Question

I’m trying to save a String from a textfield.

I have a

IBOutlet UITextField *login;
IBOutlet UITextField *pass;
... 

@synthesize login,pass;
...

When I’m clicking to a button, this method is running :

- (IBAction) saveAuthentication: (id)sender {

    //show an error message
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Login et Mot de passe" message:@"Votre login et votre mot de passe sont enregistrés."delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];
    [alert show];[alert release];

    //extract the login from the field and put in in Log
        NSString *loginsaved = login.text;
    NSString *passsaved = pass.text;
        NSLog(@"%d", loginsaved );

        //save the login and pass in the phone
        NSUserDefaults *pref = [NSUserDefaults standardUserDefaults];
    [pref setObject:login.text forKey:@"login"];
    [pref setObject:pass.text forKey:@"pass"];

}

When I execute it, The Console show me 0 instead of the login that I’ve typed…

a hundred of thanx for the help

For NSString variable You should use below code…

 NSString *loginsaved = login.text;
 NSString *passsaved = pass.text;
 NSLog(@"%@", loginsaved );

Here in objective
for Integer %d, String %@, Float %f is used.
