将自定义推送行迁移到Eureka 4.1

Question

我很难将自定义行从Eureka的早期版本(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，因此被推送的视图控制器可以有一个自定义节头。可能有更好的方法来实现这一点，而不是有一个自定义行，所以这是一个可能的解决方案，但我不确定这是否可能。

因此有两个问题:自定义行和自定义选择器视图控制器。以下是自定义行：

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)
    }

}

以下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：

我读过关于Github的问题部分，也看到过其他人遇到这种情况的例子，但是每次我尝试将这些例子付诸于实践时，我都会遇到其他的问题，我只是不停地循环运行。我真的需要帮助。

谢谢。

SelectorRow现在只采用一般单元格类型，而不采用视图控制器。SelectorViewController由presentationMode定义。您应该声明您的行如下：open class _StackedPushRow: SelectorRow<StackedPushCell>

对于CustomSelectorViewController，您需要传递要作为泛型类型使用的rowType。该行类型必须符合OptionsProviderRow，例如ListCheckRow。
