Swift宏定义

Swift宏定义

　　1.新建文件, 选择iOS -> Source -> Swift File

　　

　　名字你自己随心意

　　生成的会是一个.swift空文件, 默认应该会是Foundation框架, 自己修改为UIKit即可

import UIKit

let SCREEN_WIDTH =UIScreen.main.bounds.size.width

let SCREEN_HEIGHT =UIScreen.main.bounds.size.height

func RGBCOLOR(r:CGFloat,_ g:CGFloat,_ b:CGFloat) -> UIColor

{

    returnUIColor(red: (r)/255.0, green: (g)/255.0, blue: (b)/255.0, alpha: 1.0)

}
