How to get the message delivary status using XMPP framework

I am using the XMPP Framework for chatting between the users , Chatting is happening perfectly .Now I need to show the message is delivered perfectly to both devices like (What's app messenger). I am not getting any tutorial to follow. Below code represents while we send message to the other user.

//Sending the message to the other user
 NSXMLElement *body = [NSXMLElement elementWithName:@"body"];
 [body setStringValue:txtChat.text];

 NSXMLElement *message = [NSXMLElement elementWithName:@"message"];
 [message addAttributeWithName:@"type" stringValue:@"chat"];
 [message addAttributeWithName:@"to" stringValue:self.userjid];
 [message addChild:body];
 [[APPDELEGATE xmppStream] sendElement:message];

While reterving the message by using XMPP Framework i was getting the data by using below code

- (void)loadarchivemsg
{        
    XMPPMessageArchivingCoreDataStorage *storage = [XMPPMessageArchivingCoreDataStorage sharedInstance];
    NSManagedObjectContext *moc = [storage mainThreadManagedObjectContext];
    NSEntityDescription *entityDescription = [NSEntityDescription entityForName:@"XMPPMessageArchiving_Message_CoreDataObject"
                                                         inManagedObjectContext:moc];
    NSFetchRequest *request = [[NSFetchRequest alloc]init];

    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(bareJidStr like %@) && (streamBareJidStr like %@)", self.userjid,[[NSUserDefaults standardUserDefaults] stringForKey:@"kXMPPmyJID"]];
    request.predicate = predicate;
    NSLog(@"%@",[[NSUserDefaults standardUserDefaults] stringForKey:@"kXMPPmyJID"]);
    [request setEntity:entityDescription];
    NSError *error;
    NSArray *messages_arc = [moc executeFetchRequest:request error:&error];

    [self print:[[NSMutableArray alloc]initWithArray:messages_arc]];    
}

- (void)print:(NSMutableArray*)messages_arc{
    @autoreleasepool {
        for (XMPPMessageArchiving_Message_CoreDataObject *message in messages_arc) {

            NSXMLElement *element = [[NSXMLElement alloc] initWithXMLString:message.messageStr error:nil];
            XMPPMessage *message12=[[XMPPMessage alloc]init];
            message12 = [message message];
  }
}

In this why I was sending the message and retrieving the message,can you help me how to retrieve the delivery status of the message . Waiting for your valuable answers.

How to use a TurnSocket (XEP-0065: SOCKS5 Bytestreams) connection? XEP-0096: SI File Transfer? [socket writeData]?

I'm attempting file transfer via XMPP on iOS using the XMPPFramework and OpenFire. The base of my code is from the following tutorial. I have a successful TurnSocket (XEP-0065: SOCKS5 Bytestreams) connection, but I can't work how to use it to send data. There are 2 considerations I have, both of which I am stuck on: 1. Calling [socket writeData] and 2. Using 'XEP-0096: SI File Transfer'.

Possible solution 1 - Calling [socket writeData] In my App delegate I have a didSucceed method. I can call [socket writeData] like this ...

- (void)turnSocket:(TURNSocket *)sender didSucceed:(GCDAsyncSocket *)socket {

    NSLog(@"TURN Connection succeeded!");

    [socket writeData:myData withTimeout:60.0f tag:0]; 
    [turnSockets removeObject:sender];
}

Updated 14th June : Is this correct? If so, how does the other user read the data? I have tried implementing

- (void)socket:(GCDAsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag

but it never gets called. How do I ensure it gets called?

Possible solution 2 - XEP-0096: SI File Transfer Do I need to use XEP-0096: SI File Transfer? If so, how do I use my successful connection within the XEP-0096 XML I need to form? The XEP-0096 docs imply there is a 'hash' attribute, but I don't know where this comes from.

e.g.

<iq type='set' id='offer1' to='receiver@jabber.org/resource'>
  <si xmlns='http://jabber.org/protocol/si' 
      id='a0'
      mime-type='text/plain'

          size='1022'
          hash='552da749930852c69ae5d2141d3766b1'
          date='1969-07-21T02:56:15Z'>
      <desc>This is a test. If this were a real file...</desc>
    </file>

How to get prefrences in XEP-0136: Message Archiving?

My Message Archiving is fine , message is saving in database easily but for some reason i want to fetch the preference set for xep-0136 .

As stated in xep-0136 extension to get preference we need to send this IQ

<iq type="get" id="pref1">
    <pref xmlns="urn:xmpp:archive">
    </pref>
</iq>

But on sending this I am getting error in response that service is unavailable but i dont know how this can be possible ? because message archiving is working all fine. do i need to implement some other module.

error iq

<iq
    xmlns="jabber:client"
    from="ramu_gmail.com@##.##.##.##"
    to="ramu_gmail.com@##.##.##.##/42117879931439208568472324"

Guys please suggest.Thanks in advance.

