我正在创建聊天应用程序，我正在使用 XMPP 代码，

这是显示崩溃的应用程序日志，如果有人知道解决方案，请帮助我

由于未捕获的异常而终止应用程序

'NSInvalidArgumentException',

原因：'-[XMPPvCardCoreDataStorage clearvCardTempForJID:xmppStream:]：无法识别的选择器发送到实例 0x29bbe0'

这是堆栈

我认为您正在调用以下方法，

- (void)clearvCardTempForJID:(XMPPJID *)jid  xmppStream:(XMPPStream *)stream

它应该用两个 arguments 即 JabberId 和 XmppStream object 调用。你可能设置错误。

[XMPPvCardCoreDataStorage clearvCardTempForJID:urNeededJid:xmppStream];
