Focus and zoom in on a UITextField when touched?

Question

Hello -

How in the world does one get the iPhone view to zoom in on a focused UITextField? I need to tap on a text field that I want to edit, and my view should zoom in to the tapped text field and pull up the keyboard (which it already does), similar to how many Internet text fields gain focus on the iPhone. Is this some type of overlay?

I've been looking everywhere for this solution but maybe I've just got the wrong terminology. Thank you in advance.

In essence, there are a number of ways, but you have to program this effect manually. A textfield is already an overlay. You can either move it, or scroll the containing view.
