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(nibName: "LoginViewController", bundle: nil)
self.navigationController?.pushViewController(vc, animated: true)

The problem is I always got this kind of error message

Solution 1

I already found the answer

Swift 4

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

Swift 3

let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)

let nextViewController = storyBoard.instantiateViewControllerWithIdentifier("nextView") as NextViewController
self.presentViewController(nextViewController, animated:true, completion:nil)

Solution 2

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)

Solution 3

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

Solution 4

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)

Solution 5

Swift3:

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

Try this out. You just confused nib with storyboard representation.

You need to add a LoginViewController.xib file in your project. When you create LoginViewController.swift, make sure include xib is selected.

[gabbler]

Try to add a complete new view controller and substitute LoginViewController and see if it works.

[Nurdin]

BTW, I'm using storyboard

[gabbler]

Me too, I am using storyboard and used your code to load a xib file and it worked for me.

[Noah]

To access a storyboard in your code, you need to set its Story Board ID in your storyboard.

[Michael Brown]

From within a ViewController, you can access the storyboard using self.StoryBoard

[DanielZanchi]

it hides the "navigation bar"

[Fever]

@Danny182 If you want navigation bar to show, use self.navigationController?.pushViewController(nextViewContro‌​ller, animated: true)

[Sparrow]

You need to add some content around your answer and explain it a little bit.

[Louis Langholtz]

Is there any introduction or explanation you can think of for the code in your answer? Perhaps a first sentence like "I think you want code like this:".

[Allison]

I was surprised that Nurdin's answer was suggested to work (and it didn't) because it was just calling push. This of course LOOKS like it should work since we're dealing with the navigation controller

[Yucel Bayram]

True answer, i voted up but why we need "Restoration ID" ? I believe "Storyoard ID" is enough for this situation.

[Cristian Mora]

Thank for your feedback @yucelbayram A restoration identifier is a string that you need to assign to any view controller or view that you want preserved and restored. In my case, i use this field because i need for determinate function however if you isn't need it can you remove.

[Lucas]

It should be storyboard

[kiran]

What if its have UINavigationController tag to UITabbarViewController how to push UINavigationController in that case?

[Jonas Deichelmann]

Thank you. I tried to use the method for a xib, instead I needed the one for a Storyboard. Your answer helped me a lot!

It(Swift 4) presents the new view controller modally
