如何使用Eureka创build自定义行内行？

我想像这里描述的那样使用Eureka实现一个自定义的inline cell 。 但是在我的具体情况下编译时遇到一些问题。 当我尝试运行以下错误时，Swift编译器崩溃。

 ... Call parameter type does not match function signature! ... 1. Running pass 'Module Verifier' on function'@_TWaC7TonyPro22ServiceCheckInlineRow26Eureka13InlineRowTypeS_' ... 

我的可折叠的行和单元格。

 public final class ServiceRow: Row<Service, ServiceCell>, RowType { ... } public class ServiceCell: Cell<Service>, CellType { ... } 

我的内联行

 public class ServiceCheckInlineRow: ImageCheckInlineRow<Service>, InlineRowType { public typealias InlineRow = ServiceRow required public init(tag: String?) { super.init(tag: tag) onExpandInlineRow { cell, row, _ in let color = cell.detailTextLabel?.textColor row.onCollapseInlineRow { cell, _, _ in cell.detailTextLabel?.textColor = color } cell.detailTextLabel?.textColor = cell.tintColor } } public override func customDidSelect() { super.customDidSelect() if !isDisabled { toggleInlineRow() } } public func setupInlineRow(inlineRow: InlineRow) { } } public class ImageCheckInlineRow<T where T: Equatable, T: ServiceType>: Row<T, ImageCheckCell<T>>, SelectableRowType, RowType { public var selectableValue: T? required public init(tag: String?) { super.init(tag: tag) displayValueFor = nil } } 

我认为问题的aliasType InlineRow是aliasType InlineRow但我不明白为什么。

你好我一直在处理你的问题，这是我的结果，这是怎样的样子

我将用eureka发布两个自定义行内示例

第一个示例是一个自定义行内滑块，其值为0..100

 public class ServiceInlineCell<T: Equatable> : Cell<T>, CellType { required public init(style: UITableViewCellStyle, reuseIdentifier: String?) { super.init(style: style, reuseIdentifier: reuseIdentifier) } public override func setup() { super.setup() accessoryType = .None editingAccessoryType = .None } public override func update() { super.update() selectionStyle = row.isDisabled ? .None : .Default } public override func didSelect() { super.didSelect() row.deselect() } } //MARK: PickerInlineRow public class _ServiceInlineRow : Row<Float, ServiceInlineCell<Float>>, NoValueDisplayTextConformance { public typealias InlineRow = SliderRow public var options = [Float]() public var noValueDisplayText: String? required public init(tag: String?) { super.init(tag: tag) } } /// A generic inline row where the user can pick an option from a picker view public final class ServiceInlineRow<T where T: Equatable> : _ServiceInlineRow, RowType, InlineRowType { required public init(tag: String?) { super.init(tag: tag) onExpandInlineRow { cell, row, _ in let color = cell.detailTextLabel?.textColor row.onCollapseInlineRow { cell, _, _ in cell.detailTextLabel?.textColor = color } cell.detailTextLabel?.textColor = cell.tintColor } } public override func customDidSelect() { super.customDidSelect() if !isDisabled { toggleInlineRow() } } public func setupInlineRow(inlineRow: InlineRow) { inlineRow.maximumValue = 100 inlineRow.steps = UInt(inlineRow.maximumValue / 10) inlineRow.displayValueFor = {(Float) in return "\(Float)" } } } 

然后在你的表单上，你需要把这个

  <<< ServiceInlineRow<Float>("PickerInlineRow") { (row : ServiceInlineRow<Float>) -> Void in row.title = row.tag row.value = 0 } 

这是另一个滑块但带有string值的例子

 public class CustomSliderInlineCell<T: Equatable> : Cell<T>, CellType { required public init(style: UITableViewCellStyle, reuseIdentifier: String?) { super.init(style: style, reuseIdentifier: reuseIdentifier) } public override func setup() { super.setup() accessoryType = .None editingAccessoryType = .None } public override func update() { super.update() selectionStyle = row.isDisabled ? .None : .Default } public override func didSelect() { super.didSelect() row.deselect() } } //MARK: PickerInlineRow public class _CustomSliderInlineRow<T where T: Equatable> : Row<T, CustomSliderInlineCell<T>>, NoValueDisplayTextConformance { public typealias InlineRow = CustomSliderRow<T> public var options = [T]() public var noValueDisplayText: String? required public init(tag: String?) { super.init(tag: tag) } } /// A generic inline row where the user can pick an option from a picker view public final class CustomSliderInlineRow<T where T: Equatable> : _CustomSliderInlineRow<T>, RowType, InlineRowType { required public init(tag: String?) { super.init(tag: tag) onExpandInlineRow { cell, row, _ in let color = cell.detailTextLabel?.textColor row.onCollapseInlineRow { cell, _, _ in cell.detailTextLabel?.textColor = color } cell.detailTextLabel?.textColor = cell.tintColor } } public override func customDidSelect() { super.customDidSelect() if !isDisabled { toggleInlineRow() } } public func setupInlineRow(inlineRow: InlineRow) { inlineRow.values = options inlineRow.displayValueFor = self.displayValueFor } } 

