Swift 3 tableview header custom cell

Question

I had a custom cell being used as a tableview section header. I updated to swift 3 and now it is not showing anymore

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    let header = tableView.dequeueReusableCell(withIdentifier: "tableHeader") as! tableHeader

then i put in some constraints and return header

Answer 1

你的自定义类应该从UITableViewHeaderFooterView扩展，它会工作。

Answer 2

I know it's a late answer but for some who did not find the correct answer till. You can use UITableViewSectionHeight. Below is an example:

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    return 80 // this is your row height
 }
