title: How to subclass UIApplication?
body: <p>The iPhone Reference Libary - UIApplication says I can subclass UIApplication, but if I try this I will get an exception:</p>
  
  <pre><code>*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'There can only be one UIApplication instance.'
  </code></pre>
  
  <p>This reminds me of the Highlander "There can be only one,. :-)</p>
  
  <p>Do I have to pass other argurments to UIApplicationMain? Or did I missread  somthing in the libary?</p>
