title: iOS uiscrollview rotate images as the user scrolls
body: <p>I have a horizontal scrollview with an image which I need to rotate as the user scrolls left or right. It needs to rotate as the user moves the scroll across the screen. So if the user scrolls half way and stops the image should rotate halfway etc. I have looked at few examples but nothing seems to be giving me the correct result. Can some one please help.</p>
  
  <p>Thanks in advance </p>
