Answer 1

Implement tableView:titleForDeleteConfirmationButtonForRowAtIndexPath: in your table view delegate.

Answer 2

For the second part of the answer I did this.

if (editingStyle == UITableViewCellEditingStyleDelete) {

 UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:indexPath];

 if (selectedCell.accessoryType == UITableViewCellAccessoryNone)
 {
     selectedCell.accessoryType = UITableViewCellAccessoryCheckmark;
 }
 else 
     if (selectedCell.accessoryType == UITableViewCellAccessoryCheckmark)
     {
         selectedCell.accessoryType = UITableViewCellAccessoryNone;
     }

}   

and

- (NSString *) tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath{

UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:indexPath];

if (selectedCell.accessoryType == UITableViewCellAccessoryNone)
{

    return (@"Check");
}
else 
    if (selectedCell.accessoryType == UITableViewCellAccessoryCheckmark)
    {

        return (@"UnCheck");
    }

}
