How to change initial View Controller?

Question

Objective-C

Good afternoon, I have a login form in the application, I need to change the intial View Controller in the storyboard after user authorization. That is, after authorization, the initial page would not be a login form, a user profile.

Answer 1

The best way would be to initialize the view controller not through the storyboard, but in the method

- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

You can pull the controller out of the storyboard, or make two different storyboards, one for the login/registration screens and the other for the application itself. In this case, the main storyboard is the first one, but if there is no user data, use the second one.

Answer 2

1) In the Storyboard , provide the association ID between the authorization controller and the user profile.
2) In authorization controller, if user is authorized, use
- performSegueWithIdentifier:sender:

Answer 3

I took the advice of ManWithBear and made this sketch

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        
        let storyboard = UIStoryboard(name: "Main", bundle: NSBundle.mainBundle())
        let logined = true
        var vc: UIViewController?
        if !logined {
            vc = storyboard.instantiateViewControllerWithIdentifier("loginVC")
        } else {
            vc = storyboard.instantiateInitialViewController()
        }
        window = UIWindow(frame: UIScreen.mainScreen().bounds)
        window?.rootViewController = vc
        window?.makeKeyAndVisible()
        return true
    }
