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?

Overview. UIScrollView is the superclass of several UIKit classes, including UITableView and UITextView . A scroll view is a view with an origin that's adjustable over the content view. It clips the content to its frame, which generally (but not necessarily) coincides with that of the app's main window.
Scroll Views in combination with paging enabled allows the user to scroll page by page. In this tutorial we will create some views, which can be scrolled using paging. This tutorial is made with Xcode 10 and built for iOS 12. Open Xcode and create a new Single View App.
You cannot make a UIView scrollable. That's what UIScrollView is for. However if you are using storyboards you can try to add constraints to the view so when you rotate the device the content remains inside the viewable area.
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.
