与XMPP服务器断开连接

Question

我正在使用XMPPFramework并使用自签名证书。我已使用

修改了设置

[settings setObject:[NSNumber numberWithBool:YES] forKey:(NSString *)kCFStreamSSLAllowsAnyRoot];

和

[settings setObject:[NSNumber numberWithBool:NO]
                         forKey:(NSString *)kCFStreamSSLValidatesCertificateChain];

我已经验证我可以使用Psi连接。有没有人见过这个错误？
