To retrive the roster directly in xmppframework try this:

<pre><code>- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq
{
 NSXMLElement *queryElement = [iq elementForName: @"query" xmlns: @"jabber:iq:roster"];

if (queryElement) {
 NSArray *itemElements = [queryElement elementsForName: @"item"];
 [ArrayUsers removeAllObjects];
 for (int i=0; i&lt;[itemElements count]; i++) {

 NSString *jid=[[[itemElements objectAtIndex:i] attributeForName:@"jid"] stringValue];
 [ArrayUsers addObject:jid];
 }



 }


 return NO;
}
</code></pre>

You will find didReceiveIQ in the AppDelegate method. In this way you will have at each login a complete list of your roster. Next if you want refresh for some reason this list you can try this:

<pre><code> NSXMLElement *queryElement = [NSXMLElement elementWithName: @"query" xmlns: @"jabber:iq:roster"];

NSXMLElement *iqStanza = [NSXMLElement elementWithName: @"iq"];
[iqStanza addAttributeWithName: @"type" stringValue: @"get"];
[iqStanza addChild: queryElement];

[xmppStream sendElement: iqStanza];
</code></pre>

I am half way through implementing my xmpp chatting module on iPhone using xmppframework library, having a little question here.

Based on some examples, I have done it this way:
- Once I am connected and authenticated, in the <code>xmppStreamDidAuthenticate</code> delegate, I will send my presence.
- And I will receive my roster presence in <code>didReceivePresence</code> delegate.

The problem is that I am now only receiving presence from all my online roster, but not the offline roster. How is it possible to request for a complete list of my roster?

I found there is a <code>fetchRoster</code> method in <code>XMPPRoster</code> class, but I have no idea how it should be called, and what should be the delegate for receiving the incoming roster information.

我使用xmppframework库在iPhone上实现我的xmpp聊天模块已经进行了一半，这里有一个小问题。基于一些例子，我是这样做的：-一旦我连接并验证了，在xmppStreamDidAuthenticate委托中，我将发送我的状态。-我将在didReceivePresence代表中收到我的花名册。问题是，我现在只收...
