创建一个包含 3 个视图的 Storyboard，并将类设置为 ColorWell（UIButton）、ColorPicker（UIView）和 HuePicker（UIView）。使用以下代码连接 Outlets

import SwiftColorPicker

...

@IBOutlet var colorWell:ColorWell?
@IBOutlet var colorPicker:ColorPicker?
@IBOutlet var huePicker:HuePicker?

...
// Setup
pickerController = ColorPickerController(svPickerView: colorPicker!, huePickerView: huePicker!, colorWell: colorWell!)
pickerController?.color = UIColor.redColor()

// get color:
pickerController!.color

// get color updates:
pickerController?.onColorChange = {(color, finished) in
    if finished {
      self.view.backgroundColor = UIColor.whiteColor() // reset background color to white
    } else {
        self.view.backgroundColor = color // set background color to current selected color (finger is still down)
    }
}
