title: proper way to set background image to IPad App
body: <p>I have a working IPad App. I built everything on a default white screen and I want to add an image to background of the image. I read a couple of articles and most of the suggest to create a new UIImage with the background image and stretch it to the full screen. I tried that but I am using a couple UIImage to display the photos taken and my UIImage s seem to stay at the  back of the background and they don't get shown. </p>
  
  <p>What is the proper way to set the background of IPad App?</p>
  
  <p>this is the screenshot of my IPad App</p>
