将自定义UIColor引入Swift项目的最佳方法是什么？ [英] What is the best way to introduce a custom UIColor to a Swift project?

问题描述

我想过两种类型的实现;在性能，可读性和可维护性方面，您认为其中哪一个更好？

I've thought of two types of implementation; which one of them is better in your opinion in terms of performance, readability and maintainability?

1. 创建UIColor的扩展名，如下所示

1. Create an extension of UIColor like this

extension UIColor {
    class func myColor() -> UIColor {
        return UIColor(red: 128/255, green: 102/255, blue: 0, alpha: 1)
    }
}

创建结构：

Create a structure:

struct Colors {
    static let myColor = UIColor(red: 255/255, green: 102/255, blue: 0, alpha: 1)
}

推荐答案

答案：扩展，在我的专业意见。

Answer: Extension, in my professional opinion.

考虑一下;在哲学上，你是扩展 UIColor 提供的颜色范围。如果您的颜色名称是不同的，并且新功能遵循Apple的方法命名协议（即<颜色名称>颜色），则扩展 UIColor 看起来更整洁。一个或两个新颜色（在我看来）不保证整个专用的结构。

Think about it; you are, in philosophy, 'extending' the range of colors offered by UIColor. Provided that your color name is distinct and the new function follows Apple's method naming protocol (i.e. <color name>Color), extending UIColor seems neater. One or two new colors (in my opinion) don't warrant an entire dedicated struct.

奖励回答：
struct （或 enum ！）是不是很合适？

Bonus answer: Where would a struct (or enum!) be a good fit?

• 如果您的应用强制替换标准颜色（即自定义
  ） '主要'颜色）


• 如果您的应用专门设计为主题/自定义，那么可能有一个枚举，作为可用选项的具体列表。


• 如果你想不出颜色的标准名称（ sharkBlueColor ，有人吗？）。


• 如果您的应用专门用于绘图/绘画（在这种情况下，调色板构造可能是个好主意）。

• If your app forces replacements for the standard colors (i.e. custom 'primary' colors)
• If your app is specifically designed to be themed / customized, it might be good have an enum, to serve as a concrete list for available options.
• If you can't think of standard names for the colors (sharkBlueColor, anyone?).
• If your app is specifically for drawing/painting (in which case a 'palette' construct might be good idea).

......列表还在继续。当你成熟为Swift开发者时，你必须学会​​辨别和决定自己！

... the list goes on. You must learn to discern and decide for yourself as you mature as a Swift developer!
