Setting tableHeaderView height dynamically

Question

My application creates a UITableViewController that contains a custom tableHeaderView which may have an arbitrary height. I\'ve been struggling with a way to set this header

Answer 1

Based on @TravMatth and @NSExceptional's answer:

For Dynamic TableView Header, with multiple line of text(No matter have or not)

My solution is:

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    if let footView = tableView.tableFooterView {
        let newSize = footView.systemLayoutSizeFitting(CGSize(width: self.view.bounds.width, height: 0))
        if newSize.height != footView.frame.size.height {
            footView.frame.size.height = newSize.height
            tableView.tableFooterView = footView
        }
    }
}

tableView.tableFooterView = footView to make sure that your tableview Header or Footer updated. And if newSize.height != footView.frame.size.height helps you not to be called this method many times
