Como o título sugere, estou tentando criar um vcard para o meu usuário e enviá-lo ao servidor, mas parece que ele não funciona, alguma idéia? eu aprecio muito qualquer ajuda

Aqui está o meu código, juntamente com a conexão e a autenticação do fluxo, incluindo essa parte porque também pode haver algo errado com eles, como eu sou um noob trabalhando com a estrutura xmpp, o cliente iOS que eu uso é:https://github.com/robbiehanson/XMPPFramework

o código da classe .h é:

#import <UIKit/UIKit.h>
#import "XMPPStream.h"
#import "XMPP.h"
#import "XMPPReconnect.h"
#import "XMPPPresence.h"
#import "XMPPRoster.h"
#import "ForgotPasswordViewController.h"
#import "XMPPReconnect.h"
#import "XMPPRosterCoreDataStorage.h"
#import "ConractsViewController.h"
#import "KeychainItemWrapper.h"
#import "SignUpViewController.h"
#import "XMPPvCardTemp.h"
#import "XMPPvCardTempModule.h"
#import "XMPPvCardCoreDataStorage.h"

@interface SignInViewController : UIViewController <UITextFieldDelegate, XMPPRosterDelegate, XMPPStreamDelegate>

@property (strong, nonatomic) XMPPRosterCoreDataStorage *xmppRosterStorage;
@property (strong, nonatomic) XMPPRoster *xmppRoster;
@property (strong, nonatomic) XMPPReconnect *reconnect;
@property (strong, nonatomic) XMPPStream *xmppStream;

@end

implementação de classe .m

@implementation SignInViewController
@synthesize xmppRosterStorage, xmppRoster, reconnect, xmppStream;

- (void)viewDidLoad {

    //add SignIn button
    int signInButtonXPossition = [[UIScreen mainScreen] bounds].size.width * 0.1f;
    int signInButtonYPossition = [[UIScreen mainScreen] bounds].size.height * 0.55f;
    int signInButtonWidth = [[UIScreen mainScreen] bounds].size.width * 0.8f;
    int signInButtonHeight = [[UIScreen mainScreen] bounds].size.height * 0.07;
    UIButton *signInButton = [[UIButton alloc] initWithFrame:CGRectMake(signInButtonXPossition, signInButtonYPossition, signInButtonWidth, signInButtonHeight)];
    [signInButton addTarget:self
                     action:@selector(signInButtonFunction)
           forControlEvents:UIControlEventTouchUpInside];
    signInButton.backgroundColor = [UIColor colorWithRed:(167/255.f) green:(224/255.f) blue:(250/255.f) alpha:1];
    signInButton.layer.cornerRadius=[[UIScreen mainScreen] bounds].size.width * 0.05f;
    signInButton.layer.borderWidth=1.0;
    signInButton.layer.masksToBounds = YES;
    signInButton.layer.borderColor=[[UIColor whiteColor] CGColor];
    [self.view addSubview:signInButton];
    [signInButton setTitle:@"Sign In" forState:UIControlStateNormal];

}

- (void)signInButtonFunction{

    xmppStream = [[XMPPStream alloc] init];
    xmppStream.myJID = [XMPPJID jidWithString:@"test@administrator"];
    xmppStream.hostName = @"www.domainName.com";
    xmppStream.hostPort = 5222;
    [xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];

    reconnect = [[XMPPReconnect alloc] init];
    [reconnect activate:xmppStream];

    NSError *error = nil;
    if (![xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:&error]) {
        NSLog(@"error: %@", error);
    }
    NSLog(@"error: %@", error);

}

- (void)xmppStreamDidConnect:(XMPPStream *)sender {
    NSError *error = nil;

    if (![xmppStream authenticateWithPassword:@"test" error:&error]) {
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error"
                                                            message:[NSString stringWithFormat:@"Can't authenticate %@", [error localizedDescription]]
                                                           delegate:nil
                                                  cancelButtonTitle:@"Ok"
                                                  otherButtonTitles:nil];
        [alertView show];
    }
    XMPPPresence *mypresence = [XMPPPresence presenceWithType:@"available"];
    [xmppStream sendElement:mypresence];
}

- (void)xmppStreamWillConnect:(XMPPStream *)sender{
    NSLog(@"Did connect");
}

- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender{
    NSLog(@"e%d",[xmppStream isConnected]);//prints out 1
    NSLog(@"e%d",[xmppStream isAuthenticated]);//prints out 1

    if ([xmppStream isAuthenticated]) {
        NSLog(@"authenticated");

            XMPPvCardCoreDataStorage* xmppvCardStorage = [XMPPvCardCoreDataStorage sharedInstance];

            XMPPvCardTempModule *xmppvCardTempModule = [[XMPPvCardTempModule alloc] initWithvCardStorage:xmppvCardStorage dispatchQueue:dispatch_get_main_queue()];

            XMPPvCardTemp *xmppvCardTemp;
            NSXMLElement *vCardElement = [NSXMLElement elementWithName:@"vCard" xmlns:@"vcard-temp"];
            NSXMLElement *nicknameElement = [NSXMLElement elementWithName:@"nickname" stringValue:@"A0Test1"];
            [vCardElement addChild:nicknameElement];
            xmppvCardTemp = [XMPPvCardTemp vCardTempFromElement:vCardElement];
            [xmppvCardTempModule updateMyvCardTemp:xmppvCardTemp];
    }
}

Ele retorna 1 quando eu me conecto e quando me autentico, mas o cartão não é carregado, é correto o que faço, pelo menos parcialmente?
