Play video fullscreen in landscape mode, when my entire application is in lock in portrait mode

I want to play video in landscape mode in fullscreen. And my application is lock in portrait mode. How to implement this. Please help me. Thanks in advance

I've done this in on of my app. To do this you need to check that is your viewcontroller that where you want to play a video.

• The first thing you have to do is check Device Orientation to Portrait,Landscape left, Landscape right in your project target

• In your AppDelegate do the below code

  -(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
  
      UIStoryboard *mainStoryboard;
      if (IS_IPHONE) {
          mainStoryboard= [UIStoryboard storyboardWithName:@"Main" bundle: nil];
      }
      else{
         mainStoryboard= [UIStoryboard storyboardWithName:@"Main_iPad" bundle: nil];
      }
  
      ViewControllerThatPlaysVideo *currentViewController=    ViewControllerThatPlaysVideo*)[mainStoryboard     instantiateViewControllerWithIdentifier:@"postDetailView"];
      if(navigationController.visibleViewController isKindOfClass:    [ViewControllerThatPlaysVideo class]]){
         if([currentViewController playerState])
              return UIInterfaceOrientationMaskLandscape|UIInterfaceOrientationMaskPortrait;
         return UIInterfaceOrientationMaskPortrait;
      }
      return UIInterfaceOrientationMaskPortrait;
  }
