iphone - 当项目设置允许所有旋转时，在特定 View Controller 中禁用旋转

Question

问题是 asked earlier .我遇到了同样的问题，电影播放器​​没有旋转，因为项目属性不允许旋转。这个问题只在 iPhone 上的 iOS7 中遇到过，所以我正在尝试另一种解决方法，我在项目属性中启用所有方向，但问题是，每当我通过这样的函数禁用其他 View Controller 中的旋转时

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
     return FALSE;
}

// Tell the system what we support
-(NSUInteger)supportedInterfaceOrientations
 {
return UIInterfaceOrientationPortrait;
}

- (BOOL) shouldAutorotate {
return NO;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return UIInterfaceOrientationPortrait;

}

View Controller 仍在旋转，我想这是因为它在项目属性中允许。

所以问题是..

How can i disable Rotation in a specific Media Player View Controller when Project settings allows all rotation?

OR

How can i Override rotation in a specific Media Player view controller over project properties (Disabling rotation) which doesn't work in iOS7

Answer 1

您可以在 AppDelegate 类中实现以下方法，它对我有用:

 - (NSUInteger) application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {

    if ([[window.rootViewController presentedViewController] isKindOfClass:[MPMoviePlayerViewController class]])
    {
        return UIInterfaceOrientationMaskAllButUpsideDown;
    }
    else
    {
        return UIInterfaceOrientationMaskPortrait;
    }
}
