Ios 套接字响应问题

我的应用程序中有五个选项卡。第二个选项卡在登录后显示，我在第三个选项卡的ViewDidDisplay中调用了socket connect，如下所示

SocketIOManager.sharedInstance.connectToServer(decoded, completionHandler: { (List) -> Void in
                dispatch_async(dispatch_get_main_queue(), { () -> Void in
                    print("response \(List)")
)}
)

在SocketIOManager中，输入以下代码

func connectToServer(data: AnyObject, completionHandler: (List: AnyObject) -> Void) {
    socket.on("connect") { (dataArray, socketAck) -> Void in
        self.socket.emit("api_request", data)
        print("Socket Connected")
    }
    socket.on("api_response") { ( dataArray, ack) -> Void in
        completionHandler(List: dataArray as AnyObject!)
        //print("acknowledgemt received from \(dataArray)")

    }

}

func applicationDidEnterBackground(application: UIApplication) {

        SocketIOManager.sharedInstance.closeConnection()
}

func applicationDidBecomeActive(application: UIApplication) {

        SocketIOManager.sharedInstance.establishConnection()
}

在下面的代码中

func connectToServer(data: AnyObject, completionHandler: (List: AnyObject) -> Void) {
    socket.on("connect") { (dataArray, socketAck) -> Void in
        self.socket.emit("api_request", data)
        print("Socket Connected")
    }
    socket.on("api_response") { ( dataArray, ack) -> Void in
        completionHandler(List: dataArray as AnyObject!)
        //print("acknowledgemt received from \(dataArray)")

    }

}

func applicationDidEnterBackground(application: UIApplication) {

        SocketIOManager.sharedInstance.closeConnection()
}

func applicationDidBecomeActive(application: UIApplication) {

        SocketIOManager.sharedInstance.establishConnection()
}

登录并按第三个选项卡后，我不会立即收到响应。只有在关闭并重新打开应用程序后才能获得响应。

您需要提供更多应用程序代码。另外，屏幕截图或更清晰的步骤会发生什么helpful@Alistra我尝试在socket.emit上放置断点，但在socket.on（“api_响应”）上没有响应
