Keeping the keyboard from obscuring widgets in a form

Question

In an iPhone app, how do I keep the software keyboard from obscuring buttons, or UITextView fields in a View?

I've got the following layout:

View -\
     UITextView
     UIButton

... but, the keyboard obscures the button at the bottom when I'm typing in the UITextView. I tried using the following:

View -\
     UIScrollView -\
         UITextView
         UIButton

... but, the window does not scroll as expected, so the user has no way of clicking the button.

How is this normally handled?

Note: I do not want to scroll down automatically to make the button visible. I just want the user to be able to scroll down when they are done typing.

Answer 1

You manually set the coordinates of the controls when the keyboard appears and disappears. Or you use a UIScrollView and manually set the scroll offset.

Answer 2

You should tell the UIScrollView scrollTo... and you must figure out how far to scroll based on what input field was selected that caused the keyboard to appear.
