swift - 网络连接

1. pod install

 use_frameworks!

 pod 'ReachabilitySwift'

2. build error...

3. Just put the Reachability.swift file in my product.

// 网络状态监听

    let reachability = Reachability()!

    func reachabilityChanged(note: Notification) {

        

        let reachability = note.object as! Reachability

        

        switch reachability.connection {

        case .wifi:

            print("Reachable via WiFi");

            if(mLoadWebViewStackSize == 0)

            {

                //reloadData();

            }

        case .cellular:

            print("Reachable via Cellular");

            if(mLoadWebViewStackSize == 0)

            {

                //reloadData();

            }

        case .none:

            //alert_noNetwrok();

            print("Network not reachable")

        }

    }

// 移除消息通知

    deinit {

        reachability.stopNotifier();

        NotificationCenter.default.removeObserver(self, name: .reachabilityChanged, object: reachability);

    }

override func viewWillAppear(_ animated: Bool) {

        super.viewWillAppear(animated);

        

        

        NotificationCenter.default.addObserver(

            self,

            selector: #selector(self.reachabilityChanged),

            name: .reachabilityChanged,

            object: reachability

        )

        

        do {

            try reachability.startNotifier()

        } catch {

            print("could not start reachability notifier")

        }

    }
