iPhone – Keyboard hides TextField

I am using UITextField to receive user inputs. However, since my textfields are towards the middle/bottom of the nib, it gets hidden when the keyboard pops up. Is there any way sort of slide it along with the keyboard so that it’s on the top of the keyboard during selection? Also, since I am also using the numberpad, is there an easy way to include a done button somewhere?

Thanks for the help.
