swift3.0获取当前使用wifi SSID和SSID列表

概述func kGetUsedSSID()->String{ let interfaces = CNCopySupportedInterfaces() var ssid = "" if interfaces != nil { let interfacesArray = CFBridgingRetain(interfaces) as! Array<AnyObjec

func kGetUsedSSID()->String{    let interfaces = CNcopySupportedInterfaces()    var ssID = ""    if interfaces != nil {        let interfacesArray = CFBrIDgingRetain(interfaces) as! Array<AnyObject>        if interfacesArray.count > 0 {            //获取当前使用wifi//            let interfacename = interfacesArray[0] as! CFString//            let ussafeInterfaceData = CNcopyCurrentNetworkInfo(interfacename)//            if (ussafeInterfaceData != nil) {//                let interfaceData = ussafeInterfaceData as! Dictionary<String,Any>//                ssID = interfaceData["SSID"]! as! String//            }            //获取wifi列表            for name in interfacesArray {                let interfacename = name as! CFString                let ussafeInterfaceData = CNcopyCurrentNetworkInfo(interfacename)                if (ussafeInterfaceData != nil) {                    let interfaceData = ussafeInterfaceData as!
