不能在 DelegateProxyType (rxSwift) 中使用 proxyForObject 函数

Question

我尝试将 SRWebSocket 的委托迁移到可观察的。这是我的 RxSocketManagerDelegateProxy.swift:

class RxSocketManagerDelegateProxy: DelegateProxy, DelegateProxyType{

static func currentDelegateFor(object: AnyObject) -> AnyObject?{
    let socket: SRWebSocket = object as! SRWebSocket
    return socket.delegate
}

static func setCurrentDelegate(delegate: AnyObject?, toObject object: AnyObject) {
    let socket: SRWebSocket = object as! SRWebSocket
    socket.delegate = delegate as? SRWebSocketDelegate
}

}

extension SRWebSocket{
    public var rx_delegate: DelegateProxy{
    return DelegateProxyType.proxyForObject(self)
}

// ...

}

问题出在 proxyForObject 函数中。它不是像上面那样编译的。我收到警告 "Static member 'proxyForObject' cannot be used on instance of type 'DelegateProxyType.Protocol'"。

当我尝试像这样使用 proxyForObjectFunction 时（虽然它已被弃用）：

public var rx_delegate: DelegateProxy{
    return proxyForObject(RxSocketManagerDelegateProxy.self, self)
}

我收到消息 "assertion failed: : file /Users/Agentum/Documents/Xcode/Telemetry/Pods/RxCocoa/RxCocoa/Common/DelegateProxyType.swift"。

我应该如何使用 proxyForObject() 函数才能正确迁移委托？

您应该在 RxSocketManagerDelegateProxy 上呼叫 proxyForObject，而不是 DelegateProxyType。

extension SRWebSocket {
    public var rx_delegate: DelegateProxy {
        return RxSocketManagerDelegateProxy.proxyForObject(self)
        // instead of: `return DelegateProxyType.proxyForObject(self)`
    }
}
