Changing background color of selected cell?

Question

Does anyone know how to change the background color of a cell using UITableViewCell, for each selected cell? I created this UITableViewCell inside the code for TableView.

Answer 1

var last_selected:IndexPath!

define last_selected:IndexPath inside the class

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let cell = tableView.cellForRow(at: indexPath) as! Cell
    cell.contentView.backgroundColor = UIColor.lightGray
    cell.txt.textColor = UIColor.red

    if(last_selected != nil){
        //deselect
        let deselect_cell = tableView.cellForRow(at: last_selected) as! Cell
        deselect_cell.contentView.backgroundColor = UIColor.white
        deselect_cell.txt.textColor = UIColor.black
    }

    last_selected = indexPath
}
