XMPPFramework - How to register a new user account

问题:

I'm trying to use XMPPFramework to connect to an Openfire server and create a new user account. If I am already logged in as a different user, this code will create a new user account:

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];

Now what I want to do is make a connection to the server and create the user account WITHOUT first being connected as a different user. I've tried setting the hostname in xmppStream and making a connection (as below), but that fails to connect.

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];
}

Any ideas on how can I get this to connect and register the new user?

uses this code.

- (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"];
