Move to new view controller after successful login

Question

I am experimenting with developing my first app. I need some help on moving from one view controller to the next after a successful login. I've looked up countless methods but just don't seem to understand. this is what I have so far:

   #import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    credentialsDictionary = [[NSDictionary alloc] initWithObjects:[NSArray arrayWithObjects:@"password", nil] forKeys:[NSArray arrayWithObjects:@"username", nil]];
    
}


- (IBAction)SubmitCredentials;

{
    if ([[credentialsDictionary objectForKey:badgenumberField.text]isEqualToString:passwordField.text]) {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Valid Credentials" message:@"Access Granted." delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];

    }
    else {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Invalid Credentials" message:@"Access Denied." delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];
        [alert show];
        
        
    }
    

;}
@end

Can someone help me get to the next step please it would be greatly appreciated. Can you also let me know what segue i should be using to move to the next controller after the successful login.

After you verify the correct credentials, if you are not using storyboard you should initialize other view controller and them push to it.

something like this:

HomeViewController *ctrl = [[HomeViewController alloc] initWithNibName:[[BaseHomeViewController class] description] bundle:nil]; [self.navigationController pushViewController:ctrl animated:YES];

change HomeViewControllerto the view controller that you wanna move

if you are not using a baseViewController like this:

//  HomeViewController.h

#import "BaseHomeViewController.h"

@interface HomeViewController : BaseHomeViewController

@end

Change the file BaseViewController to your xib view controller class
