POHow to filter the XMPP presence that is received in iOS?
text
Body
copied!<p>I am successfully able to receive presence i.e. status of users in my iOS XMPP client. But within that status is some extra info that I wish to extract. This info was added as a child to the presence while sending.</p> <p>Here is how I extended presence while sending:</p> <pre><code>- (void)updatePresence:(NSNotification *)notification { XMPPPresence *presence = [XMPPPresence presence]; NSString *string = [notification object]; // object contains some random string. NSXMLElement *status = [NSXMLElement elementWithName:@"status" stringValue:string]; [presence addChild:status]; NSLog(@"presence info :- %@",presence); [[self xmppStream] sendElement:presence]; } </code></pre> <p>Now when I am receiving presence I want to retrieve this extended portion of the presence. How can it be done?</p> <p>This is how I receive the presence:</p> <pre><code>- (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence { NSString *presenceType = [presence type]; // online / offline NSString *myUsername = [[sender myJID] user]; NSString *presenceFromUser = [[presence from] user]; NSString *presenceString=[presence fromStr]; NSString *string = @"@company.com"; if ([presenceString rangeOfString:string].location == NSNotFound) { if (![presenceFromUser isEqualToString:myUsername]) { if ([presenceType isEqualToString:@"available"]) { NSMutableDictionary *buddy=[[NSMutableDictionary alloc]init]; [buddy setObject:presenceFromUser forKey:@"name"]; [buddy setObject:[presence fromStr] forKey:@"jid"]; [_chatDelegate newBuddyOnline:buddy]; } else if ([presenceType isEqualToString:@"unavailable"]) { NSMutableDictionary *buddy=[[NSMutableDictionary alloc]init]; [buddy setObject:presenceFromUser forKey:@"name"]; [buddy setObject:[presence fromStr] forKey:@"jid"]; [_chatDelegate buddyWentOffline:buddy]; } } } } </code></pre>
