UITabBarController inside a UIViewController = viewDidAppear: not called

Question

I start off with a login screen. Then after the user logs in I load a Viewcontroller with UITabBArController in it. The problem is viewdidAppear: does not get called for any of the individual viewControllers in the tabBarController.

I have a feeling that this is not the best programming practise so does anyone have any ideas how to improve the structure of my code or how to fix my problem ?

Answer 1

I'd guess your trouble here comes from incorrect use of UIViewController and UITabBarController.

UITabBarController exists as a container for multiple view controllers. It probably should not, itself, be contained. It's designed to sit at the top of a view controller hierarchy. So step one is probably to re-arrange your application so that the UITabBarController is no longer under anything else and see if that straightens you out.

After that, slev's approach of presenting the login view sounds like the right one.

Answer 2

I had a problem because I was subclassing also UITabBarControler where I have overridden viewDidAppear without calling [super viewDidAppear:...]

After calling this, viewDidAppear was called also inside sub-view-controller.
