title: NSUInteger to int
body: <p>I wrote a method tha uses myarray, defined in the same class. When I use count it always returns 0.
  When I use:</p>
  
  <pre><code>printf("%d", [myarray count]);
  </code></pre>
  
  <p>compiler says:</p>
  
  <pre><code>Format '%d' expetcs type 'int', but argument 2 has type 'NSUInteger'
  </code></pre>
  
  <p>why?</p>
