XMPP获取不到电子名片XMPPvCardTemp

[Damon_Guo]

module激活了 代理添加了。
但是没有走回调方法。各位帮忙看看是什么问题 用户的vCard是有的，但是就是获取不到

  
   xmppvCardStorage=[XMPPvCardCoreDataStorage sharedInstance] ;
    xmppvCardTempModule = [[XMPPvCardTempModule alloc] initWithvCardStorage:xmppvCardStorage];
    
    xmppvCardAvatarModule = [[XMPPvCardAvatarModule alloc] initWithvCardTempModule:xmppvCardTempModule];
    
    
    [xmppReconnect         activate:xmppStream];
    [xmppRoster            activate:xmppStream];
    [xmppvCardTempModule   activate:xmppStream];
    [xmppvCardAvatarModule activate:xmppStream];
    
    [xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];
    [xmppvCardTempModule addDelegate:self delegateQueue:dispatch_get_main_queue()];
    
    
    [xmppStream setHostName:IP];
    [xmppStream setHostPort:5222];
