Answer 1

I had the same issue as you and I fixed it with a kinda, ugly work around, basically I have a global variable in my app that I use to choose what the valid interface orientations are. In the

    - (NSInteger)application : (UIApplication *)supportedInterfaceOrientationsForWindow:(UIWindow *)window{
          if(orientationIndicator == 1){
               return UIInterfaceOrientationMaskAllButUpsideDown;
          }
          else if(orientationIndicator == 2){
               return UIInterfaceOrientationMaskLandscape;
          }
     }

To declare the global variable put this in your appDelegate.m file :

          int orientationIndicator = 1;

To import the global variable use :

          extern int orientationIndicator;

Then you can change the value of orientation indicator and it will allow you to run in different interface types. So what I did was I start by making the orientationIndicator = 1. When you authenticate a player and initiate the login view controller set the orientation indicator to 2. When you dismiss the view (authenticate the player) then you can change it back to 1.

This is a slimy work around but it has worked for me.

Hope this helps!
