title: iOS - NSNotificationCenter memory leak
body: <p>Instruments reports this a memory leak (98.6%, whatever that means):</p>
  
  <pre><code>[[NSNotificationCenter defaultCenter] postNotificationName:kNotificationSomeNotification object:self];
  </code></pre>
  
  <p>"self" is a subclass of UIImageView. Is including "self" in the notification causing a memory leak? If so, how do you resolve it?</p>
