Question

我正在使用xmpframework创建一个iphone应用程序，一切正常，但我想用以下代码更新我的个人资料图片。我得到了一些不正确的递归vCard-temp请求到服务器。但是图片得到了更新，并通知了我名单中的所有朋友。

//I clicked on the button
-(void)updatevCardButtonClicked{
   XMPPvCardTemp *vCardTemp = [[[self appDelegate] xmppvCardTempModule] myvCardTemp];
   NSLog(@"my vCardTemp: %@", vCardTemp);
   NSData *tempImage = [self getDataFromImage:[self resizeImage:userImage]];
   [vCardTemp setPhoto: tempImage];
   [[[self appDelegate] xmppvCardTempModule]updateMyvCardTemp:vCardTemp];
}

下面的输出和说明

my vCardTemp: *nil description*

//repeat the above in the rest of the output with more and more "vcard-temp:x:update"

我到目前为止所发现的，下面引起了这个问题，但我无法弄清楚我可以解决它的问题。

//i found that these two "SEND" cause the problem, the app just keep sending these two 
SEND: <iq type="get" to="myJabberAccount@127.0.0.1"><vCard xmlns="vcard-temp"/></iq>
SEND: <presence>

 //this presence keep growing as you can see the repeated parts

（iOS）递归vCard-temp请求到jabber服务器？
