i'm trying to present viewcontroller programmatically in storyboard, i'm using the below mentioned code but it's not working, doesn't give me any response...

- (void)buttonPressed
{
NSLog(@"called");

UIStoryboard *sb = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil];

UINavigationController *vc = [sb instantiateViewControllerWithIdentifier:@"123"];

vc.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;

[self.navigationController presentModalViewController:vc animated:YES];
}

what am i missing here?

NSLog(@"called");

    UIStoryboard *sb = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];

    UINavigationController *vc = [sb instantiateInitialViewController];

    vc.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
    [self presentViewController:vc animated:YES completion:nil];
