title: Must I call super when I implement -scrollViewDidScroll: of UIScrollViewDelegate in an UITableView?
body: <p>I made a custom UITableView subclass and implemented this:</p>
  
  <pre><code>- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
      // scrolled...
  }
  </code></pre>
  
  <p>Now, what I think is that UITableView may also love to get this message for some obvious reasons. However, when I don't forward that to super, for some reason, everything still works fine. Must I forward that guy to super? I mean...it's a delegate method implementation, but as far as I'm aware of, this would still override anything implemented in UITableView, or not?</p>
  
  <p>Edit: I see...the delegate could be anyone. Never mind about this. BUT: What I have such a thing in a superclass, and make a subclass. How would I even know that the superclass does implement that method and I must forward it to super?</p>
