Huh I found maybe a specific solution so I replace the if (leaderboardController! = nil){...} by the code below.
You have to subclass both of your view controllers, the parent view controller and the modal view controller it presents (somebody correct me if i'm wrong, but child controllers only handle rotation if their parent also handles them) and override the method called.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
