Overlay a view over whole screen, when using UITabBarController?

Question

I want to overlay a HUD-style transparent graphic over the entire screen in a UITabBarController setup. The button to do this is in the first tab's screen (FirstViewController), and the overlay should also cover the tabs... is this possible?

Answer 1

You could attach your new view to your window directly.

[[[UIApplication sharedApplication] keyWindow] addSubview:myNewView];
