Question

donc je suis à la recherche à l'aide de cette api GitHub à qui vérifie l'accessibilité d'un hôte .: https://github.com/ashleymills/Reachability.swift/tree/feature/ios10

cependant ses os nus assez et j'obtenir quelques erreurs lorsque essayer d'écrire une fonction qui utilisera ce code. Je l'appeler de viewDidLoad

setupReachability(hostName: nil) 

var reachability:Reachability? 

var connected = false 

func setupReachability (hostName:String?) { 
    do { 
     let reachability = try hostName == nil ? Reachability() : Reachability(hostname: hostName!) 
     self.reachability = reachability 

     try! self.reachability?.startNotifier() 
    } catch ReachabilityError.FailedToCreateWithAddress(let address) { 
     print(address) 
     return 
    } catch {} 
    //now that the reacability function is created set a notification 
    NotificationCenter.default.addObserver(self, selector: "reachabilityChanged", name: ReachabilityChangedNotification, object: reachability) 

} 

func reachabilityChanged(notification: Notification) { 
    let reachability = notification.object as! Reachability 

    if reachability.isReachable { 
     if reachability.isReachableViaWiFi { 
      connected = true 
      print("Connected via WiFi") 
     } else { 
      connected = true 
      print("Connected via Cellular") 
     } 
    } else { 
     connected = false 
     print("Not Connected") 
    } 
} 

ceci est mon journal d'erreur:

Answer 1

Vous avez oublié deux points sur le sélecteur reachabilityChanged:. Vous en avez besoin pour indiquer qu'un argument doit être passé:

NotificationCenter.default.addObserver(self, selector: "reachabilityChanged:", name: ReachabilityChangedNotification, object: reachability)
