推荐答案

嗯，有时候回答你自己的问题很傻，但它有助于帮助其他人面对同样的问题问题。

Well its sometimes silly to answer your own question but its good to help others who are facing the same problem.

在iOS 8中，而不是检查MPInlineVideoFullscreenViewController我们需要检查AVFullScreenViewController。以下是所有iOS版本的完整方法，即iOS 8及更低版本。

in iOS 8 instead of checking for MPInlineVideoFullscreenViewController we need to check for AVFullScreenViewController. So below is the complete method for all iOS versions i.e iOS 8 and less.

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

  if ([[window.rootViewController presentedViewController]
     isKindOfClass:[MPMoviePlayerViewController class]] || [[window.rootViewController presentedViewController] isKindOfClass:NSClassFromString(@"MPInlineVideoFullscreenViewController")] || [[window.rootViewController presentedViewController] isKindOfClass:NSClassFromString(@"AVFullScreenViewController")]) {

      return UIInterfaceOrientationMaskAllButUpsideDown;
  }else {

      if ([[window.rootViewController presentedViewController]
         isKindOfClass:[UINavigationController class]]) {

          // look for it inside UINavigationController
          UINavigationController *nc = (UINavigationController *)[window.rootViewController presentedViewController];

          // is at the top?
          if ([nc.topViewController isKindOfClass:[MPMoviePlayerViewController class]]) {
              return UIInterfaceOrientationMaskAllButUpsideDown;

              // or it's presented from the top?
          } else if ([[nc.topViewController presentedViewController]
                    isKindOfClass:[MPMoviePlayerViewController class]]) {
              return UIInterfaceOrientationMaskAllButUpsideDown;
          }
      }
  }

  return UIInterfaceOrientationMaskPortrait;
}
