In my first view controller I have 3 input fields each of them take the user input into and saves it into a string such as: address, username and password as NSUserDefaults. This part works fine. In my second view controller I'm trying to take the 3 strings from first controller (address, username and password) create a html link based on the 3 strings. I've tried many ways to access the 3 strings with no luck, the result I get is NULL. Here is my code:

//.h file - first view controller with the 3 input fields CamSetup.h

 #import <UIKit/UIKit.h>
 @interface CamSetup : UIViewController <UITextFieldDelegate> 
 {
    NSString * address;
    NSString * username;
    NSString * password;

    IBOutlet UITextField * addressField;
    IBOutlet UITextField * usernameField;
    IBOutlet UITextField * passwordField; 
 }

 -(IBAction) saveAddress: (id) sender;
 -(IBAction) saveUsername: (id) sender;
 -(IBAction) savePassword: (id) sender;

 @property(nonatomic, retain) UITextField *addressField;
 @property(nonatomic, retain) UITextField *usernameField;
 @property(nonatomic, retain) UITextField *passwordField; 
 @property(nonatomic, retain) NSString *address; 
 @property(nonatomic, retain) NSString *username; 
 @property(nonatomic, retain) NSString *password;

 @end

//.m file - first view controller CamSetup.m

#import "CamSetup.h"

@interface CamSetup ()
@end

@implementation CamSetup
@synthesize addressField, usernameField, passwordField, address, username, password;

-(IBAction) saveAddress: (id) sender
{
address = [[NSString alloc] initWithFormat:addressField.text];
[addressField setText:address];
NSUserDefaults *stringDefaultAddress = [NSUserDefaults standardUserDefaults];
[stringDefaultAddress setObject:address forKey:@"stringKey1"];
NSLog(@"String [%@]", address);
}

-(IBAction) saveUsername: (id) sender
{
  username = [[NSString alloc] initWithFormat:usernameField.text];
  [usernameField setText:username];
  NSUserDefaults *stringDefaultUsername = [NSUserDefaults standardUserDefaults];
  [stringDefaultUsername setObject:username forKey:@"stringKey2"];
  NSLog(@"String [%@]", username);
}

-(IBAction) savePassword: (id) sender
{
  password = [[NSString alloc] initWithFormat:passwordField.text];
  [passwordField setText:password];
  NSUserDefaults *stringDefaultPassword = [NSUserDefaults standardUserDefaults];
  [stringDefaultPassword setObject:password forKey:@"stringKey3"];
  NSLog(@"String [%@]", password);
}

- (void)viewDidLoad
{   
[addressField setText:[[NSUserDefaults standardUserDefaults] objectForKey:@"stringKey1"]];
[usernameField setText:[[NSUserDefaults standardUserDefaults] objectForKey:@"stringKey2"]];
[passwordField setText:[[NSUserDefaults standardUserDefaults] objectForKey:@"stringKey3"]];

[super viewDidLoad];
}

@end

//.h second view controller LiveView.h

 #import <UIKit/UIKit.h>
 #import "CamSetup.h"
 @interface LiveView : UIViewController
 {
  NSString *theAddress;
  NSString *theUsername;
  NSString *thePassword;
  CamSetup *camsetup; //here is an instance of the first class
}
@property (nonatomic, retain) NSString *theAddress;
@property (nonatomic, retain) NSString *theUsername;
@property (nonatomic, retain) NSString *thePassword;

@synthesize theAddress, theUsername, thePassword;

- (void)viewDidLoad
{
  [super viewDidLoad]; 
  theUsername = camsetup.username; //this is probably not right?
  NSLog(@"String [%@]", theUsername); //resut here is NULL
  NSLog(@"String [%@]", camsetup.username); //and here NULL as well
}
@end
