   So there have been lots of problems regarding orientations and iOS 6. I thought I had overcome them all, but alas have fallen at the last hurdle. My game is landscape only and rotates and works fine with Game Center.

   The only issue is that if you open Game Center achievements on iOS 6, rotate the device to portrait, and then close Game Center, it leaves the game in portrait. If you then rotate it fixes itself, but this is still a major problem.

   So far I have added Portrait in my Info.plist, added for iOS 6 the method

   - (NSUInteger) supportedInterfaceOrientations {
       return UIInterfaceOrientationMaskLandscape;
   }

   and changed the App Delegate:

   //[window addSubview: viewController.view]; <--- removed
   window.rootViewController = viewController; // replacement line

   To present the achievements I have in my menu scene:

   presentingViewController = [[UIViewController alloc] init];
   [[[[CCDirector sharedDirector] openGLView] window] addSubview:presentingViewController.view];
   [presentingViewController presentModalViewController: achievements animated: YES];

   And then have:

   -(void) achievementViewControllerDidFinish:(GKAchievementViewController *)viewController {
       [presentingViewController dismissModalViewControllerAnimated:YES];
       [presentingViewController.view.superview removeFromSuperview];
   }

   I tried using setDeviceOrientation in the above method, which worked, but then the orientations rotated by 90 degrees (so rotating to landscape put it in portrait)... Any help would be appreciated!

   yeah this was an annoying problem I managed to resolve. In supported orientations you leave portrait selected (so game centre works)
   The you need to subclass UINavigationController (i called it jimnav)

   nothing changed in the .h
   here is my .m
   

   #import "jimnav.h"
   
   @interface jimnav ()
   
   @end
   
   @implementation jimnav
   
   - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
   {
       self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
       if (self) {
           // Custom initialization
       }
       return self;
   }
   
   - (void)viewDidLoad
   {
       [super viewDidLoad];
   	// Do any additional setup after loading the view.
   }
   
   - (void)didReceiveMemoryWarning
   {
       [super didReceiveMemoryWarning];
       // Dispose of any resources that can be recreated.
   }
   
   - (BOOL)shouldAutorotate
   {
       return YES;
   }
   
   - (NSUInteger)supportedInterfaceOrientations
   {
       return UIInterfaceOrientationMaskLandscapeRight|UIInterfaceOrientationMaskLandscapeLeft;
   }
   
   - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
   {
       return UIInterfaceOrientationLandscapeLeft;
   }
   
   @end

   then in your app delegate
   navController_ = [[jimnav alloc] initWithRootViewController:director_];

   This allows gamecentre to be portrait, but prevents portrait when rotating the phone.

   Hope this helps

   Thanks for helping out, but where in the app delegate did you put the line below?

   navController_ = [[jimnav alloc] initWithRootViewController:director_];

   I don't actually have any UINavigationControllers in my app delegate. I'm using v1.1 (should have mentioned that earlier).
