swift - 带自定义对象的 PushRow 和 Eureka 表单

Question

我在使用 Eureka Form 中的自定义对象时遇到问题，我正在尝试从 Rest 服务加载对象，我正在使用 Alamofire 获取选项，我正在使用 row.options.append 来填充数据，当我选择单元格时，出现错误断言失败:重复标记构建

这是我的类，它符合 Equatable 协议(protocol)

class Building: Mappable, Equatable {
   var name_building: String?
   var id_building: Int?

   required init?(){
   }

   required init?(_ map: Map){   
   }

   func mapping(map: Map) {
      id_building <- map["id_building"]
      name_building <- map["name_building"]
   }
}

func == (lhs: Building, rhs: Building) -> Bool {
   return lhs.id_building == rhs.id_building
}

这是表格

class UserViewController: FormViewController {


    override func viewDidLoad() {
        super.viewDidLoad()

                    let user = User()

                    user.email = emailRow.value
                    user.name = nameRow.value

                    user.homeDepartureDate = homeDepartureTimeRow.value
                    user.jobEnterTime = buildingEnterTimeRow.value

                    let request = "requesttoCreateUser"

                    Alamofire.request(.POST, request, parameters: Mapper().toJSON(user), encoding: .JSON)
                        .validate()
                        .responseJSON { response in
                            switch response.result {
                            case .Success:
                                print("Validation Successful")
                            case .Failure(let error):
                                print(error)

        self.getBuilding();

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func getBuilding(){
        let buildingRow: PushRow<Building>! = self.form.rowByTag("kBuilding")

        let request = "requestToGetBuildings"

        Alamofire.request(.GET, request).responseArray { (response: Response<[Building], NSError>) in

            let buildingsArray = response.result.value

            if let buildingsArray = buildingsArray {
                for building in buildingsArray {
                    buildingRow.options.append(building)
                }
            }
        }
    }

}

它在 Eureka 类 BaseRow.swift 中崩溃了

    final func wasAddedToFormInSection(section: Section) {
        self.section = section
        if let t = tag {
            assert(section.form?.rowsByTag[t] == nil, "Duplicate tag \(t)")
            self.section?.form?.rowsByTag[t] = self
            self.section?.form?.tagToValues[t] = baseValue as? AnyObject ?? NSNull()
        }
        addToRowObservers()
        evaluateHidden()
        evaluateDisabled()
    }

如前所述here .

您需要做的就是使您的模型符合 CustomStringConvertible 协议(protocol)。

This is because the default implementation of SelectorViewController uses String(option) as the tag for your PushRow rows

所以你的类应该是这样的:

class Building: Mappable, Equatable,CustomStringConvertible {
   var name_building: String?
   var id_building: Int?
   var description: String {

        return name_building
    }
   required init?(){
   }

   required init?(_ map: Map){   
   }

   func mapping(map: Map) {
      id_building <- map["id_building"]
      name_building <- map["name_building"]
   }
}

func == (lhs: Building, rhs: Building) -> Bool {
   return lhs.id_building == rhs.id_building
}
