接下來先設定silder的滑直(0~255)，如果不設定的話只有(0~1)之間的滑動，並把三個滑動的值設定給UIColor

 @IBAction func SliderSum(_ sender: UISlider){
        palatte.backgroundColor = UIColor(
            red: CGFloat(redSlider.value / 255),
            green: CGFloat(greenSlider.value / 255),
            blue: CGFloat(blueSlider.value / 255),
            alpha: 1
        )
  }

並且將slider的值即時的顯示在text field裡

@IBAction func SliderToText(_ sender: UISlider){
        redValue.text = "\(Int(redSlider.value))"
        greenValue.text = "\(Int(greenSlider.value))"
        blueValue.text = "\(Int(blueSlider.value))"
    }

完成了slider 的部分接下來輪到text field的部分
先完成text field 輸入改變顏色

 @IBAction func textsum(_sender: Any){
        if let redv = Double( redValue.text ?? ""),
           let greenv = Double(greenValue.text ?? ""),
           let bluev = Double(blueValue.text ?? "") {
            
            let intRed = Int(redv)
            let intBlue = Int(bluev)
            let intGreen = Int(greenv)
            
            redValue.text = "\(String(intRed / 256))"
            greenValue.text = "\(String(intGreen / 256))"
            blueValue.text = "\(String(intBlue / 256))"
            
            palatte.backgroundColor = UIColor(
                red: CGFloat( (redv)/255),green: CGFloat( (greenv)/255),blue: CGFloat ((bluev)/255),alpha: 1)
        }

今天進度先到已經完成70%，剩下一些小細節修正
