iPhone 3.x and 4.x: shouldAutorotateToInterfaceOrientation is returning TRUE, but nothing happens

Question

shouldAutorotateToInterfaceOrientation is definitely being called... but when I rotate the iphone... or the simulator... nothing changes.

I thought all I had to do was this:

-(BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{
   NSLog(@"this is being called ok");
   return(YES);     // Or return(TRUE);
}

But I guess there is something else I need to set????

Answer 1

I think all the view controllers added to a tab bar controller must support an orientation in order for the tab bar controller to support it (by default, UIViewController only supports portrait orientation). Otherwise, the interface would get mangled if you rotated to landscape on a tab that supported it, then switched to a tab that did not.
