title: Adding a background image to UIScrollView
body: <p>I have a <code>UIScrollView</code> added to a UIView. Now i have added a background image to the scrollVIew.</p>
  
  <p>The image has a fixed size like 320X460. But when the scroll view scrolls further down i can see white colour areas on the scroll view.</p>
  
  <p>How could i prevent this ?</p>
  
  <p>I tried adding the image to the view, and making the scrollview background as clearColor, but it doesn't work.</p>
  
  <pre><code>[scrollView addSubView:imageView];
  
  self.view = scrollview;
  
  [scrollview setBackgroundColor:[UIColor clearColor]];
  </code></pre>
