How to resize a tableHeaderView of a UITableView?

Question

I\'m having trouble resizing a tableHeaderView. It simple doesn\'t work.

1) Create a UITableView and UIView (100 x 320 px);

2) Set the UIView as tableHeaderV

Answer 1

For swift 5 Tested code

override func viewDidLayoutSubviews() {
      super.viewDidLayoutSubviews()

        guard let headerView = self.tblProfile.tableHeaderView else {
            return
        }

        let size = headerView.systemLayoutSizeFitting(UIView.layoutFittingCompressedSize)

        if headerView.frame.size.height != size.height {
            headerView.frame.size.height = size.height
            self.tblProfile.tableHeaderView = headerView
            self.tblProfile.layoutIfNeeded()
        }
    }

Note : You need to give all subview's constraints form top, bottom, leading, trailing. So it will get whole required size.
