title: UITableView - Section header. How to change text?
body: <p>I have a project which uses Storyboards. I have a UITableView with Static cells and Group style.</p>
  
  <p>I need to change the section text in one section depending on which selection is made in a segmented control (in another section)</p>
  
  <p>I have found some solutions which indicate that you should use override this method:
  <br> 
  <code>
  - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
  </code></p>
  
  <p>and trigger an update by calling:<br>
  <code>
  [[self tableView]reloadSections:[NSIndexSet indexSetWithIndex:SectionToChange] withRowAnimation:UITableViewRowAnimationFade];
  </code></p>
  
  <p>The problem is when I call reloadSections then all the rows and cells in the section in question get deleted. The text updates correctly thought but with this unwanted side effect.</p>
