title: Cycle images in a UIScrollView
body: <p>I have some images in an array and I add the images onto a scroll view, but I want to show only 3 images on the screen at any given time. The screen has arrows on both sides with 3 images in the middle and upon clicking the arrow, the next image replaces the third image, the third image replaces the second, the second replaces the first and the first leaves the screen.</p>
  
  <p>Any help will be appreciated. Thanks in advance.</p>
