title: Hiding UITableView footer
body: <p>I am unable to hide my UITableView footer (i.e. setting it's height to 0 and animating the transition).</p>
  
  <p>I tried to wrap <code>tableView.tableViewFooter.height = 0</code> (and <code>tableView.tableViewFooter = nil</code>) between <code>[tableView beginUpdates]</code> and <code>[tableView endUpdates]</code> but it doesn't work.</p>
  
  <p>Implementing the method below creates another footer.</p>
  
  <pre><code>- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section
  {
      return 50;
  }
  </code></pre>

  <p>Is there a difference between a tableview footer and a section footer? I created mine by dropping a button under my tableview in my storyboard.</p>
  
  <p>Any ideas to do this simply?</p>
