IOS: global property variable not set even when value is passed to it

I have a set of code that parses an XML file to find a user ID. This identification number is sent to another view controller for a SOAP WSDL request. The problem is that the value is never set.

My two classes are LoginPageViewController and EMIMenuTableViewController.

I am trying to pass an integer value from LoginPageViewController to EMIMenuTableViewController.

Here is the header file for EMIMenuTableViewController:

#import <UIKit/UIKit.h>
@interface EMIMenuTableViewController : UITableViewController
@property (nonatomic) int userNumber;
@end

      

        
        
        
      

    

Here is the header file for LoginPageViewController:

#import <UIKit/UIKit.h>

@interface LoginPageViewController : UIViewController <NSXMLParserDelegate>

{
    NSXMLParser *xmlparser;

    NSString *classelement;
    NSMutableArray *titarry;
    NSMutableArray *linkarray;
    bool itemselected;
    NSMutableString *mutttitle;
    NSMutableString *mutstrlink;
    int userNumber;
    NSString *parsedString;
}

// Username and password text fields
@property (weak, nonatomic) IBOutlet UITextField *usernameTextField;
@property (weak, nonatomic) IBOutlet UITextField *passwordTextField;

// Logging in and registering
- (IBAction)loginButtonSelected:(id)sender;
@property (weak, nonatomic) IBOutlet UIButton *registerButton;

// Unwind segue IBAction for logging out
- (IBAction)logoutAndUnwind:(UIStoryboardSegue *)segue;

@end 

      

        
        
        
      

    

Here the value is set in LoginPageViewController:

- (void)parserDidEndDocument:(nonnull NSXMLParser *)parser {
EMIMenuTableViewController *controller = [[EMIMenuTableViewController alloc] init];
// If the user is authenticated, allow them to proceed with the segue
if([parsedString containsString:@"User Authenticated"]) {

    >>>controller.userNumber = userNumber<<<; - set here
    NSLog(@"User:%d", userNumber);
    [self performSegueWithIdentifier:@"login_success" sender:self];
    NSLog(@"Logged In");

    // If the server says that the user isn't found, notify the user to create an account.
} else if([parsedString containsString:@"User Not Found"]) {

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"User Not Found" message:@"Please create an account!" delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil, nil];
    [alert show];

    // If the server replies that the password is incorrect, notify the user.
} else if([parsedString containsString:@"Password Incorrect"]) {

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Incorrect Username/Password" message:@"Plese try again." delegate:self cancelButtonTitle:@"close" otherButtonTitles:nil, nil];
    [alert show];

} else {

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"An error has occurred!" message:@"Please check your network connection and try again." delegate:self cancelButtonTitle:@"close" otherButtonTitles:nil, nil];
    [alert show];

}

}

      

        
        
        
      

    

Here is the code that shows that the value is not set (this is in the EMIMenuTableViewController):

NSLog(@"User: %d", _userNumber);

      

        
        
        
      

    

Also, here is the console output. You can see the value is set in LoginPageViewController where I registered it, but when registered in EMIMenuTableViewController it is 0.

I figured I was doing it right, but I can't figure out what is wrong. Am I setting a variable incorrectly?

Thank.
