變量不是nil,我有一個很好得連接,url是正確得,但沒有調用委托方法.我也正在實現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!") }解決方法
套接字應該是您得類得屬性或變量,以確保它附近.
如果僅在函數堆棧上分配它,它將超出范圍,并且永遠不會調用委托
以下是我在項目中使用得代碼,以防萬一
import UIKit//import WebSocketimport Starscreamclass 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"http:// webSocketObj.portText = "8888"http:// webSocketObj.dataToSendText = "hi"http:// webSocketObj.dataRecievedTextView = ""http:// webSocketObj.connectedLabel = ""http:// 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. }} 這是link到故事板,以防萬一你想要
