Question

NetworkReachabilityManager来自Alamofire我遇到问题。我尝试使用此示例代码测试连接：

override func viewDidLoad() {
    super.viewDidLoad()

    let manager = NetworkReachabilityManager(host: "www.apple.com")

    manager?.listener = { status in

    switch status {

       case .notReachable:
          print("network connection status - lost")
      case .reachable(NetworkReachabilityManager.ConnectionType.ethernetOrWiFi):
          print("network connection status - ethernet/WiFI")
      case .reachable(NetworkReachabilityManager.ConnectionType.wwan):
          print("network connection status - wwan")
      default:
          break
    }
  } 
  manager?.startListening()
}

当我试图关闭wifi时，我只收到空白回复。没有诸如＆＃34;网络连接状态之类的响应 - 丢失＆＃34;。

但是当我试图打开wifi并且我收到了结果＆＃34;网络连接状态 - ethernet / WiFI＆＃34;其中反应良好。知道.notReachable有什么问题吗？任何建议都表示赞赏。

根据Alamofire＆＃34;确保记得留住经理＆＃34;所以创建一个像这样的经理

class A: UIViewController{

let manager = NetworkReachabilityManager(host: "www.apple.com")

override func viewDidLoad() {
super.viewDidLoad()

// before start listening you can check 
if (manager?.isReachableOnEthernetOrWiFi == true)
    {
     print("internet is available")
    }
    else
    {
    print("internet is not available")
    }

manager?.startListening()

manager?.listener = { status in

switch status {

   case .notReachable:
      print("network connection status - lost")
  case .reachable(NetworkReachabilityManager.ConnectionType.ethernetOrWiFi):
      print("network connection status - ethernet/WiFI")
  case .reachable(NetworkReachabilityManager.ConnectionType.wwan):
      print("network connection status - wwan")
  default:
      break
           }
    }     

}

}

Alamofire - NetworkReachabilityManager不能与.notReachable一起使用
