Get last cell in a UITableview section

I have a section in UITableView which has multiple rows. I wish to get the last row or the last cell of the section to add a disclosure indicator on it.

One way I am thinking to use is:

NSIndexPath *lastCellIndexPath = [NSIndexPath indexPathForItem:[self.tableView numberOfRowsInSection:2]-1 inSection:2];

Is there any other best way to get the cell or indexpath of the last cell on a section?

    NSInteger totalRow = [tableView numberOfRowsInSection:indexPath.section];//first get total rows in that section by current indexPath.
    if(indexPath.row == totalRow -1){
         //this is the last row in section.
    }

hope it helps.

I did this in tableView:willDisplayCell:forRowAtIndexPath: method

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath;
