how do i use a UIPageControl?

Solution 1:

There is an example here, and you can read the documentation here.

Try downloading and running the example, then scanning through the documentation and the source code of the example to get an idea of what it is doing and how to use it.

I found the above two links by searching google for "uipagecontrol" and "uipagecontrol example".

Solution 2:

You basically need to add a scrollView and enable pagination on it. Then add content of each page you want to show. In your case that will be images.

You can find a very descriptive tutorial to add images in page control from here http://www.raywenderlich.com/10518/how-to-use-uiscrollview-to-scroll-and-zoom-content
