Problems with storyboard in iOS

Question

Two interfaces are set up in the storyboard.

Use

in your code

[self.navigationController pushViewController:[[SCMainViewController alloc]init] animated:YES];

How to jump to the past without loading

Can't we use pure code to jump anymore? . Can I only use segue?

Answer 1

 UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"xxx" bundle:nil];
 SCMainViewController *vc = [storyboard instantiateViewControllerWithIdentifier:NSStringFromClass([SCMainViewController class])];
 [self.navigationController pushViewController:vc animated:YES];

Answer 2

You can jump and feel your Stroyboard 上相对应的 ViewController 没有关联 Class - SCMainViewController.

Answer 3

id loadViewControllerFromStoryboard(NSString *name,NSString *identifier)
{
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:name bundle:nil];
    UIViewController *vc = nil;
    
    if (identifier == nil)
    {
        vc = [storyboard instantiateInitialViewController];
    }
    else
    {
        vc = [storyboard instantiateViewControllerWithIdentifier:identifier];
    }
    
    if ([vc isKindOfClass:[UIViewController class]]) {
        return vc;
    }
    return nil;
}
