Xcode 4.5 iOS 6.0 simulator orientation not working

Question

I have updated my Xcode to 4.5 , I have implemented the orientation methods as below

  -(BOOL)shouldAutorotate{

    return YES;

  }

-(NSUInteger)supportedInterfaceOrientations{

    return UIInterfaceOrientationMaskAll;
}

I am setting the frame sizes of buttons ,labels,images in willRotateToInterfaceOrientation method

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration{


  if ([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortrait )||
        ([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortraitUpsideDown ))
  {

    // set frame sizes for portait

   }

  else if(( [[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeLeft )||
            ([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeRight ))

  {

    // set frame sizes for landscape

   }

}

but sometimes this method is not getting called when rotating the simulator and sometimes the simulator is not detecting orientation when navigating from another viewController . I have checked info.plist file - it is fine.

Apple does not call the shouldAutorotatetoInterfaceOrientation call in IOS 6.0 unless you tell the main window which view controller to send it to.

I got rotation to work in my app by setting the window.rootViewController to the top level view controller of my app in

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
   ...
   window.rootViewController = topLevelViewController;
   ...
}

The iPhone version of my app only supports the two portrait orientations, so my top iPhone view controller required a new method:

- (NSUInteger)supportedInterfaceOrientations 
{
  return  UIInterfaceOrientationMaskPortrait |  
          UIInterfaceOrientationMaskPortraitUpsideDown;
}

here is a discussion on Buzz Touch.

Apple has deprecated shouldautorate method from ios6 use these methods instead

- (BOOL)shouldAutorotate NS_AVAILABLE_IOS(6_0);
- (NSUInteger)supportedInterfaceOrientations NS_AVAILABLE_IOS(6_0);
// Returns interface orientation masks.
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation NS_AVAILABLE_IOS(6_0);
