Obtenir le SSID dans Swift 2

Im essayant d'utiliser ce code pour obtenir le SSID

import Foundation
import SystemConfiguration.CaptiveNetwork

public class SSID {
    class func getSSID() -> String{
        var currentSSID = ""
        let interfaces = CNCopySupportedInterfaces()
        if interfaces != nil {
            let interfacesArray = interfaces.takeRetainedValue() as [String : AnyObject]
            if interfacesArray.count > 0 {
                let interfaceName = interfacesArray[0] as String
                let unsafeInterfaceData = CNCopyCurrentNetworkInfo(interfaceName)
                if unsafeInterfaceData != nil {
                    let interfaceData = unsafeInterfaceData.takeRetainedValue() as Dictionary!
                    currentSSID = interfaceData[kCNNetworkInfoKeySSID] as! String
                    let ssiddata = NSString(data:interfaceData[kCNNetworkInfoKeySSIDData]! as! NSData, encoding:NSUTF8StringEncoding) as! String
                    //ssid data from hex
                    print(ssiddata)
                }
            }
        }
        return currentSSID
    }
}

Mais en avoir une erreur dans cette ligne
let interfacesArray = interfaces.takeRetainedValue() as [String : AnyObject]

L'erreur est

Value of type 'CFArray?' has no member 'takeRetainedValue'

Merci pour votre aide

Cela peut vous aider (testé sur Swift 2):

import Foundation
import SystemConfiguration.CaptiveNetwork

public class SSID {
    class func fetchSSIDInfo() -> String {
        var currentSSID = ""
        if let interfaces = CNCopySupportedInterfaces() {
            for i in 0..<CFArrayGetCount(interfaces) {
                let interfaceName: UnsafePointer<Void> = CFArrayGetValueAtIndex(interfaces, i)
                let rec = unsafeBitCast(interfaceName, AnyObject.self)
                let unsafeInterfaceData = CNCopyCurrentNetworkInfo("\(rec)")
                if unsafeInterfaceData != nil {
                    let interfaceData = unsafeInterfaceData! as Dictionary!
                    currentSSID = interfaceData["SSID"] as! String
                }
            }
        }
        return currentSSID
    }
}

Je l'ai pris et l'a adapté le code de Ray Wenderlich du site (une fois était ici:
Récupérer SSID dans iOS9 mais maintenant, le thread spécifique a été supprimé du site)

C'est ma solution Swift 3 iOS 10 et il fonctionne bien avec Xcode 8

import Foundation

import SystemConfiguration.CaptiveNetwork

class network : NSObject {

    func getSSID() -> String? {

        let interfaces = CNCopySupportedInterfaces()
        if interfaces == nil {
            return nil
        }

        let interfacesArray = interfaces as! [String]
        if interfacesArray.count <= 0 {
            return nil
        }

        let interfaceName = interfacesArray[0] as String
        let unsafeInterfaceData =     CNCopyCurrentNetworkInfo(interfaceName as CFString)
        if unsafeInterfaceData == nil {
            return nil
        }

        let interfaceData = unsafeInterfaceData as! Dictionary <String,AnyObject>

        return interfaceData["SSID"] as? String
    }

}

Pour l'utiliser:

let wifiName = network().getSSID()

    guard wifiName != nil else {

        ////TODO: Alert -----
        print("no wifi name")

        return
    }


    print("my network name is: \(wifiName!)")

PS: Attention il ne fonctionne sur simulateur

Toutes présentées à l'instant où les solutions semble plutôt complexe, avec laide dangereux jette.

J'ai été en mesure de concevoir un tel concis solution (pas de la magie noire):

import Foundation
import SystemConfiguration.CaptiveNetwork

func getSSID() -> String? {
    var ssid: String?
    if let interfaces = CNCopySupportedInterfaces() as NSArray? {
        for interface in interfaces {
            if let interfaceInfo = CNCopyCurrentNetworkInfo(interface as! CFString) as NSDictionary? {
                ssid = interfaceInfo[kCNNetworkInfoKeySSID as String] as? String
                break
            }
        }
    }
    return ssid
}

