变量不是nil,我有一个很好的连接,url是正确的,但没有调用委托方法.我也正在实现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!")
}
解决方法
套接字应该是您的类的属性或变量,以确保它附近.
如果仅在函数堆栈上分配它,它将超出范围,并且永远不会调用委托
以下是我在项目中使用的代码,以防万一
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")
}
