iOS - iphoneX系列 - 全局配置的基本信息

 

/// 获得当前窗口
var JY_WINDOW: UIWindow? {
    get{
        if let app = UIApplication.shared.delegate as? AppDelegate {
            return app.window
        }
        return nil
    }
}

　　

//iPhoneX系列
var iphoneX_Series: Bool {
    get {

        if UIDevice.current.userInterfaceIdiom != UIUserInterfaceIdiom.phone{
            debugPrint("不是iPhone， 是 \(UIDevice.current.userInterfaceIdiom.rawValue)")
        }

        if #available(iOS 11.0, *) {
            if let bottom = JY_WINDOW?.safeAreaInsets.bottom , bottom > 0 {
                return true
            }
        } else {
            debugPrint("iOS11 之前的版本")
        }
        return false
    }
}

　　

在iOS11以后的 非iPhoneX系列， 安全区高度是电池蓝高度，一般 获取安全区高度：在非iPhoneX系列 上以 Y = 0 开始，

var JY_NAV_HEIGHT : CGFloat{
    get{
        if #available(iOS 11.0, *) ,  iphoneX_Series{
            let safeTopHeight = JY_WINDOW?.safeAreaInsets.top ?? 0
            return safeTopHeight
        }
        return 0
    }
}

　　

一些基础配置

///获取APP名称
let JY_APP_NAME = Bundle.main.infoDictionary?["CFBundleDisplayName"] as? String ?? ""

///获取APP版本号
let JY_APP_VERSION = Bundle.main.infoDictionary?["CFBundleShortVersionString"] as? String ?? ""
/// 获取手机版本号
let iPhoneSystemVersion: String = UIDevice.current.systemVersion

/// 手机机型
var iPhoneModel: String {
    get {
        var systemInfo = utsname()
        uname(&systemInfo)
        let platform = withUnsafePointer(to: &systemInfo.machine.0) { ptr in
            return String(cString: ptr)
        }
        return platform
    }
}

//FIXME:屏幕宽度
let JY_DEVICE_HEIGHT = (UIScreen.main.bounds.size.height)

//FIXME:屏幕高度
let JY_DEVICE_WIDTH = (UIScreen.main.bounds.size.width)

//FIXME: 判断是不是运行在模拟器上面
struct Platform {
    static let isSimulator: Bool = {
        var isSim = false
        #if arch(i386) || arch(x86_64)
            isSim = true
        #endif
        return isSim
    }()
}

//自适应宽高：6S位基准
func fit(_ value:CGFloat) -> CGFloat {
    return value * (JY_DEVICE_WIDTH < JY_DEVICE_HEIGHT ? JY_DEVICE_WIDTH:JY_DEVICE_HEIGHT ) / 375
}

//FIXME: 简写获取nib
func GetStoryboardVC(storyboardName:String!,vcName:String!) -> UIViewController {
    let storeboard:UIStoryboard! = UIStoryboard.init(name: storyboardName, bundle: nil)
    let vc = storeboard.instantiateViewController(withIdentifier: vcName)
    return vc
}

//FIXME: 自定义debug 模式下不打印

func DDLOG<Message>(message: Message,
              fileName: String = #file,
              methodName: String = #function,
              lineNumber: Int = #line){
    #if DEBUG
        print("\((fileName as NSString).pathComponents.last!).\(methodName)[\(lineNumber)]:\(message)")
    #endif
}
