Question

I am trying to implement a filmstrip-like UIScrollView that will be populated with thumbnails of catalog pages. Selecting a thumbnail image will cause the main UIScrollView to move to the selected page. The Catalog may contain 100 – 200 pages, and I want to load them lazily only when required.

I have done this in a UIScrollView with paging enabled, but haven’t seen anything on the best way to do this in a non-paging scenario. There will be 6 thumbnails visible in the UIScrollView (+ 1 when the view is being scrolled) at any one time. I want to dequeue and reuse the thumbnail’s UIView when the view is scrolled, as I am doing in the main UIScrollView (which is a paging scroll view).

Thanks –

Check out the scrollview suite sample code from apple. The tiled example can probably be repurposed very easily.
