ios - 红蜘蛛的socket.isConnected总是返回false

我正在使用Swift开发一个iOS应用程序，它通过套接字连接到Android设备。我已经实现了红蜘蛛并且能够连接到另一个设备。我的问题是，当我在websocketDidConnect委托方法上打印某些内容时，它不会打印。当我打印socket.isConnected时，它也会打印false。请帮帮我。谢谢。红蜘蛛的其他替代品也很受欢迎，谢谢！
这是我的代码：

    import Starscream
    class SettingsViewController: UIViewController, UITextFieldDelegate, WebSocketDelegate{

    override func viewDidLoad() {
            super.viewDidLoad()

        let socket = WebSocket(url: NSURL(string: "ws://\(ipAddressTextField.text!):4000/")!)
        socket.connect()

        print("socket.isConnected \(socket.isConnected)") //this one is false

        socket.onConnect = {
            print("Connected...") // does not print
        }

        socket.onDisconnect = { (error: NSError?) in
            print("websocket is disconnected: \(error?.localizedDescription)") // this one prints when I turn the wifi off
        }

        socket.onData = { (data: NSData) in
            print("got some data: \(data.length)")

        }

    }

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)")
}

}

最佳答案

您需要将其作为类属性，否则它将在离开viewDidLoad方法时被释放。
