当我连接到移动热点iOS Swift时如何检查网络连接

在我的应用程序中，我集成了

rechability.swift

。连接wifi时工作正常，但我想测试一个场景，比如连接到手机（没有互联网连接的热点）。当这个代码总是像connected一样执行时，因为状态是connected with wifi，但是我需要检查网络是否可用。还有其他的标准方式吗？请帮忙

using rechability same result

    let reachability: Reachability
    do {
        // reachability = try Reachability.NetworkReachable()

        reachability = try Reachability.reachabilityForInternetConnection()

        if (reachability.isReachableViaWiFi()) {
            _label.text = "wifi connected"
        }
        else if (reachability.isReachable()) {
            _label.text = "reachable"
        }

        else if (reachability.isReachableViaWWAN()) {
            _label.text = "connected via wan"

        }
        else {
            _label.text = "not connected "
        }
    } catch {
        print("Unable to create Reachability")
        return
    }

我使用的其他代码给出了相同的结果：

  func isConnectedToNetwork() -> Bool {

  var zeroAddress = sockaddr_in()
  zeroAddress.sin_len = UInt8(sizeofValue(zeroAddress))
  zeroAddress.sin_family = sa_family_t(AF_INET)
  let defaultRouteReachability = withUnsafePointer(&zeroAddress) {
    SCNetworkReachabilityCreateWithAddress(nil, UnsafePointer($0))
  }
  var flags = SCNetworkReachabilityFlags()
  if !SCNetworkReachabilityGetFlags(defaultRouteReachability!, &flags)    {
    return false
  }
  let isReachable = flags.contains(.Reachable)
  let needsConnection = flags.contains(.ConnectionRequired)
  //    let isReachable = (flags.rawValue & UInt32(kSCNetworkFlagsReachable)) != 0
  //    let needsConnection = (flags.rawValue &   UInt32(kSCNetworkFlagsConnectionRequired)) != 0
  return (isReachable && !needsConnection)
 }
