How to remove vertical spacing between sections of a UITableView?

I have a grouped table view with several partitions. By default, there is a gap between sections. I was looking for an easy way to completely remove the gap without any luck. The best I could do with Interface Builder is to set the "Section Height" values ​​in the "Table Size" properties section, but these fields do not accept 0 as valid input. Can someone tell me the best way to figure this out?

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
    return 0.0;
}

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
