如何在swift

Question

这是我的json值

"end_location" = {
        "location_name" = "";
        pLatitude = "<null>";
        pLongitude = "<null>";
    };
    "start_location" =         {
        "location_name" = "<null>";
        pLatitude = "<null>";
        pLongitude = "<null>";
    }; 

我想将此json的数据设置为

下面的类

    class busLocationAndDetails {
    class bus_location {

       var pLatitude:String!
       var pLongitude:String!

    }
    class busDeatils {

       var busStatus:String!
       var busName:String!
    }
  }

我将直接从班级访问数据 busLocationAndDetails.bus_location.pLatitude 这必须从json返回数据

谢谢

由于您要使用这些类来存储数据，因此最好使用struct而不是类。

struct BusLocationAndDetails {

    var busLocation : BusLocation
    var busDetails : BusDetails

    init(dictionary : [ String: AnyObject]){
        let latitude = dictionary["pLatitude"] as! String
        let longitude = dictionary["pLongitude"] as! String

        busLocation = BusLocation(lat: latitude, long: longitude)
        busDetails = BusDetails(status: "", name: "")

    }

    struct BusLocation {
        var pLatitude:String!
        var pLongitude:String!

        init( lat: String, long :String ){
            pLatitude = lat
            pLongitude = long
        }

    }
    struct BusDetails {
        var busStatus:String!
        var busName:String!

        init( status: String, name :String ){
            busStatus = status
            busName = name

        }

    }
}

然后你可以保存这些值

var busLocationAndDetails = BusLocationAndDetails(dictionary: yourJson)
//yourJson value should be the values of the key end_location

然后你可以获得像

这样的值

var latitude = busDetails.busLocation.pLatitude
