iphone - UIScrollView won't scroll!

In IB I have my UIView. Then I have a sub-UIView with a UIScrollView as a sub view. Then the UIScrollView has a sub-UIImageView. The UIScrollView and UIImageView are the same size. They're much bigger than the UIView of which they are subviews. I assumed this would make scrolling work. It doesn't. Is some sort of code required for scroll views to work?

You need to set UIScrollView.contentSize to match the total scrollable size, which is your subview frame size in this case.
