title: iPhone UITableView missing disclosure-button after pressing Delete Button when reusing UITableViewCell
body: <p>I've got an iPhone <code>UITableView</code> displaying custom <code>UITableViewCell</code>s that display on their right the disclosure-button icon.<br>
  When I swipe the cell, the disclosure button is automatically replaced by the red "Delete" button. If I press the "Delete" button the row is removed from the table, but then something strange happens.<br>
  When I scroll the table and the deleted cell is <strong>reused</strong> the data are correctly loaded but the <strong>disclosure button is missing</strong>.</p>
  
  <p>I've tried to reset the button in the <code>prepareForReuse</code> method but without success.<br></p>
  
  <p>I don't understand what I'm missing, because the behaviour seems the same of the Mail application so it should be natively supported by the iPhone OS.</p>
  
  <p>BTW: The <code>UITableViewCell</code> is loaded from a NIB.</p>
