Answer 1

Apple has an example project featuring infinite scrolling it’s called StreetScroller, which demonstrates how a UIScrollView subclass can scroll infinitely in the horizontal direction.
There is also an UIScrollView subclass on Github called BAGPagingScrollView, which is paging & infinite, but it has a few bugs you have to fix on your own, because it’s not under active development (especially the goToPage: method leads to problems).
I hope this helps you.

Also check this link for easy implementation they also have a sample code attached 🙂
