title: How to set background color to the content area in UIScrollView?
body: <p>I am using an <code>UIScrollView</code> in my application, my requirement is I have to add background color to the <code>UIScrollView</code> but when user drags at the extreme top or at the extreme bottom the area other than the content/out side the content which shows in the scroll view should be shown with different color just like in <code>UIWebView</code>. In web view if we drag down at the top or drap up at the bottom it will show default background image/gray color and the web view content background color is diff(default white).Can anyone help me in achieving this.</p>
  
  <p>thank you.</p>
