I've been looking into using the UIPageControl for a scrolling part of an application, and I was wondering how it works. The docs show methods for changing pages, setting the number of pages etc., but by itself the page control doesn't encompass any kind of scroll view.
Are the UIPageControl and UIScrollView classes supposed to be used in conjunction when one wants to show the page indicator (like on the home screen of the iPhone with the app pages)?
The paging bit is actually done by setting the paging property on the UIScrollView. The page control is simply a useful UI construct, but doesn't actually do anything to do with paging itself.
