XMPPFramework - 如何注册新用户帐户

我正在尝试使用 XMPPFramework 连接到 Openfire 服务器并创建一个新的用户帐户。如果我已经以其他用户身份登录，此代码将创建一个新的用户帐户：

NSXMLElement *query = [NSXMLElement elementWithName:@"query" xmlns:@"jabber:iq:register"];
[query addChild:[NSXMLElement elementWithName:@"username" stringValue:userName]];
[query addChild:[NSXMLElement elementWithName:@"password" stringValue:pswd]];
NSXMLElement *iq = [NSXMLElement elementWithName:@"iq"];
[iq addAttributeWithName:@"type" stringValue:@"set"];
[iq addAttributeWithName:@"id" stringValue:@"reg2"];
[iq addChild:query];
[xmppStream sendElement:iq];

现在我想做的是连接到服务器并创建用户帐户，而无需首先作为其他用户进行连接。我尝试在 xmppStream 中设置主机名并建立连接（如下所示），但无法连接。

NSXMLElement *query = [NSXMLElement elementWithName:@"query" xmlns:@"jabber:iq:register"];
[query addChild:[NSXMLElement elementWithName:@"username" stringValue:userName]];
[query addChild:[NSXMLElement elementWithName:@"password" stringValue:pswd]];
NSXMLElement *iq = [NSXMLElement elementWithName:@"iq"];
[iq addAttributeWithName:@"type" stringValue:@"set"];
[iq addAttributeWithName:@"id" stringValue:@"reg2"];
[iq addChild:query];
[xmppStream sendElement:iq];

[xmppStream setHostName:@"192.168.1.5"];
[xmppStream setHostPort:5222];
NSError *error;
if (![xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:&error]) {
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error connecting"
                                                        message:@"See console for error details."
                                                       delegate:nil
                                              cancelButtonTitle:@"Ok"
                                              otherButtonTitles:nil];
    [alertView show];
}

关于如何连接并注册新用户有什么想法吗？

使用此代码。

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.


 ///  [[self appDelegate] connect];
    AppDelegate *delegate=[self appDelegate];
    [delegate connect];


    useSSL=NO;
    allowSelfSignedCertificates=NO;
    allowSSLHostNameMismatch=NO;
    customCertEvaluation=NO;
    isRegistering=NO;

    self.xmppStream= [[self appDelegate] xmppStream];

    BOOL *connect=[self.xmppStream isConnected];




    [self createAccount];
}

    - (void)updateAccountInfo
    {


        //NSString *domain = [[NSString alloc] initWithString:@"192.168.1.100"];

        //int port = 5222;
        NSString *usname =[[NSString alloc] initWithString:self.txtUsername.text];
        NSString *juser =[[NSString alloc] initWithString:[usname stringByAppendingString:@"your server ip"]];

        XMPPJID *jid = [XMPPJID jidWithString:juser];
        [self  xmppStream].myJID =jid;

        allowSelfSignedCertificates =  NSOnState;
        allowSSLHostNameMismatch    =  NSOnState;
        NSUserDefaults *dflts = [NSUserDefaults standardUserDefaults];

        //[dflts setObject:domain forKey:@"Account.Server"];

    //  [dflts setObject:(port ? [NSNumber numberWithInt:port] : nil)
            //    forKey:@"Account.Port"];

        [dflts setObject:juser
                  forKey:@"Account.JID"];
        [dflts setObject:@"ios"
                  forKey:@"Account.Resource"];

        [dflts setBool:useSSL                      forKey:@"Account.UseSSL"];
        [dflts setBool:allowSelfSignedCertificates forKey:@"Account.AllowSelfSignedCert"];
        [dflts setBool:allowSSLHostNameMismatch    forKey:@"Account.AllowSSLHostNameMismatch"];
        [dflts setBool:YES forKey:@"Account.RememberPassword"];

        [dflts setObject:self.txtPasswd.text forKey:@"Account.Password"];
        [dflts synchronize];



    }

        }

            success = [[self xmppStream] registerWithPassword:self.txtPasswd.text error:&error];
        }

        }
        else

        }
    }
    - (void)xmppStreamDidRegister:(XMPPStream *)sender{


        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Registration" message:@"Registration with XMPP Successful!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];

    }
