XMPP connection issue on IOS using Swift

问题

I am trying to use the XMPP framework(https://github.com/robbiehanson/XMPPFramework) using swift. I am new to swift

    class ViewController: UIViewController {
    var password: NSString?
    var isOpen: Bool = false
    var xstream: XMPPStream?

    var loginServer: String = ""
    override func viewDidLoad() {
        super.viewDidLoad()
        println(connect())
        // 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.
    }

    func connect() ->Bool{


        var xstream = XMPPStream()
        var error: NSError?
        xstream.addDelegate(self, delegateQueue: dispatch_get_main_queue())

        xstream.myJID = XMPPJID.jidWithString("test@localhost")
        xstream.hostName="127.0.0.1"
        xstream.hostPort=5222
        var password = "testing"

        if !xstream.connectWithTimeout(XMPPStreamTimeoutNone, error: &error) {
          println(error)

        }
        println(xstream.isConnecting()) // This prints true
        return xstream.isConnected();// This prints false.
    }
}

The username and password and server details are correct because i use adium to connect to server and it works fine.

回答1:

Remember the connection takes some seconds to be established. Use the other delegate methods to track the state of the connection.

回答2:

Set your host name and port.

Call methods as described below.

• configureXMPP()
• configureXMPPElements()
• loginWithId("userId", password: "password")

After this, delegate methods will be called and authentication will be done.

After authentication, one must send presence.

self.xmppStream.send(XMPPPresence())

private var hostName: String = "your host name"
private var hostPort: UInt16 = 5222

private var xmppStream: XMPPStream!
private var xmppReconnect: XMPPReconnect!
private var xmppRoster: XMPPRoster!
private var xmppvCardStorage: XMPPvCardCoreDataStorage!

fileprivate func configureXMPP() {
    // Stream Configuration
    xmppStream = XMPPStream()
    xmppStream.addDelegate(self, delegateQueue: DispatchQueue.main)
    xmppStream.hostPort = hostPort
    xmppStream.hostName = hostName
    xmppStream.enableBackgroundingOnSocket = true

    xmppStream.startTLSPolicy = .required

    xmppAutoPing?.pingTimeout = 2

    // Reconnect
    self.xmppReconnect = XMPPReconnect()

    // Storage
    let xmppRosterStorage = XMPPRosterCoreDataStorage()

    self.xmppMessageArchivingModule.activate(self.xmppStream)
    self.xmppMessageArchivingModule.addDelegate(self, delegateQueue: DispatchQueue.main)

    //Activate xmpp modules
    self.xmppReconnect.activate(self.xmppStream)
    self.xmppRoster.activate(self.xmppStream)
    self.xmppvCardTempModule.activate(self.xmppStream)
    self.xmppvCardAvatarModule.activate(self.xmppStream)
    self.xmppCapabilities.activate(self.xmppStream)

    // Add ourself as a delegate to anything we may be interested in
    self.xmppRoster.addDelegate(self, delegateQueue: DispatchQueue.main)
}

func loginWithId(_ userId: String, password: String) {
    if self.xmppStream == nil {
        establishConnection()

        try self.xmppStream.authenticate(withPassword: password)
    }
    catch {
        print("not authenticate")
    }
}

// Delegate Methods
func xmppStream(_ sender: XMPPStream!, socketDidConnect socket: GCDAsyncSocket!) {
