Programmatically navigate to another view controller/scene

Question

I got an error message during navigating from first view controller to second view controller. My coding is like this one

let vc = LoginViewController(nibNam         


        

Answer 1

If you want to navigate to Controller created Programmatically, then do this:

let newViewController = NewViewController()
self.navigationController?.pushViewController(newViewController, animated: true)

If you want to navigate to Controller on StoryBoard with Identifier "newViewController", then do this:

let storyBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let newViewController = storyBoard.instantiateViewController(withIdentifier: "newViewController") as! NewViewController
        self.present(newViewController, animated: true, completion: nil)

Answer 2

let VC1 = self.storyboard!.instantiateViewController(withIdentifier: "MyCustomViewController") as! ViewController
let navController = UINavigationController(rootViewController: VC1)
self.present(navController, animated:true, completion: nil)

Answer 3

I think you are looking for something like this:

let signUpViewController = SignUpViewController()
present(signUpViewController, animated: true, completion: nil)

If you want full screen of the new page:

present(signUpViewController, animated: true, completion: nil)

Hope this helps :)

Answer 4

Try this one. Here "LoginViewController" is the storyboardID specified in storyboard.

See below

let secondViewController = self.storyboard?.instantiateViewControllerWithIdentifier("LoginViewController") as LoginViewController
self.navigationController?.pushViewController(secondViewController, animated: true)

Answer 5

XCODE 8.2 AND SWIFT 3.0

Present an exist UIViewController

let loginVC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "LoginViewController") as! LoginViewController
self.present(loginVC, animated: true, completion: nil)

Push an exist UIViewController

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

Remember that you can put the UIViewController Identifier following the next steps:

• Select Main.storyboard
• Select your UIViewController
• Search the Utilities in the right
• Select the identity inspector
• Search in section identity "Storyboard ID"
• Put the Identifier for your UIViewController

Answer 6

See mine.

func actioncall () {
    let loginPageView = self.storyboard?.instantiateViewControllerWithIdentifier("LoginPageID") as! ViewController
    self.navigationController?.pushViewController(loginPageView, animated: true)
}

If you use presenting style, you might lose the page's navigation bar with preset pushnavigation.
