//添加HSBColorPicker委托函数

func HSBColorColorPickerTouched(sender:HSBColorPicker, color:UIColor, point:CGPoint, state:UIGestureRecognizerState){
    // Set the background color to the selected
    //self.view.backgroundColor = color
   self.dismiss(animated: true) {
       print("Color", color)
   }
    // Set the color of the buttons accordingly
    // Remove the view if it shares the tag
    if let view = self.view.viewWithTag(colorPickerViewTag){
        view.removeFromSuperview()
    }
}

我不知道如何在十六进制字符串中获取UIcolor值

func hexStringFromColor(color: UIColor) -> String {
    let components = color.cgColor.components
    let r: CGFloat = components?[0] ?? 0.0
    let g: CGFloat = components?[1] ?? 0.0
    let b: CGFloat = components?[2] ?? 0.0



      let hexString = String.init(format: "#%02lX%02lX%02lX", lroundf(Float(r * 255)), lroundf(Float(g * 255)), lroundf(Float(b * 255)))
    print(hexString)
    return hexString
