Question

我的swift项目中有SignalR-ObjC的问题。我创建了与SR到我的集线器的连接，代码是：

import UIKit
import SignalR_ObjC


class ViewController: UIViewController, SRConnectionDelegate {


@IBOutlet weak var textFied_Username: UITextField!

@IBOutlet weak var textField_Password: UITextField!

@IBOutlet weak var btn_Login: UIButton!

var hubConnection = SRHubConnection(URLString: "http://myUrl.com");

var hubProxy = SRHubProxy();


var txt_Username : String = "username";
var txt_Password : String = "password";


override func viewDidLoad() {

    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}


@IBAction func btn_Login(sender: AnyObject) {




    txt_Username = textFied_Username.text!;


    txt_Password = textField_Password.text!;


    hubProxy = SRHubProxy(connection: hubConnection, hubName: "MyHub");

    let signInSelector = Selector("signInResponse:");

    hubProxy.on("signIn", perform: self, selector: signInSelector);


    hubConnection.delegate = self;


    hubConnection.start();

    self.SRConnectionDidOpen(hubConnection);





}

func SRConnectionDidOpen(connection: SRConnectionInterface!) {

    hubProxy.invoke("SignIn", withArgs: ["username","password"])


}


func signInResponse(response: String) {

    NSLog(response);
}

}

建立连接并且调用有效，但它没有收到消息，方法如下：

hubProxy.on("signIn", perform: self, selector: signInSelector);

不起作用和选择器：

signInSelector

永远不会打电话给

。任何人都可以帮我解决这个问题吗？谢谢你，抱歉我的英文不好，我希望问题很清楚。

Answer 1

Swift 4，Xcode 9

尝试在func声明中添加@objc选择器，这是我的工作示例：

func configureProxy() {
        let proxy: SRHubProxy? = createHubProxy(kHubName) as? SRHubProxy
        // we are using proxy-connection, to avoid parsing NSData ourselves.
        proxy?.on(kReceivedMessageSignalREventName, perform: self, selector: #selector(self.didReceiveMessage(_:)))
    }


@objc func didReceiveMessage(_ message: [AnyHashable: Any]?) {
    if (receiveMessageBlock != nil) {
        receiveMessageBlock!(message)
    }
}

Answer 2

hubConnection?.received = { [weak self] received in
        print("Error: \(received)")
    }
