This is something that Apple could totally provide at a global level. Subclasses of the UIViewController can override the willRotateToInterfaceOrientation:duration: method to define how they want to handle rotation events. Apple could modify the UIViewController's default behavior to not send rotation messages if a global "don't rotate" setting is set to true.
