title: Preprocessor Directives to separate targets in xcode
body: <p>I have 2 targets on my project one production and one stage with different configurations. 
  I want in the code to be able to say</p>
  
  <pre><code>#if target == production
  NSLog(@"production");
  #elif target == stage 
  NSLog(@"stage");
  #endif
  </code></pre>
  
  <p>Can someone please tell me how can I do that?</p>
  
  <p>Thank you,</p>
