Resolved scroll view doesn't scroll in certain area

I have a view controller that has 2 nested scroll views, one that pages side to side and one that scrolls the content vertically. Everything was working fine, but now I'm updating the app to fit the iPhone 5 screen, and now there's an area about 60 pixels high at the bottom of the screen where if I touch there, the view won't scroll vertically, but I can touch there and page side to side. I've checked, and the frame of both scroll views are exactly the same, but the vertical one won't respond to drags. This area of the screen works fine for scrolling in both directions on an iPhone 4 screen.

Any ideas why this might be?

Thanks,

 

Exactly, I've verified through debugging that both scroll views have the same frame, but the vertical scroll view doesn't respond to touches below where an iPhone 4 screen would end and I have no idea why.

 

I mean that when I detect an iPhone 5 screen, I change the frame of both scroll views, the one that scrolls vertically, and the one the scrolls horizontally. I verified that both scroll views have their frame changed to be the same height and location, yet the horizontal scroll view works fine, but the vertical scroller doesn't respond to touches near the bottom of the screen.

 

I assume the UIWindow size must be correct since all other controls respond to touch events at all locations on the screen.

 

Finally figured this out. I was correctly re-sizing the scroll view size for an iPhone 5 screen, but I neglected to re-size the view that the scroll view was a subview of.
