title: Default height for section header in UITableView
body: <p>I want to set the height of the first header in my UITableView. For the other headers I want them to remain the default height. What value/constant can I put in place of "someDefaultHeight" in the code below?</p>
  
  <pre><code>- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
  {
      if (section == 0)
          return kFirstHeaderHeight;
  
      return someDefaultHeight;
  }
  </code></pre>
  
  <p>Thanks</p>
