title: Pass integer in userInfo of NSTimer
body: <p>I'm trying to pass an integer (<code>testInt</code>) through the <code>userInfo</code> field of <code>NSTimer</code></p>
  
  <pre><code>timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(count:) userInfo:testInt repeats:YES];
  </code></pre>
  
  <p>However I'm getting an incompatible types error message.</p>
  
  <p>Does anyone know how to pass a number through to the <code>count</code> method?</p>
