See Apple's Moving Content That Is Located Under the Keyboard, or this implementation based in Calculating Area Covered by Keyboard.

Basically you have to mount your view on a UIScrollView and add a bottom content inset with the same height than the keyboard. Then scroll using setContentOffset:animated:. This is a generic solution that you can reuse.

A more simple but non generic way is, if you have enough space at the bottom of your view without editable controls, you just scroll to a fixed position for each edit box.

use the -contentoffset property of your view.
