Question

我希望此删除操作使用DelegateProxy与RxCcocoa和RxSwift反应。我收到此错误：

“＃selector”的参数引用实例方法未暴露给的'rangeSeekSlider（_：didChange：maxValue :)' Objective-C

我正在从此库转换的委托：https://github.com/WorldDownTown/RangeSeekSlider/blob/master/Sources/RangeSeekSliderDelegate.swift

import CoreGraphics

public protocol RangeSeekSliderDelegate: class {

/// Called when the RangeSeekSlider values are changed
///
/// - Parameters:
///   - slider: RangeSeekSlider
///   - minValue: minimum value
///   - maxValue: maximum value
func rangeSeekSlider(_ slider: RangeSeekSlider, didChange minValue: CGFloat, maxValue: CGFloat)

...
}

这是委托代理

import RxSwift
import RxCocoa
import RangeSeekSlider

final class RxRangeSeekSliderDelegateProxy:
DelegateProxy<RangeSeekSlider, RangeSeekSliderDelegate>,
RangeSeekSliderDelegate,
DelegateProxyType {

init(rangeSeekSlider: RangeSeekSlider) {
    super.init(parentObject: rangeSeekSlider, delegateProxy: RxRangeSeekSliderDelegateProxy.self)
}

static func registerKnownImplementations() {
    register { RxRangeSeekSliderDelegateProxy(rangeSeekSlider: $0) }
}

static func currentDelegate(for object: RangeSeekSlider) -> RangeSeekSliderDelegate? {
    return object.delegate
}

static func setCurrentDelegate(_ delegate: RangeSeekSliderDelegate?, to object: RangeSeekSlider) {
    object.delegate = delegate
}
}

滑块的反应性扩展，这是我得到错误的地方：

import RxSwift
import RxCocoa
import RangeSeekSlider


extension Reactive where Base: RangeSeekSlider {
var delegate: DelegateProxy<RangeSeekSlider, RangeSeekSliderDelegate> {
    return RxRangeSeekSliderDelegateProxy.proxy(for: base)
}

var didChange: Observable<(Bool, Bool)> {
    let source = delegate.methodInvoked(#selector(RangeSeekSliderDelegate.rangeSeekSlider(_:didChange:maxValue:)))
        .map{ (parameters) in
            return (parameters[0] as? Bool ?? false, parameters[1] as? Bool ?? false)
    }
    return source
}

}

本身协议需要暴露给Objective-C。

更改

public protocol RangeSeekSliderDelegate: class {

到

@objc public protocol RangeSeekSliderDelegate {

使用委托和RxCocoa显示'#selector'的参数引用未公开给Objective-C的实例
