如何只旋轉subclassed mpmovieplayer控制器，並保持其他視圖固定到肖像

Question

我使用xcdYoutubeVideoViewController從MPMoviePlayerController的子類。我的申請是肖像。要啓動movieplayer，我這樣做：

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

其中，Vc是XCDYouTubeVideoPlayerViewController的實例。我怎樣才能允許旋轉只在這個視圖和按下完成按鈕在movieplayer把應用程序回到肖像？

Answer 1

您應該在每個視圖控制器中覆蓋：-(BOOL) shouldAutorotate。如果您希望該視圖控制器以其他方式旋轉NO，則返回YES。一定要檢查故事板設置中支持的方向。

更新：在你父控制器呈現玩家嘗試這個辦法：

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

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

如果應用程序根控制器導航控制器，子類UINavigationViewController和使用該類創建的應用程序根視圖控制器應用代理

@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]; 
}