CustomSliderRow和Cell的定义

 public class CustomSliderCell<T: Equatable>: Cell<T>, CellType { public required init(style: UITableViewCellStyle, reuseIdentifier: String?) { super.init(style: .Value1, reuseIdentifier: reuseIdentifier) } public var titleLabel: UILabel! { textLabel?.translatesAutoresizingMaskIntoConstraints = false textLabel?.setContentHuggingPriority(500, forAxis: .Horizontal) return textLabel } public var valueLabel: UILabel! { detailTextLabel?.translatesAutoresizingMaskIntoConstraints = false detailTextLabel?.setContentHuggingPriority(500, forAxis: .Horizontal) return detailTextLabel } lazy public var slider: UISlider = { let result = UISlider() result.translatesAutoresizingMaskIntoConstraints = false result.setContentHuggingPriority(500, forAxis: .Horizontal) return result }() public var formatter: NSNumberFormatter? public override func setup() { super.setup() selectionStyle = .None slider.minimumValue = sliderRow.minimumValue slider.maximumValue = sliderRow.maximumValue print(sliderRow.values.count) slider.addTarget(self, action: #selector(CustomSliderCell.valueChanged), forControlEvents: .ValueChanged) if shouldShowTitle() { contentView.addSubview(titleLabel) contentView.addSubview(valueLabel!) } contentView.addSubview(slider) let views = ["titleLabel" : titleLabel, "valueLabel" : valueLabel, "slider" : slider] let metrics = ["hPadding" : 16.0, "vPadding" : 12.0, "spacing" : 12.0] if shouldShowTitle() { contentView.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("H:|-hPadding-[titleLabel]-[valueLabel]-hPadding-|", options: NSLayoutFormatOptions.AlignAllBaseline, metrics: metrics, views: views)) contentView.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("V:|-vPadding-[titleLabel]-spacing-[slider]-vPadding-|", options: NSLayoutFormatOptions.AlignAllLeft, metrics: metrics, views: views)) } else { contentView.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("V:|-vPadding-[slider]-vPadding-|", options: NSLayoutFormatOptions.AlignAllLeft, metrics: metrics, views: views)) } contentView.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("H:|-hPadding-[slider]-hPadding-|", options: NSLayoutFormatOptions.AlignAllBaseline, metrics: metrics, views: views)) } public override func update() { super.update() if !shouldShowTitle() { textLabel?.text = nil detailTextLabel?.text = nil } //slider.value = row.value ?? 0.0 slider.value = 0.0 } func valueChanged() { let roundedValue: Float //let steps = Float(sliderRow.steps) let steps = Float(sliderRow.values.count-1) if steps > 0 { let stepValue = round((slider.value - slider.minimumValue) / (slider.maximumValue - slider.minimumValue) * steps) let stepAmount = (slider.maximumValue - slider.minimumValue) / steps roundedValue = stepValue * stepAmount + self.slider.minimumValue } else { roundedValue = slider.value } //row.value = roundedValue row.value = sliderRow.values[Int(roundedValue)] if shouldShowTitle() { valueLabel.text = "\(row.value!)" } } private func shouldShowTitle() -> Bool { return row.title?.isEmpty == false } private var sliderRow: CustomSliderRow<T> { return row as! CustomSliderRow } } /// A row that displays a UISlider. If there is a title set then the title and value will appear above the UISlider. public final class CustomSliderRow<T: Equatable>: Row<T, CustomSliderCell<T>>, RowType { public var minimumValue: Float = 0.0 public var maximumValue: Float = 10.0 public var steps: UInt = 20 public var values : [T] = [T](){ willSet(newValues) { maximumValue = Float(newValues.count-1) steps = UInt(newValues.count) cell.setup() } } required public init(tag: String?) { super.init(tag: tag) } } 

而在你的forms，你需要把

 <<< CustomSliderInlineRow<String>("CustomSliderRow"){ (row : CustomSliderInlineRow<String>) -> Void in row.title = row.tag row.options = ["Value1","Value2","Value3"] row.value = "Value1" }
