 required convenience init?(coder aDecoder: NSCoder) {
        let bssid = aDecoder.decodeObject(forKey: "bssid") as! String
        let ssid = aDecoder.decodeObject(forKey: "ssid") as! String
        let wifiType = aDecoder.decodeInteger(forKey: "wifiType")

        self.init(bssid: bssid, ssid: ssid, wiFiType: wifiType,lat:lat,lng:lng, femaleCounter: femaleCounter, maleCounter: maleCounter)
    }

init()方法

  init(bssid: String, ssid: String, wiFiType: Int,lat:Double,lng:Double, femaleCounter: Int, maleCounter: Int) {
        self.bssid = bssid
        self.ssid = ssid
        self.wifiType = wiFiType
        self.maleCounter = maleCounter
        self.femaleCounter = femaleCounter

    }

設(shè)置屬性

 var bssid: String?
    var ssid: String?
    var coordinate: CLLocationCoordinate2D?
    var femaleCounter = 0
    var maleCounter = 0
    var wifiType:Int = 0
    var lat:Double = 0.0
    var lng:Double = 0.0
