Example Usage: 

// Customize the appearance of table view cells.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
       cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    }

  NSDate *object = _objects[indexPath.row];

  cell.textLabel.text = [object description];
  NSInteger numberOfSections = [self numberOfSectionsInTableView:tableView];
  NSInteger numberOfRows = [self tableView:tableView numberOfRowsInSection:(numberOfSections-1)];

  if (indexPath.section == (numberOfSections - 1) && indexPath.row == (numberOfRows-1))
    [cell addDropShadow];
  else
   [cell removeDropShadow];

  return cell;
}

- (void)viewWillAppear:(BOOL)animated

{
  NSInteger numberOfSections = [self numberOfSectionsInTableView:self.tableView];
  NSInteger numberOfRows = [self tableView:self.tableView numberOfRowsInSection:(numberOfSections-1)];
  NSIndexPath *indexPath = [NSIndexPath indexPathForRow:(numberOfRows -1) inSection:(numberOfSections-1)];
  UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
  [cell addDropShadow];
}
