I have a scroll view that is the width of the screen but only about 70 pixels high. It contains many 50 x 50 icons (with space around them) that I want the user to be able to choose from. But I always want the scroll view to behave in a paged manner, always stopping with an icon in the exact center.
If the icons were the width of the screen this wouldn't be a problem because the UIScrollView's paging would take care of it. But because my little icons are much less than the content size, it doesn't work.
I've seen this behavior before in an app call AllRecipes. I just don't know how to do it.
How do I get paging on a per-icon sized basis to work?
Try making your scrollview less than the size of the screen (width-wise), but uncheck the "Clip Subviews" checkbox in IB. Then, overlay a transparent, userInteractionEnabled = NO view on top of it (at full width), which overrides hitTest:withEvent: to return your scroll view. That should give you what you're looking for. See this answer for more details.
