ios – 红蜘蛛代表没有被召集

概述变量不是nil,我有一个很好的连接,url是正确的,但没有调用委托方法.我也正在实现WebSocketDelegate let socket = WebSocket(url: NSURL(string: "UrlHere:port/")!) socket.delegate = self; socket.connect() if 变量不是nil,我有一个很好的连接,url是正确的,但没有调用委托方法.我也正在实现WebSocketDelegate

let socket = WebSocket(url: NSURL(string: "UrlHere:port/")!)            socket.delegate = self;            socket.connect()            if socket.isConnected {                print("websocket is connected")            }    func websocketDIDConnect(ws: WebSocket) {        print("websocket is connected")    }    func websocketDIDdisconnect(ws: WebSocket,error: NSError?) {        if let e = error {            print("websocket is disconnected: \(e.localizedDescription)")        } else {            print("websocket disconnected")        }    }    func websocketDIDReceiveMessage(ws: WebSocket,text: String) {        print("Received text: \(text)")    }    func websocketDIDReceiveData(ws: WebSocket,data: NSData) {        print("Received data: \(data.length)")    }    func websocketDIDReceivePong(socket: WebSocket) {        print("Got pong!")    }

解决方法 套接字应该是您的类的属性或变量,以确保它附近.

如果仅在函数堆栈上分配它,它将超出范围,并且永远不会调用委托

以下是我在项目中使用的代码,以防万一
