title: Why [super class] and [self class] produce the same result?
body: <pre><code>-(NSString *) nibName
  {
      PO([self class]);
      PO([super class]);
      PO([self superclass]);
  </code></pre>
  
  <p>Only the <code>[self superclass]</code> produces the actual super class.</p>
  
  <pre><code>[self class]: BGImageForBizs
  [super class]: BGImageForBizs
  [self superclass]: BGUIImageWithActivityIndicator
  </code></pre>
