如何在UITableView中设置特定的节标题[Swift]

Question

I want to add a section header to a section of my UITableView programmatically.

I'm trying to use this code, but it adds the header to all sections. How can I make it only set the first section's header?

override func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    return "My Section header"
}

Answer 1

Do like this

override func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    if section == 0{ // <- apply condition where you wanted to show header or not.
        return "My Section header"
    }
    return nil
}

Answer 2

Use switch-case makes better code

func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
     switch section {
     case 0: return "Section 0"
     case 1: return "Section 1"
     default: return nil
     }
}

You just have to check the section is equal to one

 override func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    return (section == 1) ? "Title Header" : nil
}
