I am developing a chat app in iOS using xmpp server. When i tried to connect to the server it returned 0 without any exception. All server credentials are true to the best of my knowledge. I tried many a times but couldn't found any fruitful help. Kindly give me a direction what should I do. Here is a code below.
xmppStream = [[XMPPStream alloc] init];
// [self setupStream];
NSXMLElement *presence = [NSXMLElement elementWithName:#"presence"];
[xmppStream sendElement:presence];
[xmppStream setMyJID:[XMPPJID jidWithString:#"app.com"]];
[xmppStream setHostName:#"appname.com"];
[xmppStream setHostPort:5222];
NSError *error2;
if ([xmppStream connect:&error2])
{
NSLog(#"Connected to XMPP.");
}
else
{
NSLog(#"Error connecting to XMPP: %#",[error2 localizedDescription]);
}
[self xmppStreamDidConnect:xmppStream];
//method is
- (void)setupStream {
NSLog(#"setupStream in delegate");
xmppStream = [[XMPPStream alloc] init];
[xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];
self.xmppStream.hostName = #"appname.com";
self.xmppStream.hostPort = (port);
[self connect];
}
Follow the connection class given in this link
Connection to server returns “0” only when you specify wrong HostName, HostPort or JID.
And one more thing you need not call xmppStreamDidConnect explicitly it will be called as delegate from XMPPFramework.
I'm working on an iOS app with XMPPFramework and Openfire Server. I work with a book to implement it, but there are some parts I don't understand because the book makes references to Google Talk and I can't figure out what to do in those methods:
The first one is about presence, here is the code that is implemented in the book:
-(void)goOnline
{
XMPPPresence *presence = [XMPPPresence presence];
NSString *domain = [self.xmppStream.myJID domain];
// Google set their presence priority to 24, so we do the same to be compatible.
if ([domain isEqualToString:#"gmail.com"] || [domain isEqualToString:#"gtalk.com"])
{
NSXMLElement *priority = [NSXMLElement elementWithName:#"priority" stringValue:#"24"];
[presence addChild:priority];
}
[[self xmppStream] sendElement:presence];
[self.rootViewController updateStatus:#"online"];
}
As I'm working on localhost with my own server name, I don't know exactly what to do with presence or if Openfire have a value for the presence priority.
For changing my logged status I used the following code:
XMPPPresence *presence = [XMPPPresence presenceWithType:#"away"];
[[self xmppStream] sendElement:presence];
But I am not getting the reference of [self xmppStream]. So I changed to the following code:
XMPPPresence *presence = [XMPPPresence presence];
NSXMLElement *status = [NSXMLElement elementWithName:#"status"];
[status setStringValue:#"away"];
[presence addChild:status];
NSError *error = nil;
xmppStream = [[XMPPStream alloc] init];
[xmppStream disconnect];
NSString *myJID = [NSString stringWithFormat:#"%#", appDelegate.jid];
XMPPJID *JID;
JID = [XMPPJID jidWithString:myJID];
NSLog(#"%#",JID);
[xmppStream setMyJID:JID];
xmppStream.hostName=#"talk.google.com";
[xmppStream connect:&error];
[xmppStream sendElement:presence];
Still not getting the changed status. Please share your ideas. Thanks in advance.
You can change your status immediately after you're logged in via goOnline method as it is called after xmppStreamDidAuthenticate.
- (void)goOnline
{
// Initialize XMPPPresence variable
XMPPPresence *presence = [XMPPPresence presence];
// Initialize XML element <show/> for specifying your status
NSXMLElement *show = [NSXMLElement elementWithName:#"show"];
// Initialize XML element <status/> for describing your status
NSXMLElement *status = [NSXMLElement elementWithName:#"status"];
// If you want your user status to be shown as "Available"
[show setStringValue:#"chat"];
[status setStringValue:#"Available"];
// If you want your user status to be shown as "Busy"
[show setStringValue:#"dnd"];
[status setStringValue:#"Busy"];
// If you want your user status to be shown as "Away"
[show setStringValue:#"away"];
[status setStringValue:#"Away"];
// If you want your user status to be shown as "Off-day"
[show setStringValue:#"xa"];
[status setStringValue:#"Off-day"];
// Add the XML elements to XMPPPresence
[presence addChild:show];
[presence addChild:status];
// Update new presence to server
[xmppStream sendElement:presence];
}

You have to wait until after you're connected to send stanzas, by listening for xmppStreamDidAuthenticate on the delegate.
Also, don't bother to set the to or from JID when broadcasting your presence.
I am developing an iOS XMPP chat app that utilizes Robbie Hanson's XMPPFramework.
The most important functionalities have been implemented - sending and receiving messages. Basically, I've built a basic functional chat app already, with a little eye candy of course.
Now, the problem I have is regarding MUC. The codes I saw from other websites show that there is a method initWithRoomName in XMPPRoom. However, this method is absent in the git repo I cloned. So, what is the alternative to this? Or, if there is none, how do I go about creating rooms using XMPPFramework?
Thanks.
Below is how I got my own problem solved. Note that this solution does not involve XMPPRoom at all. First, I created a method that, depending on the situation, either creates or enters a room. (Per XMPP documentation, the XML request for creating is the same is the same as the one you would send to enter a room; that is, if the room has does not exist yet when you enter it, the service will create it for you.)
Here we go. This is the method that creates/enters a room. What this method does is send a presence to the room which you intend to create/enter. If you are the first to enter a room and the room has not been created yet, you automatically become its owner and moderator.
