Iphone: Is it possible to hide the TabBar?

Question

I have an application that uses a TabBarController to switch between modes. When in a certain mode, I'd like to hide the tab bar until the steps of that mode have been completed. Note that I'm not using a navigation controller so I can't use the setHidesBottomBarWhenPushed method on the navigation controller to hide the tab bar.

When I attempt to hide the tarbar using:

self.tabBarController.tabBar.hidden = YES

the tab bar goes away, but it leaves a 50 pixel blank area at the bottom of the screen where the tab bar used to be. I can't seem to figure out how to fill that area. Anything in the UI that is in that area is clipped and cannot be seen.

Any ideas if this is even possible? I'd really like to stay away from the navigation controller...

Thanks

Answer 1

Do you have the autoResizingMask set on the sub view?

view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

Something like that should do the trick and allow the view sitting atop the stack to re-size.

Answer 2

Why are you not using a navigation controller. It's a lot easier to hide the nav bar than the tab bar...

In summary, you can see an example of this behavior in this sample code:
