Question

I’m in the code design phase of a project and I am not sure if this style of scrolling custom items is available without a bit of custom code, so I’m running it by SOF to find out.

-----------------------------
|A            B            C|
|--+    +-----------+    +--|
|  |    |           |    |  |
|  |    |           |    |  |
|  |    |           |    |  |
|  |    |           |    |  |
|  |    |           |    |  |
|--+    +-----------+    +--|

Per my developer graphics, you can invision a UIScrollView with pagingEnabled. My questions is, will the UIScrollView allow me to show the edges of neighboring items when an item has claimed the center position?

Thanks in advance!

This question has popped up several times; I’ve never implemented this myself, but most of the answers seem to involve combining a few things:

• The scroll view frame should be set up as if you only wanted to show a single page, in the middle of the view.
• The scroll view needs to have it’s clipsToBounds property set to NO, so it will show the other pages.
• No user touches will get to the scroll view if the user touches the partially exposed pages, since those are now technically outside the scroll bounds, so you have to override a method on UIView to hijack the normal method of routing touches to views. The scroll view should be inside or behind this custom view.

Edit: Here’s a tutorial that describes what you’re after.
