如果在tableview中选中复选框，如何保存选定的数组

Question

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return arraylist.count
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 50.0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
var cell = PopupCellTableViewCell()
cell  = (tableView.dequeueReusableCell(withIdentifier: "advnccell", for: indexPath) as? PopupCellTableViewCell)!
cell.bgView = Utilities().viewborder(vw: cell.bgView )
let dict = arraylist[indexPath.row] as! NSDictionary
let cd  = dict.value(forKey: "Code") as? String ?? ""
let desc  = dict.value(forKey: "Description") as? String ?? ""
cell.tittleLbl.text = cd + " - " + desc
if selectedRows.contains(indexPath)
{
cell.checkBtn.setImage(UIImage(named:"check"), for: .normal)
}
else
{
cell.checkBtn.setImage(UIImage(named:"uncheck"), for: .normal)
}
if (cell.checkBtn.currentImage?.isEqual(UIImage(named: "check")))!
{
UserDefaults.standard.set(cell.tittleLbl.text, forKey: "tittle")
}
cell.btnAction.tag = indexPath.row
cell.btnAction.addTarget(self, action: #selector(checkBoxSelection(_:)), for: .touchUpInside)
return cell
}

// checkbox selection
@objc func checkBoxSelection(_ sender:UIButton)
{
let selectedIndexPath = IndexPath(row: sender.tag, section: 0)
if self.selectedRows.contains(selectedIndexPath)
{
self.selectedRows.remove(at: self.selectedRows.index(of: selectedIndexPath)!)
}
else
{
self.selectedRows.append(selectedIndexPath)
}
self.tableVw.reloadData()
}

目前我只得到一个值，如果我选择了多个检查按钮，我怎么能得到

修复代码的这一部分：

if selectedRows.contains(indexPath)
{
cell.checkBtn.setImage(UIImage(named:"check"), for: .normal)
UserDefaults.standard.set(cell.tittleLbl.text, forKey: "tittle")
}
else
{
cell.checkBtn.setImage(UIImage(named:"uncheck"), for: .normal)
}
