Scrolling a horizontal UIScrollView in stepped increments?

Question

I have a UIScrollView that can be scrolled horizontally. The scrollable content is displayed in columns.

Is there a way to make the scrolling only move in stepped in

If you target iOS 5.0, you can use the new UIScrollViewDelegate method scrollViewWillEndDragging:withVelocity:targetContentOffset. This allows you to set the point where the scrolling animation will end after the user has stopped dragging the scroll view.
