   I'm working an an iPad update and I'm using the UIAlertView to present some information. Following on the following notifications, I've got the Cocos2D elements and screens rotating correctly.

   [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:) name:@"UIDeviceOrientationDidChangeNotification" object:nil];

   - (void) orientationChanged:(NSNotification *)notification
   {
           UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];
   
           // Bail out if the orientation should be ignored
           if (orientation == UIDeviceOrientationUnknown||orientation == UIDeviceOrientationFaceDown||orientation == UIDeviceOrientationFaceUp) return;
   
           [[CCDirector sharedDirector] setDeviceOrientation:(ccDeviceOrientation)orientation];
   }

   I tried playing around with setting the alertview's transform property, with no real success since the application can launch in any orientation and rotate to any orientation. Has anyone had success with keeping an alert always in the correct rotation regardless of the device orientation?

   Thanks,
   Derek

   Anybody? Has someone not had to rotate an AlertView based on the device being in portrait or landscape view?

   In order to have alert views rotate properly, you need to have an active ViewController whose "shouldAutorotateToInterfaceOrientation" returns true. Same goes for store kit popups (which I suspect use AlertViews).

   viewController = [[MyViewController alloc] init];
   [window addSubview:viewController.view];

   It's important to add this view Controller's view to the window BEFORE attaching Cocos to the window. That way, it's hidden underneath Cocos and you don't see the stupid black triangle effect in the corners while the screen is rotating. But, the alerts will still all appear on top as expected.

   [[CCDirector sharedDirector] setDeviceOrientation:CCDeviceOrientationPortrait];
   
   dummyController = [[DummyController alloc] init];
   [window addSubview:dummyController.view];
   
   // create an openGL view inside a window
   [[CCDirector sharedDirector] attachInView:window];
   [window makeKeyAndVisible];

   DummyController subclasses UIViewController and has the shouldAutoroateToInterfaceOrientation method set to true. What am I missing? The keyboard and alert stay in their initial orientation while in the background cocos2d opengl view is rotating as expecting?

   On the surface, your code looks pretty much identical to mine. I assume you called beginGeneratingDeviceOrientationNotifications, because otherwise no orientation changes would work...? I can't really think of anything else. It works A-OK in my project, here's my init code:

   window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
   
   if(![CCDirector setDirectorType:CCDirectorTypeDisplayLink])
   	[CCDirector setDirectorType:CCDirectorTypeDefault];
   
   [[CCDirector sharedDirector] setPixelFormat:kPixelFormatRGB565];
   [CCTexture2D setDefaultAlphaPixelFormat:kTexture2DPixelFormat_RGBA8888];
   [[CCDirector sharedDirector] setAnimationInterval:1.0f/60];
   
   [Utils checkForiPad];
   
   if([Utils isiPad])
   	{
   	viewController = [[MyViewController alloc] init];
   	[window addSubview:viewController.view];
   	[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
   	}
   
   [window setUserInteractionEnabled:true];
   [window setMultipleTouchEnabled:true];
   [[CCDirector sharedDirector] attachInWindow:window];
   [window makeKeyAndVisible];
   
   // Other init code
   
   [[CCDirector sharedDirector] runWithScene:[MenuLayer scene]];

   (Mine is a universal app and I only want to generate orientation changes if its the iPad version)
