SWIFT无法获取动态视图的总数按钮单击

Question

SWIFT无法获取动态视图的总数按钮单击。

当我在一个自定义动态视图（TextField）中输入数据时，在另一个Cust-Dynamic视图（TextField）中输入数据。

我希望TextField Outside中的这两个Txt字段的总和。

有人可以帮助我使用此代码，

如果你可以在底部看到整体Sqft有总和文本字段，并且Cust-Dynamic View的数量被称为所有文本字段的总和结果需要在整体sqft TextField中更新。 例如：99 + 99 = 198.00 提前致谢。

    func viewcall()
    {
      //  for _ in 0..<count {
        myView = customSubView(frame: CGRect(x: 100, y: 220+y_value, width: 400, height: 245))
        myView.backgroundColor = UIColor(white: 1, alpha: 0.5)
        myView.layer.cornerRadius = 15
        myView.Board_height.addTarget(self, action: #selector(didChangeText(textField:)), for: .editingChanged)
        myView.actionButton.addTarget(self, action: (#selector(cancelbutton(_:))), for: UIControlEvents.touchUpInside)
        myView.NoofBoardtext.addTarget(self, action:#selector(didChangeTexts(textField:)), for: .editingChanged)
        myView.numberofdays.addTarget(self, action:#selector(dayscalculation(textField:)), for: .editingChanged)
        self.scrlview.addSubview(myView)

}
func didChangeText(textField: UITextField)
    {
        myView.Board_total.text = String(Int(myView.Board_size.text!)! * Int(myView.Board_height.text!)!)

    }
//only Calculation for total SQFT
    func didChangeTexts(textField: UITextField)
    {
        myView.totalSQFT.text = String(Int(myView.NoofBoardtext.text!)! * Int(myView.Board_total.text!)!)
    }
//only Calculation for total SQFT
    func dayscalculation(textField: UITextField)
    {
       myView.totalDays.text = myView.numberofdays.text!
       myView.Totalsqfttext.text = String(Int(myView.totalSQFT.text!)! * Int(myView.numberofdays.text!)!)
        overallSQFTtext.text = myView.Totalsqfttext.text
    }
