I don't think there is any documentation, but the OS X sample app support MUC.

Hello -

For getting groups - I just attach a NSFetchedResultsController to the XMPPGroupCoreDataStorageObject entity and go from there. This will give you the list of groups as well as the array of users for each group. Something similar to:

       NSEntityDescription *groupsEntity = [NSEntityDescription
entityForName:@"XMPPGroupCoreDataStorageObject" inManagedObjectContext:moc];

        NSSortDescriptor *sortByName = [[NSSortDescriptor alloc]
initWithKey:@"name" ascending:YES];

        if (_groupsFetchRequest == nil) {

            _groupsFetchRequest = [[NSFetchRequest alloc] init];

        }

        [_groupsFetchRequest setEntity:groupsEntity];

        [_groupsFetchRequest setSortDescriptors:[NSArray
arrayWithObject:sortByName]];

        [_groupsFetchRequest setFetchBatchSize:10];

        // Set predicates if needed.

        // Setup the controller.

        // Set the cacheName to nil since we are going to be re-using the
controller

        // with different predicates when the list needs to change.

        _groupsFetchedResultsController = [[NSFetchedResultsController
alloc] initWithFetchRequest:_groupsFetchRequest

  managedObjectContext:moc

    sectionNameKeyPath:nil

              cacheName:nil];

        [_groupsFetchedResultsController setDelegate:self];

        // Fetch.

        NSError *error = nil;

        if (![_groupsFetchedResultsController performFetch:&error]) {

            DDLogError(@"Error performing fetch for groups: %@", error);

        }

HTH.

Hello All, I did looked in the OS X sample app but couldn't find the method or anything by which user can create the group. There are the method for create room which is as follows but it didn't get called any time.

• (void)xmppRoomDidCreate:(XMPPRoom *)sender

Can anyone please let me know how to create room/group. Thanks in advance

Hi !

I am newbie to Chat app development for iOS and have been working on this repo for a month.Well, I have found a class called XMPPRoom which implements XEP-0045 (MUC or Group chat protocol extension). I am still not able to get a clue on how to create a room based on that. I am using GTalk chat engine for testing purpose for now.Any help Or advice would be highly appreciated.

Thanks for reading me.

Read the header files and configure your server for the auto creation of such rooms but each server is different.

Look in the sample code of the mac client. Make sure you change all required parameter which match with your server and it should work.

Hey , did you know how to get list of group by sending XMPPIQ . I did what http://stackoverflow.com/questions/20792739/ios-xmpp-frame-work-xep-0048-bookmark-storage say , but I get 404 result . Help me , please.

[vaiism]

Bookmarks are not for getting groups, but for rooms that you are a part of, and that has to be supported by the server (XEP-0048). If you have a bookmark saved for you on the server, it will come back with you auth request generally, and let you know about auto-invite, etc.

Hello I am working on same for group chat . I tried above code but is giving me Roster list not group (muc room)list. Please suggest me a way so i can implement in proper manner(Group operations). Below Example Code:-

NSManagedObjectContext *moc = [appDelegate managedObjectContext_roster];
NSEntityDescription *entity = [NSEntityDescription entityForName:@"XMPPGroupCoreDataStorageObject"//XMPPUserCoreDataStorageObject
                                              inManagedObjectContext:moc];
 NSSortDescriptor *sd1 = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES];
//sectionNum
    NSArray *sortDescriptors = [NSArray arrayWithObjects:sd1, nil];
    NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
    [fetchRequest setEntity:entity];
    [fetchRequest setSortDescriptors:sortDescriptors];
    [fetchRequest setFetchBatchSize:10];
        NSError *error = nil;
        self.arrResult = (NSMutableArray*)[moc executeFetchRequest:fetchRequest error:&error];

    for (int i=0; i<[self.arrResult count]; i++) {
        XMPPGroupCoreDataStorageObject * user =[self.arrResult objectAtIndex:i];
        NSLog(@"user-%@",user.name);
        NSLog(@"user-%@",user.users);

    }

Is there any solution to get MUC list in iOS app using XMPP Framework? I am finding the group list but not giving me MUC details in list

[arthtilva]

You can use following code to get MUC members @meghaParmar `NSString server = [NSString stringWithFormat:@"conference.%@",XMPP_IP]; //or whatever the server address for muc is XMPPJID servrJID = [XMPPJID jidWithString:server];

//servrJID = [xmppRoom roomJID];

XMPPIQ *iq = [XMPPIQ iqWithType:@"get" to:servrJID];
[iq addAttributeWithName:@"from" stringValue:[APP_DELEGATE.xmppStream myJID].full];

NSXMLElement *query = [NSXMLElement elementWithName:@"query"];

XMPPMUC *xmppMuc = [[XMPPMUC alloc] init];
[xmppMuc addDelegate:self delegateQueue:dispatch_get_main_queue()];
[xmppMuc discoverRoomsForServiceNamed:server];

//[xmppMuc discoverRoomsForServiceNamed:@"conference.192.168.1.76"];

[query addAttributeWithName:@"xmlns" stringValue:@"http://jabber.org/protocol/disco#items"];

[iq addChild:query];
[APP_DELEGATE.xmppStream sendElement:iq];`

OR You can install this plugin in openfire and can use this API.

@arthtilva How do I display a profile picture of a chat room member

[arthtilva]

@LeftRightHand either you can use property or manage in your server by API
