UITableView heightForHeaderInSection not working

Question

I have a simple UITableView (sample project here) but the section headers do not respect the height I'm setting in the heightForHeaderInSection

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    return 40;
} 

The table view looks like this. The 1 section header has a correct height but not the other ones.

When I inspect the view with the Reveal app, it seems that there is a kind of footer after the last cell in the section.

What am I doing wrong?

Answer 1

What seems to work is this

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
    return 0.0001f; // 0.0f does not work
}

or even better, in loadView

self.tableView.sectionFooterHeight = 0.0f;

Answer 2

Swift:

Swift version of approved answer:

override func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
    return CGFloat.leastNonzeroMagnitude
}
