激活模塊：

_vCardStorage = [XMPPvCardCoreDataStorage sharedInstance];
_vCardTempModule = [[XMPPvCardTempModule alloc] initWithvCardStorage:_vCardStorage];
_vCardAvatarModule = [[XMPPvCardAvatarModule alloc] initWithvCardTempModule:_vCardTempModule];

[_vCardTempModule activate:_xmppStream];

更新名片信息：

vCard代理：XMPPvCardTempModuleDelegate

代理在登錄成功后 和 調(diào)用 [_vCardTempModule updateMyvCardTemp:vcard]; 方法后都會有一次回調(diào)。

/// 獲取到個人信息
- (void)xmppvCardTempModule:(XMPPvCardTempModule *)vCardTempModule 
didReceivevCardTemp:(XMPPvCardTemp *)vCardTemp forJID:(XMPPJID *)jid {}

發(fā)送IQ消息, 獲取名片內(nèi)容:

/// 發(fā)送IQ消息, 獲取名片內(nèi)容
- (void)getVCardMsgWithUserID:(NSString *)userID
{
    XMPPIQ *iq = [XMPPIQ iqWithType:@"get"];
    XMPPJID *JID = [XMPPJID jidWithUser:userID domain:@"domain" resource:@"resource"];
    [iq addAttributeWithName:@"to" stringValue:JID.bare];
    NSXMLElement *element = [NSXMLElement elementWithName:@"vCard" xmlns:@"vcard-temp"];
    [iq addChild:element];
    [_xmppStream sendElement:iq];
}

發(fā)送IQ消息后都會在 代理方法有回調(diào)

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

}
