How Did the Digg App Master search button

[RyzOn]

I' am really impressed by the way the digg app has included a smooth pop over animation when clicking the search button at the top of the navigation bar.

I've reviewed numerous tutorials, but i have found nothing that outlines this exact example.

Does anyone know how i can implement the same type of search functionality into an app? I would appreciate any help you can provide.

I'm not familiar with exactly what it does, but from their screen shots, I don't see any reason to assume they are doing anything special.
