iPhone + UINavigationBar

I have UINavigationController in my application, at some point I hide NavigationBar u开发者_如何学JAVAsing following code:

self.navigationController.navigationBarHidden = YES;

Because of this my View is disturbed and there is a gap displayed at the bottom.

I ended up adding 20px to the view's frame height. You could try using autoresizessubviews & autoresizingmask
