fetch all registered users in xmpp ios in openfire

Question

I am facing issue in fetching all registered users in XMPP ios project. I am using openfire.

Below are the code i am using but it always gives me zero in the arraylist.:-

- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq
{
    NSXMLElement *queryElement = [iq elementForName: @"query" xmlns: @"jabber:iq:roster"];
    if (queryElement)
    {
        NSArray *itemElements = [queryElement elementsForName: @"item"];
        NSMutableArray *mArray = [[NSMutableArray alloc] init];
        for (int i=0; i<[itemElements count]; i++)
        {
            NSString *jid2=[[[itemElements objectAtIndex:i] attributeForName:@"jid"] stringValue];
            [mArray addObject:jid2];
        }
        NSLog(@"didReceiveIQ Array======%@",mArray);
        [[NSNotificationCenter defaultCenter] postNotificationName:@"FriendRequestSend" object:nil];
    }
    return NO;
}

Though i can see 3 users in the browser. Note: I had seen the post iOS XMPP framework get all registered users but it does not work.

Please help me and advice me there is mistake in the code

Answer 1

If you are able to make changes in Openfire, You can develop a servlet (http service) in admin app which will simply return all users from ofUser table.
Or a custom packet, if you want to use XMPP.

I was working on getting all registered users from openfire into my app. After trying a lot i got a solution for getting all the registered users... here's the code :

- (void)getAllRegisteredUsers {

    NSError *error = [[NSError alloc] init];
    NSXMLElement *query = [[NSXMLElement alloc] initWithXMLString:@"<query xmlns='jabber:iq:roster'/>" error:&error];
    XMPPIQ *iq = [DDXMLElement elementWithName:@"iq"];
    [iq addAttributeWithName:@"type" stringValue:@"get"];
    [iq addAttributeWithName:@"none" stringValue:@"ANY_ID_NAME"];
    [iq addAttributeWithName:@"both" stringValue:@"ANY_ID_NAME"];
    [iq addChild:query];
    [xmppStream sendElement:iq];
}

- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq{

    NSXMLElement *queryElement = [iq elementForName: @"query" xmlns: @"jabber:iq:roster"];

    if (queryElement) {
        NSArray *itemElements = [queryElement elementsForName: @"item"];
        NSMutableArray *mArray = [[NSMutableArray alloc] init];
        for (int i=0; i<[itemElements count]; i++) {

            NSString *jid=[[[itemElements objectAtIndex:i] attributeForName:@"jid"] stringValue];
            [mArray addObject:jid];
        }
        NSLog(@"%@",mArray);
    }
    return YES;
}

This worked for me, hope it will work for others as well... :)
