How do I keep keep my view from displaying off screen in iOS7?

Question

We are updating our app to work with iOS7 and have had a lot of trouble with orientation and the placement of our views.

We are using views that display a list that goes from

Categories->Location->Location Information.

The Location and Location Information views have a back button on them to go to the previous screen. However, whenever the back button is pushed the view is being centered somewhere off screen. I know this because I have used the Reveal application (revealapp.com) to see where the views are positioned as I run it on my iPhone.

When the view is correctly positioned on screen its container views center is set at (X: 160, Y:240)

But when I push the back button the view is positioned in the opposite corner and the container views coordinates are now set to (X: 160, Y:720.)

Any idea what could be causing this?

Our UI needs to work in Landscape mode specifically and we have had all sorts of issues preserving that orientation with the iOS7 upgrade.

Any assistance or clues would be appreciated.

I'm including the script that seems to be controlling the orientation.
