title: Add rows to existing UITableView section
body: <p>I am trying to get some sample code on how I would add rows to an existing <code>UITableView</code>. I am trying to use the <code>insertRowsAtIndexPaths:</code> function.</p>
  
  <pre><code>    [tableView insertRowsAtIndexPaths:addindexes withRowAnimation:UITableViewRowAnimationTop];
  </code></pre>
  
  <p>Any ideas how these indexes work and how I can add to an existing section or, if I don't have a section, then create a new section?</p>
