body: <p>How can I know the type of class of a delegate?</p>
  
  <p><code>self.delegate.isKindOfClass()</code> and <code>self.delegate.isMemberOfClass()</code> are not working.</p>
  
  <p>When I print 
  <code>println(self.delegate)</code> It prints the caller controller class. But I cant check it. </p>
