xcode - ios8 Swift - 转换 UIColor

Question

有没有办法将 UIColor 转换为字符串？例如，

var color = UIColor.purpleColor()
var colorString : String = //Purple

如果你能帮助我，我将不胜感激。谢谢

Answer 1

可以获得颜色描述

var color = UIColor.purpleColor()
var colorString : String = color.description
println(colorString)

---

var cgColorRef = UIColor.purpleColor().CGColor
var strColor = CIColor(CGColor: cgColorRef).stringRepresentation()
println(strColor)
