In an iPad app, I have five regular view controllers (not navigation controllers or anything like that) inside a tab bar controller. The tab bar controller is just a plain UITabBarController declared in the app delegate.

All the view controllers return YES in the shouldAutorotateToInterfaceOrientation method.

On both the simulator and device, on rotation, the tab bar rotates properly but the currently selected view controller (call it A) does not.

If I switch to another view controller B and then back to A (without rotating the device again), A appears correctly rotated.

This happens with any of the five view controllers

Why doesn't the currently selected view controller rotate and how do I fix it?

Thanks.
