如何在 swift 中动态创建堆栈视图？

Question

您好，我为四个堆栈视图开发了一个程序，用于在同一视图中添加另一个堆栈，我需要另一个子视图，有没有其他方法可以使用 for 循环添加子视图，我是 swift 语言的新手和学习，需要帮助

如何将所有堆栈视图保留在 for 循环中以便我可以添加 n 个堆栈视图

这是使用 UIStackViews 构建键盘的代码片段...

func newPad() {
    keyPadWindow = UIView(frame: CGRect(x: 128, y: 224, width: 512, height: 356))
    keyPadWindow.backgroundColor  = UIColor.yellowColor()
    var keyCount = 0
    keyPadSV = UIStackView(frame: CGRect(x: 0, y: 0, width: 512, height: 356))
    keyPadSV!.axis = .Vertical
    keyPadSV!.spacing = 0.0
    keyPadSV!.alignment = .Center
    keyPadSV!.distribution = .EqualSpacing
    keyPadSV!.backgroundColor = UIColor.redColor()
    for var k2s = 0; k2s < 5; k2s++ {
        let keyPadSVB = UIStackView(frame:CGRect(x: 0, y: 0, width: 0, height: 0))
        keyPadSVB.axis = .Horizontal
        keyPadSVB.spacing = 0.0
        keyPadSVB.alignment = .Center
        keyPadSVB.distribution = .EqualSpacing
        keyPadSVB.backgroundColor = UIColor.greenColor()
        for var k4s = 0; k4s < 4; k4s++ {
            let button   = UIButton(type: UIButtonType.Custom) as UIButton
            button.frame = CGRectMake(0, 0, 0, 0)
            button.backgroundColor = UIColor.greenColor()
            button.tag =  keyCount
            let blah = "x" + String(keyCount)
            let blahIMAGE = UIImage(named: blah)
            button.setImage(blahIMAGE, forState: UIControlState.Normal)
            button.addTarget(self, action: "keyPadPress:", forControlEvents: UIControlEvents.TouchUpInside)
            keyPadSVB.addArrangedSubview(button)
            keyCount++
        }
        keyPadSV.addArrangedSubview(keyPadSVB)
    }
    keyPadWindow.addSubview(keyPadSV)
    self.view.addSubview(keyPadWindow)
}

这取决于你有 16 张图像来显示键。