Accepting chatroom invitation

I'm able to create a MUC using XMPPFramework and send user invitation requests to join that room by using the code below.

// Creating
AppDelegate *dele =(AppDelegate *) [[UIApplication sharedApplication]delegate];

xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:dele jid:[XMPPJID jidWithString:self.roomName] dispatchQueue:dispatch_get_main_queue()];
[xmppRoom addDelegate:dele delegateQueue:dispatch_get_main_queue()];
[xmppRoom activate:dele.xmppStream];
[xmppRoom joinRoomUsingNickname:self.myNick history:nil];

// Inviting
[xmppRoom inviteUser:[XMPPJID jidWithString:@"abc@host"] withMessage:@"Come Join me"];

How does a user "abc" know that he has received an invitation and how can he react to it either by accepting or declining?

I could not find any class in XMPPFramework which directly deal with chat room invitation. My research says that whenever a user receives an chatroom invitation, xmmppStream's delegate method is called:

- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message

In that message, I check whether the it contains NSXMLElement with name "invite", and if it contains then i send a callback to the user. Then i create chatroom with the same name as the name of the chatroom from which user received invitation and enter that newly created room. It works fine but quiet lengthy and not quiet efficient. I want to know if there is a class in XMPPFramework available here which could handle chat room invitation separately. For instance, detecting, accepting, and declining of room invitations.

My code for extracting room name:

- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message
{
    NSXMLElement * x = [message elementForName:@"x" xmlns:XMPPMUCUserNamespace];
    NSXMLElement * invite  = [x elementForName:@"invite"];
    NSXMLElement * decline = [x elementForName:@"decline"];
    NSXMLElement * directInvite = [message elementForName:@"x" xmlns:@"jabber:x:conference"];
    NSString *msg = [[message elementForName:@"body"]stringValue];
    NSString *from = [[[message attributeForName:@"from"]stringValue];
    if (invite || directInvite)
    {
        [self createAndEnterRoom:from Message:msg];
        return;
    }
    [self.delegate newMessageRecieved:msg];
}

XMPP framework - Location based app connected in background

I developed and app that is currently set as "Location based" so that it can run in the background indefenitely. It's not a trick i need it to do stuff when the user moves. After some search I learned that this app will only execute code on the event of a location change, no timer whatsoever will be able to execute any code after 10 mins.

My app, while in the background, stays connected to XMPP for 50mins or so, it then disconnects. I would like the app to never disconnect, I looked at the framework but I can't find the place where to fix this behaviour. Do you know if it's possible to stay connected "indefinetly"? if so what settings do I have to change in the xmppframework.

thanks

[EDIT] After 50mins the user is still connected to XMPP but it's disconnected of the XMPPRooms it was conected. On another run it was connected for 3 hours, the time the iPhone is connected doesnt seem to be consistent.

MUC How-to with XMPPFramework

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.

xmppstream delegate methods not getting called on my custom class

I started with xmppframework recently,but i am stuck with an issue.i am able to connect to my server on my local network but the xmppstreamdelegate methods are not getting called on my custom class,but works absolutely fine on appdelegate class .Can anyone pls help me on this.Is the delegate only supported on the appdelegate class ?

Header:

@interface XmppClass : NSObject<XMPPStreamDelegate>{
    XMPPStream *xmppStream;
    Login * loginDetail;

//        We are patiently waiting for a fix from Apple.

How to list only online users on facebook with xmpp framework

I have integrated xmpp in my app and able to list all the users in a table view, but I only want to display the online users and then want to implement the feature to send and recieve messages to my online friends...

Please suggest me some helpful code...

Here is my code, executed after facebook login.

    - (void)fbDidLogin
{
    NSLog(@"logged in.....................");
    [appDelegate.facebook requestWithGraphPath:@"me" andDelegate:self];

        xmppStreamFB = nil;  
    }
    xmppStreamFB = [[XMPPStreamFacebook alloc] init];
    xmpReconnect = [[XMPPReconnect alloc] initWithStream:xmppStreamFB];  

    if (xmppRosterStorage) {  
        [xmppRosterStorage release];  
        xmppRosterStorage = nil;  
    }
    xmppRosterStorage = [[XMPPRosterCoreDataStorage alloc] init];

    if (xmppRoster) {  
        [xmppRoster release];  
        xmppRoster = nil;  
    } 
    xmppRoster = [[XMPPRoster alloc] initWithStream:xmppStreamFB rosterStorage:xmppRosterStorage];

    [xmppStreamFB addDelegate:self];
    [xmppRoster addDelegate:self];
    [xmppRoster setAutoRoster:YES];

    xmppStreamFB.myJID = [XMPPJID jidWithString:[NSString stringWithFormat:@"%@@chat.facebook.com", uid]];

