Google iPhone app status bar animation how did they do it?

I was playing with the Google App for iPhone and when i viewed a website the title of the page appeared over the classic status bar with a nice fade-in animation, after 4-5 seconds the title view disappeared with a nice fade-out animation.

How did they do that? did they hide the status bar with [[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES] and then added somehow the animation in the empty space? from my experience you can't fill that space without telling a viewController to "want fullscreen layout".

Another idea using "wants fullscreen layout" is to hide the status bar with [[UIApplication sharedApplication] setStatusBarHidden:YES animated:NO] and add an UIView as a subview to the controller's view and animate that(fade-in/fade-out at regular intervals).

Any pointers on how can i achieve this?

You have to hide the iPhone's status bar by calling

[UIApplication sharedApplication].statusBarHidden = YES;

and add your view there!
