I am developing one ios app, in that I need to enter company-code and accesscode to login. After login for the first time with the access code, We cannot prefer to ask for accesscode again when we open the application. I mean I need to save the preferences.

And my code is here

- (IBAction)loginClicked:(id)sender {



@try {



    if([[txtsecurecode text] isEqualToString:@""]  || [[OrganizationCode text] isEqualToString:@""] ) {

        [self alertStatus:@"Please enter Access code" :@"Login Failed!":0];

    } else {

        NSString *post =[[NSString alloc] initWithFormat:@"txtsecurecode=%@ @&password=%@",[txtsecurecode text],[OrganizationCode text]];

        NSLog(@"PostData: %@",post);

        NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];

        NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://mycompany.com/AccountService/security/ValidateAccess?accesscode=%@&companycode=%@&type=1", txtsecurecode.text, OrganizationCode.text]];





        [[ NSUserDefaults standardUserDefaults] setValue:OrganizationCode forKey:@"OrganizationCode"];

        [[ NSUserDefaults standardUserDefaults] setValue:txtsecurecode forKey:@"txtsecurecode"];

        [[NSUserDefaults standardUserDefaults] synchronize];



        txtsecurecode = [[NSUserDefaults standardUserDefaults] objectForKey:@"txtsecurecode"];

        OrganizationCode = [[NSUserDefaults standardUserDefaults] objectForKey:@"OrganizationCode"];



       // NSString *num = [[NSUserDefaults standardUserDefaults] stringForKey:@"txtsecurecode"];



        NSString *responseData = [[NSString alloc]initWithData:[NSData dataWithContentsOfURL:url] encoding:NSUTF8StringEncoding];



        if([responseData isEqualToString:@""]){

            [self alertStatus:@"Please enter valid Access Code" :@"Login Failed !" :0];

        }

        else

        {



        responseData = [responseData stringByReplacingOccurrencesOfString:@" "" " withString:@""];

        responseData = [responseData stringByReplacingOccurrencesOfString:@"\" withString:@""];



        NSString* encodedString = [responseData stringByReplacingPercentEscapesUsingEncoding:

                                   NSUTF8StringEncoding];



        NSLog(@"Response ==> %@" ,encodedString);



         UIWebView *webView;

         webView = [[UIWebView alloc] initWithFrame:CGRectMake(0,0, 320, 470)];

         webView.backgroundColor = [UIColor clearColor];

         webView.opaque = NO;

         [webView setDelegate:self];



        NSString* urlTwo = [[encodedString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]

                            stringByReplacingOccurrencesOfString:@"%22" withString:@""];



        NSURL *url2;



            if([urlTwo hasPrefix:@"http://"]){

                url2 = [NSURL URLWithString:urlTwo];

            }else{

                url2 = [NSURL URLWithString:[NSString stringWithFormat:@"http://%@" , urlTwo]];

            }



        NSLog(@"url2:%@", url2);



        NSURLRequest *requestObj = [NSURLRequest requestWithURL:url2];              



        [webView loadRequest:requestObj];



        [[self view] addSubview:webView];



    }

    }



}



@catch (NSException * e) {

    NSLog(@"Exception: %@", e);

    [self alertStatus:@"Login Failed." :@"Login Failed!" :0];

}

}

I had used NSUserDefaults method to save the login credentials but it is not working. Credentials are not saving, again the app is asking for credentials.

try this

when you successfull login then save it in NSUserDefaults

    NSUserDefaults *status=[NSUserDefaults standardUserDefaults];

    [status setObject:@"1" forKey:@"Login"];

Next time only check

       NSUserDefaults *objUserDefaults = [NSUserDefaults standardUserDefaults];       

       NSString *strSuccess=[objUserDefaults objectForKey:@"Login"];



       if ([strSuccess isEqualToString:@"1"]) {

                 // just push the next view.

        }

        else {

             // open login screen

        }

OR Next option, if you care about security, the keychain.

Edit

.h file

  NSUserDefaults *objUserDefaults;

   @property (nonatomic,retain) NSUserDefaults *objUserDefaults;

.m file

    @synthesize objUserDefaults;

Where you first time login Method write this on response

  objUserDefaults = [NSUserDefaults standardUserDefaults]

  [objUserDefaults setObject:@"1" forKey:@"Login"];



   and when you required for login check then



   NSString *strSuccess=[objUserDefaults objectForKey:@"Login"];



   if ([strSuccess isEqualToString:@"1"]) {

             // just push the next view.

    }

    else {

         // open login screen

    }

OrganizationCode is not a string, and you are getting it as a string with this:

OrganizationCode = [[NSUserDefaults standardUserDefaults] stringForKey:@"OrganizationCode"];

You need to use objectForKey: instead, try with that:

OrganizationCode = [[NSUserDefaults standardUserDefaults] objectForKey:@"OrganizationCode"];

And another thing, OrganizationCode seems like the name of a class, not an instance of an object, are you sure you are using it in the right way?

To Store: Login Button:

-(IBAction)Login:(id)sender

{

    if (success) {



        NSUserDefaults *status=[NSUserDefaults standardUserDefaults];

        [status setObject:@"LOGGING" forKey:@"STATUS"];



        // GO TO NEXT FUNCTION ??

    }



}

To Get:Validation Button:

-(void)load_view

{

    NSUserDefaults *status=[NSUserDefaults standardUserDefaults];

    NSString *status_str=[status objectForKey:@"STATUS"];



    if ([status_str isEqualToString:@"LOGGING"]) {

         // GO TO NEXT SUCCESS FUNCTION 

    }

    else

    {

         // GO TO Login View



    }

}
