Question

我很难将自定义行从以前版本的Eureka（大约3.0）迁移到Eureka 4.1。自定义行是自定义推送行，因此标签可以有多行，因此推送的视图控制器可以具有自定义节标题。可能有一种更好的方法来实现这一点，而不是拥有自定义行，这是一种可能的解决方案，但我不确定这是否可能。

所以有两个问题：自定义行和自定义选择器视图控制器。这是自定义行：

open class _StackedPushRow: SelectorRow<StackedPushCell, CustomSelectorViewController<String>> {

    public typealias StackedRow = PushRow<String>

    var dontClearWhenDisabled: Bool = false

    required public init(tag: String?) {
        super.init(tag: tag)
        cellProvider = CellProvider(nibName: "StackedPushCell")

        presentationMode = .show(controllerProvider: ControllerProvider.callback {
            return CustomSelectorViewController<Cell.Value> { _ in } },
         onDismiss: { vc in
            self.cell.update()
            _ = vc.navigationController?.popViewController(animated: true)
        })
    }
}

/// A generic inline row where the user can pick an option from a presented view controller
public final class StackedPushRow: _StackedPushRow, RowType {

    required public init(tag: String?) {
        super.init(tag: tag)
    }

}

这里是自定义选择器视图控制器：

public final class CustomSelectorViewController<T: Equatable>: SelectorViewController<T> {

    open override func viewDidLoad() {
        super.viewDidLoad()

        form.first?.header = HeaderFooterView.caliberStyleSectionHeader(title: row.title ?? "")
    }

    static func presentationMode<T: Equatable>() -> PresentationMode<SelectorViewController<T>> {
        return .show(controllerProvider: ControllerProvider.callback {
            return CustomSelectorViewController<T> { _ in }
        }, onDismiss: { vc in
            _ = vc.navigationController?.popViewController(animated: true)
        })
    }
}

以下是自定义行的错误：

我已经阅读了关于Github的问题部分并看到了其他人遇到的例子，但每当我尝试将这些例子付诸实践时，我遇到了其他问题，我只是继续在圈子里跑。我真的可以使用一些帮助。

感谢。

SelectorRow现在只采用通用的Cell类型，但没有视图控制器。 SelectorViewController由presentationMode定义。你应该声明你的行： open class _StackedPushRow: SelectorRow<StackedPushCell>

对于您的CustomSelectorViewController，您需要传递您将用作通用类型的rowType。该行类型必须符合OptionsProviderRow，例如ListCheckRow。

将自定义推送行迁移到Eureka 4.1
