Swift - How dynamically fixed UITableViewHeaderFooterView height size?

Question

I have just tried below lines of code, but I doesn't work correctly. I wonder that how can I provide this case for header or footer programmatically, may be using autolayout I don't know exactly which one solved my problem. I'm using xib file both of UITableViewHeaderFooterView.

If someone explain I would be great.

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    // Dynamic sizing for the footer view
    if let footerView = tableView.tableFooterView {
        let height = footerView.systemLayoutSizeFittingSize(UILayoutFittingCompressedSize).height
        var footerFrame = footerView.frame

        if height != footerFrame.size.height {
            footerFrame.size.height = height
            footerView.frame = footerFrame
            tableView.tableFooterView = footerView
        }
    }

}

Did you try this code in viewWillLayoutSubviews? – srvv Jun 11 '16 at 08:37 — srvv, Jun 11 '16 at 08:37

The UITableView calculates the HeaderFooter before they displayed, you can't update that height without calling reloadData() again.

Have you tried to use AutoLayout on those HeaderFooterViews? I would set up the view from xib with the right constraint, and then:

self.tableView.estimatedSectionHeaderHeight = 100
self.tableView.sectionHeaderHeight = UITableViewAutomaticDimension

IOS 8 can't be implemented – ChildrenGreens Jul 07 '17 at 04:32
@ChildrenGreens what do you mean by that? – orxelm Jul 08 '17 at 08:07
iOS8 constraint conflict，iOS9、iOS10 can be displayed properly – ChildrenGreens Jul 08 '17 at 08:11
Sounds like you have different problem there, check you constraints.. It's supports iOS7+ – orxelm Jul 08 '17 at 11:48

do define the data source functions ``tableView:estimatedHeightForHeaderInSection`` and ``tableView:heightForHeaderInSection`` instead of defining at viewDidLoad. – Keith Yeoh Feb 08 '18 at 06:09
