Question

这会创建按钮：

var Todaybutton = UIButton(frame: CGRect(x: 0, y: 10, width: view.frame.size.width/7, height: 44))

Todaybutton.setTitle(dayString + "\n\(dayOfWeekString)", for: UIControlState())
Todaybutton.titleLabel?.font = UIFont.boldSystemFont(ofSize: 14.0)
Todaybutton.setTitleColor(UIColor(red: 197/255, green: 197/255, blue: 197/255, alpha: 1.0), for: UIControlState())
Todaybutton.titleLabel!.lineBreakMode = .byWordWrapping;
Todaybutton.titleLabel!.numberOfLines = 2
Todaybutton.titleLabel!.textAlignment = .center
Todaybutton.titleLabel?.font = UIFont(name: "Geomanist-Regular", size: 14.0)!
Todaybutton.addTarget(self, action: #selector(Home.onTodayButtonClicked),for: UIControlEvents.touchUpInside)
self.view.addSubview(Todaybutton)

以及按钮操作：

 func onTodayButtonClicked(_ sender: UIButton) {
    print("button works")
    showHUD()
    searchTxt.text = ""

    sender.setTitleColor(UIColor.black, for: .normal)

    Tombutton?.setTitleColor(UIColor(red: 197/255, green: 197/255, blue: 197/255, alpha: 1.0), for: .disabled)
    TwoDaysbutton?.setTitleColor(UIColor(red: 197/255, green: 197/255, blue: 197/255, alpha: 1.0), for: .disabled)
    ThreeDaysButton?.setTitleColor(UIColor(red: 197/255, green: 197/255, blue: 197/255, alpha: 1.0), for: .highlighted)
    FourDaysButton?.setTitleColor(UIColor(red: 197/255, green: 197/255, blue: 197/255, alpha: 1.0), for: .reserved)
    FiveDaysButton?.setTitleColor(UIColor(red: 197/255, green: 197/255, blue: 197/255, alpha: 1.0), for: .selected)
    SixDaysButton?.setTitleColor(UIColor(red: 197/255, green: 197/255, blue: 197/255, alpha: 1.0), for: .normal)

代码sender.setTitleColor（UIColor.black，for：.normal）工作并使按钮文本变黑，但是当点击另一个按钮时它不会变回197/255。我怎么做？

我有按钮我试图更改titleColor但我无法在点击另一个按钮时将其更改为默认颜色
