Swift 创建工程常用的类方法

  let heigth = XSizeClass().iPhoneHeight(height: 80)

  let image = XAttributeClass().ImageName(name: "iamge")

import Foundation
import UIKit

//尺寸大小
class XSizeClass: NSObject {
    
    //适配高 宽
    func iPhoneHeight(height:CGFloat) -> CGFloat {
        
        return UIScreen.main.bounds.size.height * (height / 1334.0)
        
    }
    
    
    func iPhoneWidth(width:CGFloat) -> CGFloat {
        
        return UIScreen.main.bounds.size.width * (width / 750.0)
        
    }
    
    // 获取屏幕的 高宽
    func ScreeWidth() -> CGFloat {
        
        return UIScreen.main.bounds.size.width
    }
    
    func ScreenHeight() -> CGFloat {
        
        return UIScreen.main.bounds.size.height

    }
    
    //判断系统版本是不是。。。
    func iOSVersionOfString(string:String) -> Bool {

            return false
        }

}


//属性方法

    func WhiteColor() -> UIColor {
        return UIColor.white

    //图片相关
    
        //获取本地图片
    func ImageName(name:String) -> UIImage {

    }