- (void)createOrEnterRoom:(NSString *)roomName
{
//here we enter a room, or if the room does not yet exist, this method creates it
//per XMPP documentation: "If the room does not yet exist, the service SHOULD create the room"
//this method accepts an argument which is what you would baptize the room you wish created
NSXMLElement *presence = [NSXMLElement elementWithName:#"presence"];
NSString *room = [roomName stringByAppendingString:#"#conference.jabber.com/iMac"];
[presence addAttributeWithName:#"to" stringValue:room];
NSXMLElement *x = [NSXMLElement elementWithName:#"x" xmlns:#"http://jabber.org/protocol/muc"];
NSXMLElement *history = [NSXMLElement elementWithName:#"history"];
[history addAttributeWithName:#"maxstanzas" stringValue:#"50"];
[x addChild:history];
[presence addChild:x];
[[self xmppStream] sendElement:presence];
}
Next, in the AppDelegate where XMPPStream methods are declared we filter the XML response we receive in the didReceivePresence method by checking the status code sent by the server. If the status code is 201, bingo! The room creation went just fine. Status codes other than 201 mean different things, but let's focus on 201 for our purpose.
- (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence
{
NSXMLElement *x = [presence elementForName:#"x" xmlns:#"http://jabber.org/protocol/muc#user"];
for (NSXMLElement *status in [x elementsForName:#"status"])
{
switch ([status attributeIntValueForName:#"code"])
{
case 201: [self notifyRoomCreationOk:room];
}
}
}
Then, we tell the server that what we are creating a room of the type "instant," which means that we will send an IQ element telling it room defaults. notifyRoomCreationOk is a delegate method called in a different view when the room creation succeeds, after all I have to record the room in a text file to make it persistent so that the next time I open the app the room I created before will be visible. In my notifyRoomCreationOk method, I have sendDefaultRoomConfig which, basically, describes what is stated in the first sentence of this paragraph.
-(void)sendDefaultRoomConfig:(NSString *)room
{
NSXMLElement *x = [NSXMLElement elementWithName:#"x" xmlns:#"jabber:x:data"];
[x addAttributeWithName:#"type" stringValue:#"submit"];
NSXMLElement *query = [NSXMLElement elementWithName:#"query" xmlns:#"http://jabber.org/protocol/muc#owner"];
[query addChild:x];
XMPPIQ *iq = [XMPPIQ iq];
[iq addAttributeWithName:#"id" stringValue:[NSString stringWithFormat:#"inroom-cr%#", room]];
[iq addAttributeWithName:#"to" stringValue:room];
[iq addAttributeWithName:#"type" stringValue:#"set"];
[iq addChild:query];
[[self xmppStream ] sendElement:iq];
}
Make sure that you have XMPPStream enabled on the views that call the above methods, otherwise, these won't work. That's all there is to it. Have fun XMPP-ing!
XMPPRoom *room = [[XMPPRoom alloc] initWithRoomName:#"user101#conference.jabber.org/room" nickName:#"room"];
[room createOrJoinRoom];
[room sendInstantRoomConfig];
[room setInvitedUser:#"ABC#jabber.org"];
[room activate:[self xmppStream]];
[room inviteUser:jid1 withMessage:#"hello please join."];
[room sendMessage:#"HELLO"];
the user ABC#jabber.org should receive the invite message
Your post is old, however now I would do it like this:
- (void)createRoomWithJid:(XMPPJID*)roomJID
{
XMPPRoom *xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:self.xmppRoomHybridStorage
jid:roomJID
dispatchQueue:dispatch_get_main_queue()];
[xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];
[xmppRoom activate:self.xmppStream];
[xmppRoom joinRoomUsingNickname:self.xmppStream.myJID.user
history:nil
password:nil];
}
Create chat room by given below code using XMPPFRAMWORK.
let roomStorage: XMPPRoomMemoryStorage = XMPPRoomMemoryStorage()
/**
* Remember to add 'conference' in your JID like this:
* e.g. uniqueRoomJID#conference.yourserverdomain
*/
let roomJID: XMPPJID = XMPPJID.jidWithString("chatRoom_name#conference.myhostname")
let xmppRoom: XMPPRoom = XMPPRoom(roomStorage: roomStorage,
jid: roomJID,
dispatchQueue: dispatch_get_main_queue())
xmppRoom.activate(SKxmpp.manager().xmppStream)
xmppRoom.addDelegate(self, delegateQueue: dispatch_get_main_queue())
xmppRoom.joinRoomUsingNickname(SKxmpp.manager().xmppStream.myJID.user, history: nil, password: nil)
xmppRoom.fetchConfigurationForm()
I am trying to send message from simulator to device. On simulator there is one user while on device there is another user. But presence is not being received at any end.
I am using XMPPFramework for ios.
Here is the code I am using to send presence
NSXMLElement *presence = [NSXMLElement elementWithName:#"presence"];
[presence addAttributeWithName:#"to" stringValue:[NSString stringWithFormat:#"user1#server.com"]];
[presence addAttributeWithName:#"type" stringValue:#"available"];
[[self xmppStream] sendElement:presence];
But at the end where user1#server.com is logged in following method is NOT being invoked
- (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence
{
NSLog(#"---------- xmppStream:didReceivePresence: ----------");
}
What might be the issue?
The reason presence was not being sent is that code was incorrect. I used following code to send presence
XMPPPresence *presence = [XMPPPresence presence];
[[self xmppStream] sendElement:presence];
after that it showed user online on openfire server and message was correctly being sent to other users.
