Storing messages using XMPPFramework for ios?

user798719 picture user798719 · Dec 20, 2011 · Viewed 13.6k times · Source

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 :)
