How to change height of view in tableview header?

I have a tableView header. I put a view and several items in. However, when a button is tapped, some objects in the view are hidden so that the view doesn't contain it as well anymore: enter image description here

enter image description here

How would I change the view height to match the items in the view?

Try dynamically sizing the headerview by overriding viewDidLayoutSubviews() and see if that works :)

    override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    // Dynamic sizing for the header view
    if let headerView = tableView.tableHeaderView {
        let height = headerView.systemLayoutSizeFitting(UILayoutFittingCompressedSize).height
        var headerFrame = headerView.frame

        // If we don't have this check, viewDidLayoutSubviews() will get
        // repeatedly, causing the app to hang.
        if height != headerFrame.size.height {
            headerFrame.size.height = height
            headerView.frame = headerFrame
            tableView.tableHeaderView = headerView
        }
    }
}

Implementing this delegate function can help you... 

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return Your_View.frame.height Or Others
}

You need to set the sectionHeaderHeight property in viewDidLoad. You will need to have tableView reference if you are using storyboard unless if your ViewCOntroller is of type TableViewController then just use below code.

 # Set the Header height to 50 points
 tableView.sectionHeaderHeight = 50
