title: Iterate over all the UITableCells given a section id
body: <p>Using Swift, how can I iterate over all the <code>UITableCells</code> given a section id (eg: all cells in section 2)?</p>
  
  <p>I only see this method: <code>tableView.cellForRowAtIndexPath</code>, which returns 1 cell given the absolute index, so it doesn't help.</p>
  
  <p>Is there an elegant and easy way?</p>
  
  <p>Note: I want to set the AccesoryType to None for all of the cells in a section, <strong>programatically</strong>, say: after a button is clicked, or after something happends (what happends is not relevant for the question)</p>
  
  <p>I have the reference for the UITableView and the index of the section.</p>
