用自定义颜色扩展UIColor是真的吗？ [英] Extension for UIColor with custom colors it is real?

问题描述

我的应用程序有一些自定义颜色，现在它像字典一样保存，但我认为这不是一个好主意，我想用自定义颜色对UIColor进行扩展。

I have some custom colors for my application and now its saves like a dictionary, but I think this is no really good idea and I want to do extension for UIColor with a custom color.

这可能看起来像这样

var newColor = UIColor.MyColor // like UIColor.white

也许我应该用扩展名添加我的颜色枚举？

Maybe I should add to extension an enumeration with my colors?

推荐答案

在UIColor扩展中创建类属性

Create class property in UIColor extension

extension UIColor
{
  class var themeColor:UIColor {
    return UIColor(red: 210.0/255.0, green: 105.0/255.0, blue: 130.0/255.0, alpha: 1.0)
  }
}

OR

extension UIColor {
  static let themeColor = UIColor(red: 210.0/255.0, green: 105.0/255.0, blue: 130.0/255.0, alpha: 1.0)
}

用法

self.view.backgroundColor = UIColor.themeColor
