Space Between Sections in UITableview

Question

I need to reduce the space between two sections ofUITableView. I looked at this question but the solution doesn\'t allow for my custom header view because it c

Answer 1

For Swift 5+:

There is some space for the headers and footers by default. That's why I was having the problem of setting an exact separation for the sections.

My solution to have a separation between 2 sections is the following:

override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {

        if section == 0 {
             return 24
        } else if section == 1 {
             return 32
        }
    }

    override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
        nil
    }

    override func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
        nil
    }

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

As you see for viewForFooterInSection and viewForHeaderInSection I needed to return nil.

In case you only want to change the footerHeight, just return CGFloat.leastNormalMagnitude for heightForHeaderInSection, and return the heights for each section in heightForFooterInSection.
