Detecting UIScrollView page change

Question

Is there a way to detect or get a notification when user changes the page in a paging-enabled UIScrollView?

Answer 1

In paging enabled scroll view you can use scrollViewDidEndDecelerating to know when the view is settled on a page (might be the same page).

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView

scrollViewDidScroll gets called on every movement. And in context of paging enabled view can be used to find when it is scrolled enough to move to next page (if dragging is stopped at that point).