Dans Swift 3 (fonctionne en véritable appareil et le simulateur):

import SystemConfiguration.CaptiveNetwork

internal class SSID {
    class func fetchSSIDInfo() ->  String {
        var currentSSID = ""
        if let interfaces:CFArray = CNCopySupportedInterfaces() {
            for i in 0..<CFArrayGetCount(interfaces){
                let interfaceName: UnsafeRawPointer = CFArrayGetValueAtIndex(interfaces, i)
                let rec = unsafeBitCast(interfaceName, to: AnyObject.self)
                let unsafeInterfaceData = CNCopyCurrentNetworkInfo("\(rec)" as CFString)
                if unsafeInterfaceData != nil {

                    let interfaceData = unsafeInterfaceData! as Dictionary!
                    currentSSID = ((interfaceData as? [String : AnyObject])?["SSID"])! as! String

                }
            }
        }
        return currentSSID
    }
}

Utilisation:

SSID.fetchSSIDInfo()

//will return "" if no connected wifi or running in simulator

Dans swift 2, vous n'avez pas à appeler takeRetainedValue.

Remplacer le code interfaces.takeRetainedValue() as [String : AnyObject] avec Array(arrayLiteral: interfaces).

Souviens aussi de modifier le code interfacesArray[0] as String en String(interfacesArray[0]).

Complète du code ：

public class SSID {
class func getSSID() -> String{
    var currentSSID = ""
    let interfaces = CNCopySupportedInterfaces()
    if interfaces != nil {
        let interfacesArray = Array(arrayLiteral: interfaces)
        if interfacesArray.count > 0 {
            let interfaceName =  String(interfacesArray[0])
            let unsafeInterfaceData = CNCopyCurrentNetworkInfo(interfaceName)
            if unsafeInterfaceData != nil {
                let interfaceData = unsafeInterfaceData.takeRetainedValue() as Dictionary!
                currentSSID = interfaceData[kCNNetworkInfoKeySSID] as! String
                let ssiddata = NSString(data:interfaceData[kCNNetworkInfoKeySSIDData]! as! NSData, encoding:NSUTF8StringEncoding) as! String
                //ssid data from hex
                print(ssiddata)
            }
        }
    }
    return currentSSID
}

}

Swift 4 version

import SystemConfiguration.CaptiveNetwork


func getSSID() -> String? {
    guard let interface = (CNCopySupportedInterfaces() as? [String])?.first,
        let unsafeInterfaceData = CNCopyCurrentNetworkInfo(interface as CFString) as? [String: Any],
        let ssid = unsafeInterfaceData["SSID"] as? String else{
            return nil
    }
    return ssid
}

La fonction suivante retour le wifi nom et de l'adresse Mac

    func getNetworkInfo()->(success:Bool,ssid:String,mac:String){
      var currentSSID:String = ""
      var macAdrees:String = ""
      var succes:Bool = false
      let interfaces:CFArray! = CNCopySupportedInterfaces()
      for i in 0..<CFArrayGetCount(interfaces){
        let interfaceName: UnsafePointer<Void>
        =  CFArrayGetValueAtIndex(interfaces, i)
        let rec = unsafeBitCast(interfaceName, AnyObject.self)
        let unsafeInterfaceData = CNCopyCurrentNetworkInfo("\(rec)")
        if unsafeInterfaceData != nil {
            let interfaceData = unsafeInterfaceData! as Dictionary!
            currentSSID = interfaceData["SSID"] as! String
            macAdrees = interfaceData["BSSID"] as! String
            succes = true
        } else {
            currentSSID = ""
        }
    }

    return (succes, currentSSID, macAdrees)
}

Ce code fonctionne très bien. Vous noterez quelques avertissement dans le développement de votre cible >= iOS9

https://stackoverflow.com/users/3108877/rob's réponse -- version plus courte

func getSSID() -> String? {

Vous pouvez trouver une autre réponse avec mise à jour de normes Swift de @trucs réponse qui prend en charge les Swift 3 et Swift 4. De retour à vide "" sur des simulateurs.

import SystemConfiguration.CaptiveNetwork

internal class SSID {

    class func fetchSSIDInfo() -> String {
        var currentSSID = ""
        if let interfaces = CNCopySupportedInterfaces() {
            for i in 0..<CFArrayGetCount(interfaces){
                let interfaceName = CFArrayGetValueAtIndex(interfaces, i)

                guard let unsafeInterfaceData = CNCopyCurrentNetworkInfo("\(rec)" as CFString) else {

                currentSSID = SSID
            }
        }
        return currentSSID
    }
