UIScrollView enable paging after screen width goes

问题:

Here is a screenshot for a ipad application below:

This application contains a UIScrollView with several pages. Starting 3 screens, paging is enabled. Then a wider screen Screen 4 comes (There are few more pages after screen4 and before screen5 with varying width in the app.) and paging is disable there. Now i want to again start paging with the start of Screen 5. Everything works well if Screen 4 is also of width 1024 but if it is wider then enabling paging shows screen 4 and screen 5 partially.

Is it possible to enable paging from a perticular x coordinate onwards? I already have every coordinate info and for screen 4's x coordinate is there a way to start paging from there?

Or is there a way to do not disable paging but increase page size for Screen 4?
