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)

Inspired by rdelmar's answer to another question, I recommend putting your UITabBarController in Container View other ViewController. Then add your hud onto ViewController view.
