SecViewController *sec = [[SecViewController alloc] init];
[self.navigationController pushViewController:sec animated:NO];

}

Why is it so?

Answer 1

Change your code as following :

SecViewController *sec = [self.storyboard instantiateViewControllerWithIdentifier:@"viewControllerIdentifier"];

[self.navigationController pushViewController:sec animated:NO];

Change viewControllerIdentifier as your storyboard identifier for that view controller ..

Hope it helps..
