如何在尤里卡中添加或更新另一部分的行？

Question

我的Eureka表格有StepperRow。

    var n = 1
    form +++ Section("")
        <<< TextRow(){ row in
            row.title = "Meal Plan Name"
            row.placeholder = "Name"
            row.cell.textField.autocapitalizationType = .none
        }

        <<< StepperRow().cellSetup({ (cell, row) in
            row.title = "Number of Meals Per Day"
            row.tag = "df"
            row.value = 1
            cell.valueLabel!.text = "\(Int(row.value!))"
        }).cellUpdate({ (cell, row) in
            if(row.value != nil)
            {
                cell.valueLabel!.text = "\(Int(row.value!))"
            }
        }).onChange({ (row) in
            if(row.value != nil)
            {
                row.cell.valueLabel!.text = "\(Int(row.value!))"
                if let mealSec = self.form.sectionBy(tag: "mealSection"){
                    if let mRow = self.form.rowBy(tag: "MealRow"){
                        mealSec.append(mRow)
                        mRow.reload()
                    }
                }
            }
            print("value changed")
        })

我尝试获取另一部分行的标签，并将行附加到“ StepperRow”的更改上，如上所示。但这没有用。我想更新另一部分。这是我要更新的多值部分。

  form +++
            MultivaluedSection(multivaluedOptions: [.Reorder, .Insert, .Delete],
                               header: "Meals"
                               ) {
                                $0.addButtonProvider = { section in
                                    return ButtonRow(){
                                        $0.title = "Add New Meal"
                                    }
                                }
                                $0.tag = "mealSection"
                                $0.multivaluedRowToInsertAt = { index in
                                    return ButtonRow("MealRow"){
                                        $0.title = "Meal \(n)"
                                        $0.cellStyle = .value1
                                        $0.tag = "MealRow"
                                        n+=1
                                        print(n)

                                        }.cellUpdate { cell, _ in
                                            cell.accessoryType = .disclosureIndicator
                                            cell.tintColor = .black
                                        }.onCellSelection { _, _ in
                                            // Instatiating and presenting the view controller

                                            let webView = MealVC()


                                            self.navigationController?.pushViewController(webView, animated: true)
                                    }

                                }
                                $0  <<< ButtonRow(){
                                    $0.title = "Meal 1"
                                    $0.cellStyle = .value1
                                    n+=1
                                    print(n)

                                    }.cellUpdate { cell, _ in
                                        cell.accessoryType = .disclosureIndicator
                                        cell.tintColor = .black
                                }

        }

在StepperRow更改时，应在多值部分中添加新餐行。
