Question

我无法在Eureka表单中使用自定义对象，我尝试从Rest服务加载对象，我使用Alamofire获取选项，我正在使用行。 options.append来填充数据，当我选择单元格时，我得到一个错误断言失败：重复标记构建

这是我的类符合Equatable 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

                    user.homeDepartureDate = homeDepartureTimeRow.value

                    Alamofire.request(.POST, request, parameters: Mapper().toJSON(user), encoding: .JSON)
                        .validate()

        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()
    }

如上所述here。

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

这是因为SelectorViewController的默认实现使用String（选项）作为PushRow行的标记

所以你的课应该是这样的：

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
}

使用Eureka Forms自定义对象的PushRow
