XMPPFramework - Presence not changing

Question

I'm trying to set the users presence to away (or anything at the moment). I'm using the following code but it doesn't seem to do anything.

XMPPPresence *presence = [XMPPPresence presence];
NSXMLElement *show = [NSXMLElement elementWithName:@"show" stringValue:@"away"];

NSXMLElement *status = [NSXMLElement elementWithName:@"status" stringValue:@"away"];
[presence addChild:show];
[presence addChild:status];
[[self xmppStream] sendElement:presence];

I've used iChat to make sure all the presence subscriptions on my Ejabberd server are correct and working. This is driving me crazy, am I missing something?

Answer 1

I figured it out, turns out the presence wasn't being sent out by the app as I'd missed this out:

- (MMApplication *)appDelegate {
    return (MMApplication *)[[UIApplication sharedApplication] delegate];
}
- (XMPPStream *)xmppStream {
    return [[self appDelegate] xmppStream];
}

Works perfectly now
