iphone - UIScrollView won't scroll!

Question

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?

Answer 1

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