Question

Imagine you have a normal table view where each row is an item on a conveyor belt. You will put the items in each cell of the table view but when you scroll you also want the background image (the conveyor belt) to scroll as well. How can you do this?

Answer 1

Have the UITableView background transparent, and add a UIScrollView behind it with the UIImageView inside it. Add a listener for when the UITableView scrolls (since it is a subclass of UIScrollView it has all the same delegate methods). Then, when it scrolls, set the scroll position of the UIScrollView behind it to the same programmatically.

You could technically do it without a second UIScrollView behind the UITableView, just with a plain UIIImageView, if you want to reverse the offset values.
