如何实现动态可滚动按钮菜单？

Question

我已经在滚动视图中创建了动态按钮，但我需要这样做。

当我点击按钮时，我不想更改视图控制器只获取同一视图控制器上的按钮标题。我尝试了以下方式在scrollview中创建按钮。

class ViewController: UIViewController {

@IBOutlet weak var productScrollView: UIScrollView!
 var buttonValues = ["Equity","Commodity","Derivatives","Market","Products","Values"]
override func viewDidLoad() {
    super.viewDidLoad()

    let scrollingView = colorButtonsView(buttonSize: CGSize(width:100.0,height:30.0), buttonCount: buttonValues.count)
    productScrollView.contentSize = scrollingView.frame.size
    productScrollView.addSubview(scrollingView)
    productScrollView.showsHorizontalScrollIndicator = false
    productScrollView.indicatorStyle = .default
    productScrollView.setContentOffset(.zero, animated: false)
    // Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

func colorButtonsView(buttonSize:CGSize, buttonCount:Int) -> UIView {
    //creates color buttons in a UIView
    let buttonView = UIView()
    buttonView.backgroundColor = UIColor.white
    buttonView.frame.origin = CGPoint(x:0,y:0)
    let padding = CGSize(width:10,height:10)
    buttonView.frame.size.width = (buttonSize.width + padding.width) * CGFloat(buttonCount)
    buttonView.frame.size.height = (buttonSize.height +  2.0 * padding.height)
    var buttonPosition = CGPoint(x:padding.width * 0.5,y: padding.height)
    let buttonIncrement = buttonSize.width + padding.width


    for i in 0...(buttonCount - 1)  {
        let button = UIButton(type: .custom) as UIButton
        button.frame.size = buttonSize
        button.frame.origin = buttonPosition
        buttonPosition.x = buttonPosition.x + buttonIncrement
        button.setTitle(buttonValues[i], for: .normal)
        button.setTitleColor(UIColor.black, for: .normal)
        button.layer.borderWidth = 1
        button.layer.borderColor = UIColor.black.cgColor
        button.addTarget(self, action: #selector(colorButtonPressed(sender:)), for: .touchUpInside)
        buttonView.addSubview(button)

    }
    return buttonView
}

@objc func colorButtonPressed(sender:UIButton!){
    print(sender.title(for: .normal)!)
    sender.setTitleColor(UIColor.blue, for: .normal)

}}
