I have noticed behavior where if a parent controller (like UINavigationController or UITabBarController) never get's viewWill/DidAppear called on it, it won't call it on the child controllers either. So make sure that in the code where you create the parent controller, you call viewWillAppear, show it, then call viewDidAppear. Then it should make those calls on it's child controllers as is appropriate.

Double check the parent controller is having those methods called, and call them yourself if they are not.
