iOS 使用 Alamofire 实时监测网络状况

最近在用Swift写工程,,网络请求用的是Alamofire,在翻看这个库的时候发现 NetworkReachabilityManager 可以进行网络监察,废话不多说直接上代码吧,有兴趣的朋友可以去深入研究(https://github.com/Alamofire/Alamofire.git)

let manager = NetworkReachabilityManager(host: "https://github.com/Alamofire/Alamofire.git")    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {        // Override point for customization after application launch.        manager!.listener = { status in                        switch status {            case .notReachable:                print("notReachable")            case .unknown:                print("unknown")            case .reachable(.ethernetOrWiFi):                print("ethernetOrWiFi")            case .reachable(.wwan):                print("wwan")                            }        }        manager!.startListening()        return true    }
