title: Delete section (red delete button), UITableViewController - iOS
body: <p><br>
  I'm trying to do a grouped uitableview and I have activated the edit option. I want the user to be able to delete the whole section too, not only specific rows.<br>
  So, when you click EDIT, the red minus button that shows on the left of each table cell, should show up for sections (left of the section title) too.<br>
  Anyone knows a way to do this?  </p>
  
  <p>Thanks in advance to everyone!<br>
