Storing messages using XMPPFramework for ios?

Question

I'm not sure how to use the XMPPFramework's core data to store incoming messages. Does anyone have any tutorials on how to do this? I see User objects, which in turn can have many "resources". Is each message received supposed to be a new resource that I create and persist?

I do not know what part is my responsibility and what part the framework provides regarding message history. I can intercept every incoming message. Then am I supposed to create and store each message inside a Messages table using core data? I'd have a Message Entity. And each XMPPUser would have an array of Message objects. But then wouldn't I be rolling my own solution, which would be working against the framework?

Thanks!

I know this is an old thread but as I am currently working with XMPP on iOS I must say that there is a built in support for archiving messages in XMPP.

I downloaded the XMPP framework for iOS and in it there is folder marked XEP-0136. Import the folders in XCode and activate client side archiving by using the following lines of code in the class you instantiate XMPP client:

xmppMessageArchivingStorage = [XMPPMessageArchivingCoreDataStorage sharedInstance];
xmppMessageArchivingModule = [[XMPPMessageArchiving alloc] initWithMessageArchivingStorage:xmppMessageArchivingStorage];

the following one line of code saves you from sending archive specific stanzas to the xmpp server which will most probably respond with service-not-implemented

[xmppMessageArchivingModule setClientSideMessageArchivingOnly:YES];

[xmppMessageArchivingModule activate:xmppStream];
[xmppMessageArchivingModule  addDelegate:self delegateQueue:dispatch_get_main_queue()];

And you are set. From that moment on, messages (outgoing and incoming) will be stored in a table created by the framework.

If you need more info please comment and i will get back to you.

I did like this :

-(void)testMessageArchiving{
            XMPPMessageArchivingCoreDataStorage *storage = [XMPPMessageArchivingCoreDataStorage sharedInstance];
            NSManagedObjectContext *moc = [storage mainThreadManagedObjectContext];
            NSEntityDescription *entityDescription = [NSEntityDescription entityForName:@"XMPPMessageArchiving_Message_CoreDataObject"
                                                                 inManagedObjectContext:moc];
            NSFetchRequest *request = [[NSFetchRequest alloc]init];
            [request setEntity:entityDescription];
            NSError *error;
            NSArray *messages = [moc executeFetchRequest:request error:&error];

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

-(void)print:(NSMutableArray*)messages{
         @autoreleasepool {
            for (XMPPMessageArchiving_Message_CoreDataObject *message in messages) {
                NSLog(@"messageStr param is %@",message.messageStr);
                NSXMLElement *element = [[NSXMLElement alloc] initWithXMLString:message.messageStr error:nil];
                NSLog(@"to param is %@",[element attributeStringValueForName:@"to"]);
                NSLog(@"NSCore object id param is %@",message.objectID);
                NSLog(@"bareJid param is %@",message.bareJid);
                NSLog(@"bareJidStr param is %@",message.bareJidStr);
                NSLog(@"body param is %@",message.body);
                NSLog(@"timestamp param is %@",message.timestamp);
                NSLog(@"outgoing param is %d",[message.outgoing intValue]);
            }
        }
}

Hope it helps :)

The responses that indicate XMPP Framework doesn't save the history are incorrect.

To integrate results in a table view use:

XMPPMessageArchivingCoreDataStorage *storage = [XMPPMessageArchivingCoreDataStorage sharedInstance];
NSManagedObjectContext *moc = [storage mainThreadManagedObjectContext];
NSEntityDescription *entityDescription = [NSEntityDescription entityForName:@"XMPPMessageArchiving_Contact_CoreDataObject"
                                                     inManagedObjectContext:moc];
NSFetchRequest *request = [[NSFetchRequest alloc]init];
[request setEntity:entityDescription];

_contactsController = [[NSFetchedResultsController alloc] initWithFetchRequest:request managedObjectContext:moc sectionNameKeyPath:nil cacheName:@"MessagesContactListCache"];

NSError *error;
BOOL rval = [_contactsController performFetch:&error];
