I override -orientationChanged in my main ViewController to push ModalViewController A when the device is in landscape mode. When placed back in portrait mode, ModalViewController A is dismissed. However, there are other cases (after button touches) where ModalViewControllers B, C, or D are shown. When those are showing, if the device is turned landscape and turned back, ModalViewController B C or D is dismissed, inappropriately.
I can verify that -orientationChanged on my main ViewController is being messaged even when a ModalViewController is shown. Is there a condition I can add to my -orientationChanged method to bypass that code when ModalViewController B C or D is being shown?
Thank you!

The view's window property is non-nil if a view is currently visible, so check the main view in the view controller: Invoking the view method causes the view to load (if it is not loaded) which is unnecessary and may be undesirable. It would be better to check first to see if it is already loaded.
modalTransitionStyle = UIModalTransitionStyleCoverVertical; [self presentViewController:modalViewController animated:YES completion:nil];
The UIViewController class defines the shared behavior that's common to all view controllers. You rarely create instances of the UIViewController class directly. Instead, you subclass UIViewController and add the methods and properties needed to manage the view controller's view hierarchy.
You can check if the modalViewController property in your main viewcontroller is one of your view controllers.
