Swift：如何將JSON字符串與Alamofilre或SwiftyJSON轉換爲ObjectMapper？

Question

我目前使用 ObjectMapper斯威夫特用於映射JSON對象從API到模型對象

但我的RESTful API返回的API看起來像這樣

：

{ 
     success: true, 
     data: 
     [{ 
      "stats":{ 
      "numberOfYes":0, 
      "numberOfNo":2, 
      "progress":{ 
       "done":false, 
       "absolute":"2/100", 
       "percent":2 
      } 
      }, 
      "quickStats":null, 
      "uid":5, 
      "name":"Flora", 
      "imageArray":[ 
      "http://s3.com/impr_5329beac79400000", 
      "http://s3.com/impr_5329beac79400001" 
      ], 
      "metaData":{ 
      "description":"Floral Midi Dress", 
      "price":"40$" 
      } 
     }] 

} 

在數據節點陣列我不能看直到使用此代碼映射

let json = JSON(responseObject!) 

for tests in json["impressions"][0] { 
    let test = Mapper<myTests>().map(tests) 
    println(test?.impressionID) 
} 

我該如何解決？ 由於

ObjectModel映射結構

class Response: Mappable { 
    var success: Bool? 
    var data: [Data]? 

    required init?(_ map: Map) { 
     mapping(map) 
    } 

    func mapping(map: Map) { 
     success <- map["success"] 
     data <- map["data"] 
    } 
} 

class Data: Mappable { 
    var uid: Int? 
    var name: String? 
    // add other field which you want to map   

    required init?(_ map: Map) { 
     mapping(map) 
    } 

    func mapping(map: Map) { 
     uid <- map["uid"] 
     name <- map["name"] 
    } 
} 

映射與Alamofire響應

let response: Response = Mapper<Response>().map(responseObject)! 

for item in response.data! { 
    let dataModel: Data = item 
    println(dataModel.name) 
}

您可以使用下面的類結構映射的JSON以上：

class Response: Mappable { 
    var success: Bool? 
    var data: [Data]? 

    required init?(_ map: Map) { 
     mapping(map) 
    } 

    func mapping(map: Map) { 
     success <- map["success"] 
     data <- map["data"] 
    } 
} 

class Data: Mappable { 
    var uid: Int? 
    var name: String? 
    // add other field which you want to map   

    required init?(_ map: Map) { 
     mapping(map) 
    } 

    func mapping(map: Map) { 
     uid <- map["uid"] 
     name <- map["name"] 
    } 
} 

然後你可以如下圖吧：

let response = Mapper<Response>().map(responseObject) 
if let id = response?.data?[0].uid { 
    println(id) 
}
