iOS Navigation RootView 설정

1. AppDelegate 방식

1-1 Infoplist에서 Manifest 삭제

1-2 SceneDelegate 클래스 삭제

 

1-3 AppDelegate에서 두 함수 삭제

 

 

1-4 AppDelegate에서 var window: UIWindow? 추가

 

 

1-5 didFinishLaunchingWithOptions 함수에 코드 추가

 

## ObjC 문법

 UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
 MainViewController *MainViewController = [storyboard instantiateViewControllerWithIdentifier:@"MainViewController"];
 UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController: MainViewController];
 self.window.rootViewController = nav;
 [nav setNavigationBarHidden:YES animated:YES];
 [self.window makeKeyAndVisible];

1. SceneDelegate 방식

 

1-1 willConnectTo 함수에 코드 추가

guard let scene = (scene as? UIWindowScene) else { return }
        
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "ViewController") as! ViewController
let rootViewController = UINavigationController(rootViewController: vc)
rootViewController.isNavigationBarHidden = true
self.window = UIWindow(windowScene: scene)
self.window?.rootViewController = rootViewController
self.window?.makeKeyAndVisible()

2. Test

1. ViewController 방식

let storyboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "FirstViewController") as! FirstViewController
self.navigationController?.pushViewController(vc, animated: true)

2. Xib 방식
