title: Circular UIScrollView
body: <p>I have a <code>UIScrollView</code> with images in it. When the user reaches the last image and swipes the finger for next image, I want to show the first image. Similarly, when the user is at the first image and swipes for previous image, I want to show the last image. In short, it will be a circular sort of a thing.</p>
  
  <p>How can I implement this?</p>