    // You may need to alter these settings depending on the server you're connecting to
    allowSelfSignedCertificates = NO;
    allowSSLHostNameMismatch = YES;

    // Uncomment me when the proper information has been entered above.
    NSError *error = nil;
    if (![xmppStreamFB connect:&error]) 
        NSLog(@"Error connecting: %@", error);

    if(!tableView)
    {
        tableView = [[UITableView alloc]initWithFrame:CGRectMake(0,0, 480, 320) style:UITableViewStylePlain];
    }
    [tableView setFrame:CGRectMake(0,0, 480, 320)];
    [tableView setTag:2];
    [tableView setDelegate:self];
    [tableView setDataSource:self];

    [tableView setAlpha:1.0];

    [self.view addSubview:tableView];

    [self.tableView reloadData];
    [self showTopBar];

}

I don't know the actual flow of the xmpp framework for showing users online and to implement chat feature...

i have the following delegate methods as well..

    - (void)xmppStreamDidSecure:(XMPPStreamFacebook *)sender
{

And the two methods for online and offline user presence, but don't know how to modify them for my task:

    - (void)goOnline
{
    NSXMLElement *presence = [NSXMLElement elementWithName:@"presence"];

    [[self xmppStream] sendElement:presence];
}

- (void)goOffline
{
    NSXMLElement *presence = [NSXMLElement elementWithName:@"presence"];
    [presence addAttributeWithName:@"type" stringValue:@"unavailable"];

    [[self xmppStream] sendElement:presence];
}

XMPP iOS Framework detect internet disconnection issue with OpenFire server

I have implemented chatting application using XMPP iOS Framework with OpenFire server.

Fortunately, application is running successfully but I am facing one issue of internet disconnection in application.

When user is getting logout or went in offline mode manually then it sends stanza to his/her rosters. So his/her rosters knows that user went in offline mode.

Now when internet will disconnect from user's device at that time application is not able to send presence stanza to server due to internet disconnection. So his/her rosters won't get information about that offline user and user will be shown in online mode only.

I thought something like OpenFire server might be able to check connected users and whenever any user gets disconnected it should send presence stanza with offline status to his rosters so they can know that this user is on offline mode.

Can anybody please help me if there is any way through which I can implement this feature.

It will be very helpful for me to solve this issue.

Thanks in advance.

Options for real-time web notifications and updates using Comet/XMPP vs WebSocket technologies on a Microsoft stack?

I am scoping out the architectural options for a project that will render live updates (like Facebook) of user activities - logins, photos, etc. Two main UI components of this are an auto-updating scrolling area where new notifications will be listed (photos, etc.), and a toolbar that will update with things like updated message counts, etc.

The contenders for this are Jabber/Comet/XMPP-based and WebSocket technologies.

Comet camp:

WebSockets camp:

Since this the existing infrastructure is a Microsoft stack, I would rather not introduce Java-based servers into the mix. Saying this, it leaves (a very attractive) WebSync (Comet), and SuperWebSocket (WebSockets). However the Pokein's DLL integration is fairly seamless into a .Net project as well.

Are there any more real production level WebSocket initiatives for .Net? Is it too early to adopt WebSockets on a Microsoft stack, and should I go in favor of something like Kazing?

I am still waiting for a report on our current user base's browser types and versions (checking for HTML5 compatibility). I am suspecting that this number will be low (older user base). If that is the case, the Comet option would be the winner.

What are some other things to consider?

Looking at some of the .Net initiatives like Sockets.IO and others, I'm thinking this may be too much in its infancy yet, to apply to a large scale production system.

Can I get some comments from anyone that has used any of the technologies and products listed above?

Thanks.

UPDATE

I am still hunting for some good WebSocket servers that are reliable on a production level. I added XSockets and SignalR to the Websockets camp after recently finding them. Hoewver, there are still two main contenders at this time. That could be just because of the fact that they have amazingly great marketing teams, good material available for developers - API's, and videos. A lot of other implementations seem to still be in new-born phases, where examples are given of connectivity with only a few clients. While this demonstrates the technology, these demos are not backed up with significant payload/load capacity data. Kaazing and LightStreamer do meet the requirements below.

XSockets has some nice examples, but again, missing some real production metrics.

It doesn't seem that SignalR has yet been tested in a true production environment. A scale-out solution is in development but doesn't appear stable yet. Looking forward to seeing how this project does in the future.

Primary requirements are:

  1. Ability to implement fallback technology (if HTML5/WebSockets are not available)
  2. High number of concurrent connections and number of messages per second
  3. Scalable - ability to add additional servers/nodes for larger traffic requirements
