無法與對象映射

Question

雙串下方解析我有有這兩個領域

var latitude: String? 
var longitude: String? 

我試圖解析模型的模型。一切都正確解析，但只有這兩個字段永遠不會被解析。

下面是完整的模型

import ObjectMapper 
class BarberLoginModel: Mappable { 
var id: Int? 
var barberShopId: Int = 0 
var firstName = "" 
var lastName = "" 
var mobileNo = "" 
var userName = "" 
var email = "" 
var imgPath = "" 
var shopName = "" 
var address = "" 
var street = "" 
var area = "" 
var emirates = "" 
var latitude: String? 
var longitude: String? 
var Services: [ServiceModel]? 
var Stylist: StylistArrayModel? 
var Availability: [AvailabilityModel]? 
var Facilities: [FacilitiesModel]? 

required init?(map: Map) { 

} 

func mapping(map: Map) { 
    id <- map["id"] 
    barberShopId <- map["barberShopId"] 
    firstName <- map["firstName"] 
    lastName <- map["lastName"] 
    mobileNo <- map["mobileNo"] 
    userName <- map["userName"] 
    email <- map["email"] 
    imgPath <- map["imgPath"] 
    shopName <- map["shopName"] 
    address <- map["address"] 
    street <- map["street"] 
    area <- map["area"] 
    emirates <- map["emirates"] 
    latitude <- map["latitude"] 
    longitude <- map["longitude"] 
    Services <- map["Services"] 
    Stylist <- map["Stylist"] 
    Availability <- map["Availability"] 
    Facilities <- map["Facilities"] 
} 
} 

注：當我改變數據類型爲Double？它的工作原理，但它增加了額外的數字，因爲雙。

這是相當困難的，而無需訪問實際數據調試。我在下面進行了一些小測試。如果您運行它，您將知道每個測試中的第二個XCTAssertEqual失敗，因爲原始JSON數據沒有圍繞值26.432引號。我的猜測是你的數據是一個數字而不是一個字符串，因此不會被正確解組。

import XCTest 
import ObjectMapper 

class Test : Mappable { 
    var latitude: String? 
    var longitude: String? 

    required init?(map: Map) { 

    } 

    func mapping(map: Map) { 
     latitude <- map["latitude"] 
     longitude <- map["longitude"] 
    } 
} 

class ObjectMapper_RndTests: XCTestCase { 

    override func setUp() { 
     super.setUp() 
    } 

    override func tearDown() { 
     super.tearDown() 
    } 

    func testExample() { 
     let json = "{\"longitude\": 26.432, \"latitude\":\"82.123\"}" 
     let test = Test(JSONString: json); 

     guard let t = test else { 
      return 
     } 

     XCTAssertEqual(t.latitude, "82.123") 
     XCTAssertEqual(t.longitude, "26.432") 
    } 

    func testExampleTwo() { 
     let json = [ "longitude": 26.432, "latitude": "82.123" ] as [String : Any] 
     let test = Test(JSON: json); 

     guard let t = test else { 
      return 
     } 

     XCTAssertEqual(t.latitude, "82.123") 
     XCTAssertEqual(t.longitude, "26.432") 
    } 
} 

解決方案如果您不能將數據源更改爲字符串，則使用轉換。 ObjectMapper網站https://github.com/Hearst-DD/ObjectMapper有更多信息。它看起來像這樣。

class Test : Mappable { 
    var latitude: String? 
    var longitude: String? 

    required init?(map: Map) { 

    } 

    func mapping(map: Map) { 

     let transform = TransformOf<String, Double>(fromJSON: { (value: Double?) -> String? in 

      if let v = value { 
       NSLog("from json value: " + String(v)) 
       return String(v) 
      } 
      NSLog("from json value: null") 
      return nil 
     }, toJSON: { (value: String?) -> Double? in 
      // transform value from Double? to String? 
      if let value = value { 
       return Double(value) 
      } 
      return nil 
     }) 

     latitude <- (map["latitude"], transform) 
     longitude <- (map["longitude"], transform) 
    } 
}
