使用 AlamofireObjectMapper 映射模型 - swift

【中文标题】使用 AlamofireObjectMapper 映射模型 - swift【英文标题】：using AlamofireObjectMapper for mapping model - swift 【发布时间】：2017-12-06 18:06:06 【问题描述】：我正在使用AlamofierObjectMapper 将来自服务器的 json 映射到我的模型。从服务器接收到的json是这样的：
[
"Title": "string",
"ImageUrl": "string",
"Url": "string",
"UrlType": "none"
]
我用于映射的类是：
class Banner: Mappable
var Title: String?
var ImageUrl: String?
var Url: String?
var UrlType: String?
required init?(map: Map)
// Mappable
func mapping(map: Map)
Title <- map["Title"]
ImageUrl <- map["ImageUrl"]
Url <- map["Url"]
UrlType <- map["UrlType"]
我的类不是数组，但我的 json 是数组。我怎样才能在没有这样的情况下获取数据：
"result" : [
"Title": "string",
"ImageUrl": "string",
"Url": "string",
"UrlType": "none"
]
编辑：
我的要求：
Alamofire.request(url, method: .get)
.responseObject (response: DataResponse<Banner>) in
【问题讨论】：
【参考方案1】：很简单，只需要使用方法responseArray：
Alamofire.request(url, method: .get).responseArray (response: DataResponse<[Banner]>) in
let bannersArray = response.result.value
if let bannersArray = bannersArray
for banner in bannersArray
// Do anything with it
【讨论】：
你的意思是我不使用我的请求，而是使用 Alamofire 请求并使用 mapArray 传递 json？ 对不起，一开始没有正确理解你，我已经更新了我的答案【参考方案2】：1) Model Class One--------------
-----------------------------------------
-----------------------------------------
import Foundation
import ObjectMapper

var per_page : Int?
var total : Int?

required init?(map: Map)
func mapping(map: Map)
page <- map["page"]

2) Model Class Two--------------
-----------------------------------------
-----------------------------------------
