Hello,

The problem that I'm having is that if I press the Back button on the form

What Apple does with their interfaces is to make these kind of UIs be
modal.   That means that you do not have a back button, and instead you
provide a "Cancel" on the left, and a "Done" on the right.

Instead of "pushing" the UI, you should present your view controller in
modal mode.
