application back to portrait?

推荐答案

您应该在每个视图控制器中覆盖:-(BOOL) shouldAutorotate.如果您希望该视图控制器旋转NO，则返回YES.请确保在情节提要设置中检查支持的方向.

You should override: -(BOOL) shouldAutorotate in each view controller. Return YES if you want that view controller to rotate NO otherwise. Be sure to check the supported orientation on your storyboard setting.

更新:在显示播放器的父控制器中，尝试以下操作:

Update: In your parent controller that presents the player try this:

- (BOOL)shouldAutorotate
{
     // 1. check if the parent presentedViewController is the nav containing the player

     // 2. if yes, return YES, NO otherwise
}

如果应用程序根控制器是导航控制器，请子类UINavigationViewController并使用该类在App Delegate中创建应用程序根视图控制器

If the app root controller is a Navigation Controller, subclass UINavigationViewController and use that class in creating the app root view controller in App Delegate

@implementation ANavigationViewControllerSubClass


- (BOOL)shouldAutorotate
{
    return [self.topViewController shouldAutorotate];
}

- (NSUInteger)supportedInterfaceOrientations
{
    return [self.topViewController supportedInterfaceOrientations];
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{ 
    return [self.topViewController preferredInterfaceOrientationForPresentation];
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return [self.topViewController   shouldAutorotateToInterfaceOrientation:interfaceOrientation];
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return [self.topViewController preferredInterfaceOrientationForPresentation]; 
}
