XMPP connection issue on IOS using Swift - ios

Question

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.

Answer 1

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!
private var xmppvCardTempModule: XMPPvCardTempModule!
private var xmppvCardAvatarModule: XMPPvCardAvatarModule!
private var xmppCapabilities: XMPPCapabilities!
private var xmppCapabilitiesStorage: XMPPCapabilitiesCoreDataStorage!
private var xmppMessageArchivingStorage: XMPPMessageArchivingCoreDataStorage!
private var xmppMessageArchivingModule: XMPPMessageArchiving!
private var xmppAutoPing: XMPPAutoPing!
private var userId = ""
private var password = ""
fileprivate func configureXMPP() {
// Stream Configuration
xmppStream = XMPPStream()
xmppStream.addDelegate(self, delegateQueue: DispatchQueue.main)
xmppStream.hostPort = hostPort
xmppStream.hostName = hostName
xmppStream.enableBackgroundingOnSocket = true
xmppStream.keepAliveInterval = 0.5;
xmppStream.startTLSPolicy = .required
}
fileprivate func configureXMPPElements() {
//Autoping
xmppAutoPing = XMPPAutoPing(dispatchQueue: DispatchQueue.main)
xmppAutoPing?.activate(xmppStream)
xmppAutoPing?.addDelegate(self, delegateQueue: DispatchQueue.main)
xmppAutoPing?.pingInterval = 2
xmppAutoPing?.pingTimeout = 2
// Reconnect
self.xmppReconnect = XMPPReconnect()
// Storage
let xmppRosterStorage = XMPPRosterCoreDataStorage()
self.xmppRoster = XMPPRoster(rosterStorage: xmppRosterStorage, dispatchQueue: DispatchQueue.main)
self.xmppRoster.autoFetchRoster = true
self.xmppRoster.autoAcceptKnownPresenceSubscriptionRequests = true
self.xmppvCardStorage = XMPPvCardCoreDataStorage.sharedInstance()
self.xmppvCardTempModule = XMPPvCardTempModule(vCardStorage: xmppvCardStorage)
self.xmppvCardAvatarModule = XMPPvCardAvatarModule(vCardTempModule: xmppvCardTempModule)
self.xmppCapabilitiesStorage = XMPPCapabilitiesCoreDataStorage.sharedInstance()
self.xmppCapabilities = XMPPCapabilities(capabilitiesStorage: xmppCapabilitiesStorage)
self.xmppMessageArchivingStorage = XMPPMessageArchivingCoreDataStorage.sharedInstance()
self.xmppMessageArchivingModule = XMPPMessageArchiving(messageArchivingStorage: xmppMessageArchivingStorage)
self.xmppMessageArchivingModule.clientSideMessageArchivingOnly = false
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()
}
self.userId = userId
self.password = password
xmppStream.myJID = XMPPJID(string: userId)
do {
try xmppStream?.connect(withTimeout: XMPPStreamTimeoutNone)
} catch {
print("connection failed")
}
}
fileprivate func authentictae() {
do {
try self.xmppStream.authenticate(withPassword: password)
}
catch {
print("not authenticate")
}
}
// Delegate Methods
func xmppStream(_ sender: XMPPStream!, socketDidConnect socket: GCDAsyncSocket!) {
print("socketDidConnect:")
sender.enableBackgroundingOnSocket = true
}
func xmppStreamDidStartNegotiation(_ sender: XMPPStream!) {
print("xmppStreamDidStartNegotiation:")
}
func xmppStreamDidConnect(_ sender: XMPPStream!) {
authentictae()
print("Stream: Connected")
}
func xmppStreamDidAuthenticate(_ sender: XMPPStream!) {
print("Stream: Authenticated")
}

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