如何快速冻结tableView单元格？

Question

I want to freeze a tableView cell on top of screen, so that while scrolling, other cells move but the top cell stays on its place.

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "myCell", for: indexPath)
        cell. //I think it must be here
        return cell

Thank you.

try this:

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    return 65
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    let header = view as! UITableViewHeaderFooterView
    header.textLabel?.textColor = UIColor.black
header.textLabel?.text="adadafaf"//ur data
}

Use these methods to create tableview header and add any subviews in it.

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    return 50
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    let header = UIView.init()
    header.backgroundColor = UIColor.gray
    //Add subviews here
    return header
}
