SSID in Swift 2

Question

Im Versuch, diesen Code zu verwenden SSID zu erhalten

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 
    } 
} 

aber in einen Fehler in dieser Zeile immer let interfacesArray = interfaces.takeRetainedValue() as [String : AnyObject]

Der Fehler ist

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

Danke für Ihre Hilfe

Answer 1

In swift 2 müssen Sie nicht takeRetainedValue anrufen.

Den Code interfaces.takeRetainedValue() as [String : AnyObject] durch Array(arrayLiteral: interfaces) ersetzen.

Denken Sie auch daran, den Code interfacesArray[0] as String in String(interfacesArray[0]) zu ändern.

Voll 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 
} 

}

Answer 2

Dies kann Ihnen helfen (auf Swift 2 getestet):

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 
    } 
} 

Ich nahm und den Code von Ray Wenderlich Website angepasst (einmal war hier: Retrieve SSID in iOS9 aber jetzt wurde der spezifische Thread von der Seite entfernt)

Die folgende Funktion der WLAN-Name und der Mac zurückkehren Dieser Code funktioniert

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) 
} 

Adresse. Sie werden bemerken, einige Warnung in Ihrem Entwicklungsziel> = iOS9

Answer 4

Alle derzeit angebotenen Lösungen scheint ziemlich komplex, mit hässlichen unsicheren Güssen.

ich war in der Lage, eine solche prägnante Lösungen, die bis (ohne schwarze Magie überhaupt):

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 
} 

Answer 5

Das ist meine Lösung Swift 3iOS 10 und es funktioniert mit Xcode 8 gut ist

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 
    } 

} 

es zu benutzen:

let wifiName = network().getSSID() 

    guard wifiName != nil else { 

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

     return 
    } 


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

PS: Achtung es nicht funktioniert auf Simulator

Answer 6

In Swift 3 (arbeitet in Echtgerät und Simulator):

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 
    } 
} 

Verbrauch:

SSID.fetchSSIDInfo() 

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