title: iPhone - How to use #define in Universal app
body: <p>I'm creating universal app that runs oniphone and ipad.
  I'm using #define to create CGRect. And I want to use two different #define - one for iPhone and one for iPad.
  How can I declare them so that correct one will be picked by universal app..........</p>
  
  <p>I think I've to update little more description to avoid confusion.
  I've a WPConstants.h file where I'm declaring all the #define as below</p>
  
  <pre><code>#define PUZZLE_TOPVIEW_RECT CGRectMake(0, 0, 480, 100)
  #define PUZZLE_MIDDLEVIEW_RECT CGRectMake(0, 100, 480, 100)
  #define PUZZLE_BOTTOMVIEW_RECT CGRectMake(0, 200, 480, 100)
  </code></pre>
  
  <p>The above ones are for iphone. Similarly for iPad I want to have different #define
  How can I proceed further?</p>
