title: How to programmatically set the current page for UIPageControl?
body: <p>I have 3 "pages" (page 0, page 1, page 2) in a UIScrollView that are snapped to by finger swipes. There is a UIPageControl there too. The UIScrollView starts off presenting page 0. What I want to do is present page 3 FIRST sometimes. How can I do this programmatically. </p>
  
  <p>Simply setting currentPage (of UIPageControl) to the page number does nothing by the way.</p>
