title: Specify images for iPad in Xcode like @2x for iPhone 4
body: <p>I have upgraded my current target to iPad and made a universal app and the time for adjusting my iphone app to ipad would decrease significantly if there is an answer for this question.</p>
  
  <p>By this time everybody know that if you have a image called "<em>football.png</em>" and want support for Retina Display you should double the size of the image and call it "<em>football@2x.png</em>".</p>
  
  <p>My question is if there is something for iPad like *football@iPad_which_is_another_size.png*?</p>
  
  <p>If there isn't a way to do this, do I have to connect every image to an IBOutlet and set the frame programmatically?</p>
