If your tableview has multiple sections, you may try using this:

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{
    if (section == tableView.numberOfSections - 1) {
        return [UIView new];
    }
    return nil;
}

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section
{
    if (section == tableView.numberOfSections - 1) {
        return 1;
    }
    return 0;
}
