In my chat application I want to get all online registered users. So everybody and not only people in my roster which is achieved with this code:
- (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence {
// a buddy went offline/online
NSString *presenceType = [presence type]; // online/offline
NSString *myUsername = [[sender myJID] user];
NSString *presenceFromUser = [[presence from] user];
if (![presenceFromUser isEqualToString:myUsername]) {
if ([presenceType isEqualToString:@"available"]) {
[_chatDelegate newBuddyOnline:[NSString stringWithFormat:@"%@@%@", presenceFromUser, @"chat.denederlandsewateren.nl"]];
} else if ([presenceType isEqualToString:@"unavailable"]) {
[_chatDelegate buddyWentOffline:[NSString stringWithFormat:@"%@@%@", presenceFromUser, @"chat.denederlandsewateren.nl"]];
}
}
}
With this code the users only sees other users who are 'friends' but I need all users registered on this particular domain. Is this possible with ejabberd?
- (void)getAllRegisteredUsers {
NSError *error = [[NSError alloc] init];
NSXMLElement *query = [[NSXMLElement alloc] initWithXMLString:@"<query xmlns='http://jabber.org/protocol/disco#items' node='all users'/>"
error:&error];
XMPPIQ *iq = [XMPPIQ iqWithType:@"get"
to:[XMPPJID jidWithString:@"DOMAIN"]
elementID:[xmppStream generateUUID] child:query];
[xmppStream sendElement:iq];
}
- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq
{
NSXMLElement *queryElement = [iq elementForName: @"query" xmlns: @"http://jabber.org/protocol/disco#items"];
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];
}
}
