swift 常用宏定义

在Swift中不需要去创建header文件，只需要创建一个类即可，什么也不用配置。下面是一些本人总结的一些常用的宏定义：

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

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

let isIPhoneX: Bool = GHEIGHT == 812 ? true : false

/// iPhone4设备

let isIPhone4 = (max(UIScreen.main.bounds.size.width, UIScreen.main.bounds.height) < 568.0 ? true : false)

/// iPhone5设备

let isIPhone5 = (max(UIScreen.main.bounds.size.width, UIScreen.main.bounds.height) == 568.0 ? true : false)

/// iPhone6设备

let isIPhone6 = (max(UIScreen.main.bounds.size.width, UIScreen.main.bounds.height) == 667.0 ? true : false)

/// iPhone6Plus设备

let isIPhone6P = (max(UIScreen.main.bounds.size.width, UIScreen.main.bounds.height) == 736.0 ? true : false)

let GetAppInfo = Bundle.main.infoDictionary//当前app信息

let GetAppCurrentVersion = Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString")//获取当前版本号

let GetSystemVersion = UIDevice.current.systemVersion//获取设备系统号

let isIphone = UIDevice.current.userInterfaceIdiom == UIUserInterfaceIdiom.phone ? true : false//iphone设备

let isIpad = UIDevice.current.userInterfaceIdiom == UIUserInterfaceIdiom.pad ? true : false//ipad设备

//rgb

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

{

return UIColor(red: (r)/255.0, green: (g)/255.0, blue: (b)/255.0, alpha: alpha)

}

//十六进制颜色

func COLORFROM16(h:Int) ->UIColor {

return COLORFROMRGB(r: CGFloat(((h)>>16) & 0xFF), CGFloat(((h)>>8) & 0xFF), CGFloat((h) & 0xFF), alpha: 1.0)
