ios - Swift JSON 项目数组

Question

大家好，我有一个问题。我在 swift 中使用 JSON 来获取有关用户的信息，因此响应是:

{
  "user_details": {
    "name":"samsun",
    "email_id":"charchit2@ymail.com",
    "mobile":"9503322593",
    "phone":"NA",
    "phone_os":"NA",
    "devicetoken":"",
    "city":"Mumbai",
    "state":"Maharashtra",
    "DOB":"0000-00-00",
    "gender":"Female",
    "address":"Shanti apts, A105",
    "pinCode":"400068",
    "isRegistered":"verified",
    "imei":"" 
  },
  "vehicles": {
    "1": {
      "vechicle_no":"MH03AW0001",
      "model_no":"Alto 800",
      "variant":"LXI",
      "color":"White",
      "date_of_purchase":"10/10/2014",
      "insurance_company_name":"Bajaj",
      "insurance_expiry_date":"10/10/2015",
      "created_at":"2015-06-02 23:31:30",
      "fuelType":"CNG",
      "vinNumber":"HSJHFJ10" 
    },
    "2": {
      "vechicle_no":"MH48S8403",
      "model_no":"Swift",
      "variant":"VXI",
      "color":"AZURA GREY",
      "date_of_purchase":"17/10/2007",
      "insurance_company_name":"NEW INDIA",
      "insurance_expiry_date":"17/10/2007",
      "created_at":"2015-06-27 22:22:57",
      "fuelType":"Petrol",
      "vinNumber":"ABCD0316"
    }
  },
  "status":"1",
  "verified":"true"
}

好的，现在我需要保存车号(vehicle_no)，但是因为有不同的用户，我需要保存第一个车号、第二个车号、第三个车号等。例如，这个用户有两个车号，我可以看到它，因为“2”后面有第二个车号。那么我怎样才能获得这两个车牌号呢？如果用户有的话，我还需要能够读取第三、第四个车辆号码。抱歉，如果我没有解释清楚，但提前谢谢您。

这是我现在的 json 代码。

 func MyVehicleInfo() {

    let Mobile = save.stringForKey("USERNAME")!

    let post:NSString = "mobile=9503322593"

    NSLog("PostData: %@",post);

    let url:NSURL = NSURL(string: "http://saimobileapp.com/services/sai_authenticate.php")!

    let postData:NSData = post.dataUsingEncoding(NSASCIIStringEncoding)!

    let postLength:NSString = String( postData.length )

    let request:NSMutableURLRequest = NSMutableURLRequest(URL: url)
    request.HTTPMethod = "POST"
    request.HTTPBody = postData
    request.setValue(postLength as String, forHTTPHeaderField: "Content-Length")
    request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
    request.setValue("application/json", forHTTPHeaderField: "Accept")


    var reponseError: NSError?
    var response: NSURLResponse?

    var urlData: NSData? = NSURLConnection.sendSynchronousRequest(request, returningResponse:&response, error:&reponseError)
    println(urlData)
    if ( urlData != nil ) {
        let res = response as! NSHTTPURLResponse!;

        NSLog("Response code: %ld", res.statusCode);
        if (res.statusCode >= 200 && res.statusCode < 300)
        {
            let responseData:NSString  = NSString(data:urlData!, encoding:NSUTF8StringEncoding)!

            NSLog("Response ==> %@", responseData);

            var error: NSError?

            let jsonData:NSDictionary = NSJSONSerialization.JSONObjectWithData(urlData!, options:NSJSONReadingOptions.MutableContainers , error: &error) as! NSDictionary




            let vehiclenodb = ((jsonData ["vehicles"] as! NSDictionary)["1"]! as! NSDictionary)["vechicle_no"]! as! String
            let modelnodb = ((jsonData ["vehicles"] as! NSDictionary)["1"]! as! NSDictionary)["model_no"]! as! String
            let variantdb = ((jsonData ["vehicles"] as! NSDictionary)["1"]! as! NSDictionary)["variant"]! as! String
            let colordb = ((jsonData ["vehicles"] as! NSDictionary)["1"]! as! NSDictionary)["color"]! as! String
            let datepurchasedb = ((jsonData ["vehicles"] as! NSDictionary)["1"]! as! NSDictionary)["date_of_purchase"]! as! String
            let insurancecompanynamedb = ((jsonData ["vehicles"] as! NSDictionary)["1"]! as! NSDictionary)["insurance_company_name"]! as! String
            let insuranceexpirydatedb = ((jsonData ["vehicles"] as! NSDictionary)["1"]! as! NSDictionary)["insurance_expiry_date"]! as! String
            let fueltypedb = ((jsonData ["vehicles"] as! NSDictionary)["1"]! as! NSDictionary)["fuelType"]! as! String
            //var emaildb = ((jsonData as NSDictionary)["user_details"] as! NSDictionary) ["email_id"] as! String



            var vehicleno:Void = save.setObject(vehiclenodb, forKey: "VehicleNumberSave")
            var modelno:Void = save.setObject(modelnodb, forKey: "ModelNumberSave")
            var variant:Void = save.setObject(variantdb, forKey: "VariantSave")
            var color:Void = save.setObject(colordb, forKey: "ColorSave")
            var datepurchase:Void = save.setObject(datepurchasedb, forKey: "DateofPurchaseSave")
            var insurancecompanyname:Void = save.setObject(insurancecompanynamedb, forKey: "InsuranceCompanySave")
            var insuranceexpirydate:Void = save.setObject(insuranceexpirydatedb, forKey: "InsuranceExpirySave")
            var fueltype:Void = save.setObject(fueltypedb, forKey: "FuelTypeSave")

            save.synchronize()





        }
    }



}

这是你必须处理的一些丑陋的 JSON。您可以像这样提取车辆。

if let vehicles = jsonData["vehicles"] as? NSDictionary {
   let vehiclesKeys = vehicles.allKeys
   for key in vehiclesKeys {
     println(vehicles[key])
   }
}
