Starscream delegates are not called

Question

The variable is not nil, I have a good connection, and the URL is correct, but the delegate methods are not called. I also use 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!") } 

Answer 1

Socket must be a property or variable of your class to make sure it adheres.

If you select it only in the function stack, it will fall out of scope and delegates will never receive a call

Here is the code I used in my project just in case

 import UIKit //import WebSocket import Starscream class ViewController: UIViewController,WebSocketDelegate,WebSocketPongDelegate { @IBOutlet weak var wsURL: UITextField! @IBOutlet weak var wsConsole: UITextView! @IBOutlet weak var wsMessage: UITextField! var socket:WebSocket! override func viewDidLoad() { super.viewDidLoad() // var webSocketObj:WebSocket = WebSocket() // webSocketObj.ipAddressText = "10.12.1.101" // webSocketObj.portText = "8888" // webSocketObj.dataToSendText = "hi" // webSocketObj.dataRecievedTextView = "" // webSocketObj.connectedLabel = "" // webSocketObj.connectToServer() wsURL.text="ws://10.12.1.101:8888/" wsMessage.text="Hi" self.navigationItem.leftBarButtonItem?.title="Connect" self.navigationItem.rightBarButtonItem?.enabled=false // Do any additional setup after loading the view, typically from a nib. } func websocketDidConnect(socket: WebSocket){ wsConsole.text = wsConsole.text .stringByAppendingString("\n websocket got connected") self.navigationItem.leftBarButtonItem?.title="Disconnect" self.navigationItem.rightBarButtonItem?.enabled=true } func websocketDidDisconnect(socket: WebSocket, error: NSError?){ wsConsole.text = wsConsole.text .stringByAppendingString("\n websocket got disconnected") self.navigationItem.leftBarButtonItem?.title="Connect" self.navigationItem.rightBarButtonItem?.enabled=false } func websocketDidReceiveMessage(socket: WebSocket, text: String){ wsConsole.text = wsConsole.text .stringByAppendingString("\n websocket got a message from server:").stringByAppendingString(text) } func websocketDidReceiveData(socket: WebSocket, data: NSData){ print("websocket received data",data) } @IBAction func writeText(sender: UIBarButtonItem) { wsConsole.text = wsConsole.text .stringByAppendingString("\n Client sent a message:").stringByAppendingString(wsMessage.text!) socket.writeString(wsMessage.text!) self.view .endEditing(true) } @IBAction func disconnect(sender: UIBarButtonItem) { self.view .endEditing(true) if socket == nil{ connect(sender) } else if socket.isConnected { socket.disconnect() } else { connect(sender) } } func connect(sender:UIBarButtonItem){ socket = WebSocket(url: NSURL(string:wsURL.text!)!) socket.delegate = self socket.connect() } func websocketDidReceivePong(socket: WebSocket){ wsConsole.text = wsConsole.text .stringByAppendingString("\n websocket received pong") } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } }
