iOS: XMPP: Message Archiving for Group Chat Message

Asked 8/8, 2014 at 8:45 Answered 4/6, 2015 at 5:46

ios xmpp message xmppframework archiving

All one-one chat is send with Message Type as Chat. Thus the Message Archiving technique (shown below) worked fine for me to save/retrieve chat history.

// Setup message archiving
xmppMessageArchivingStorage = [XMPPMessageArchivingCoreDataStorage sharedInstance];
xmppMessageArchiving = [[XMPPMessageArchiving alloc] initWithMessageArchivingStorage:xmppMessageArchivingStorage];
[xmppMessageArchiving setClientSideMessageArchivingOnly:YES];

// Activate xmpp modules
[xmppMessageArchiving   activate:xmppStream];
// Add delegate
[xmppMessageArchiving  addDelegate:self delegateQueue:dispatch_get_main_queue()];

However for Group Chat, the message type sent is "groupchat" This will not be archived by the XMPPMessageArchivingCoreDataStorage

Can someone please guide me as to how I can achieve the Message Archiving for Group Chat Message.

Y you need archive room messages.If u joined a new room , u can get all messages already there in that room – Incise 8/8, 2014 at 8:48

But I would want all messages saved even after I have joined it. So that I can show all messages right from the archive. – Sacramental 8/8, 2014 at 8:51

This is the Series of Stanza that you will need to send to get Archived Messages. For more detail you can checkout http://xmpp.org/extensions/xep-0136.html

Hello @Mrug, I used github.com/robbiehanson/XMPPFramework. I don't know how to store these retrieved messages please help me with this. – Imphal 22/11, 2017 at 13:52

Just follow the above series of Stanza you will get the response in XML, which you will need to parse and store either in SQLite or Coredata. – Underexpose 23/11, 2017 at 11:36

I used XMPPFramework and this framework automatically stores the messages and I want to store these archived messages with coredata database which is created by XMPPFramework so the problem is I am not able to store these messages @Underexpose – Imphal 23/11, 2017 at 11:46

You can easily get archive messages from xmpp core database. Use Below code.

XMPPMessageArchivingCoreDataStorage *_xmppMsgStorage = [XMPPMessageArchivingCoreDataStorage sharedInstance];
NSManagedObjectContext *moc = [_xmppMsgStorage mainThreadManagedObjectContext];
NSEntityDescription *entityDescription = [NSEntityDescription entityForName:@"XMPPMessageArchiving_Message_CoreDataObject"
                                                     inManagedObjectContext:moc];
NSFetchRequest *request = [[NSFetchRequest alloc]init];
[request setEntity:entityDescription];
//[request setFetchLimit:20];

NSError *error;
NSString *predicateFrmt = @"bareJidStr == %@";

NSPredicate *predicate = [NSPredicate predicateWithFormat:predicateFrmt, [NSString stringWithFormat:@"%@%@",GroupName,GROUP_CHAT_DOMAIN]];
request.predicate = predicate;
NSArray *messages = [moc executeFetchRequest:request error:&error];
