Swift presentViewController

Question

I programmatically have several View controllers in the iOS Swift Project. I do not have storyboards and would like to avoid them if possible. Is there a way to switch to another file viewcontroller.swift (we will call it view2.swift ) and be part of the function that the button calls?
I tried the following:

 let storyboard: UIStoryboard = UIStoryboard(name: "myTabBarName", bundle: nil) let vc: UIViewController = storyboard.instantiateViewControllerWithIdentifier("myVCID") as UIViewController self.presentViewController(vc, animated: true, completion: nil) 

The above works with dropdowns, but I want another view2.swift to be called. It can be done?

Answer 1

Try the following:

 let vc = ViewController() //change this to your class name self.presentViewController(vc, animated: true, completion: nil) 

With Swift3:

 self.present(vc, animated: true, completion: nil) 

Answer 2

For those who get blank / black screens, this code worked for me.

 let vc = self.storyboard?.instantiateViewControllerWithIdentifier("myVCId") as! MyVCName self.presentViewController(vc, animated: true, completion: nil) 

To set the "Identifier" to your VC, simply go to the Identity Inspector for the VC in the storyboard. Set the Storyboard ID to what you need for the ID. Take a look at the image below for reference.

Answer 3

For reference, because this question is one of the first results of Google.

Breach of change in Swift 3:

The presentViewController method presentViewController replaced by the present method.

You can use it like old:

 self.present(viewControllerToPresent, animated: true, completion: nil) 

Example for opening the camera:

 let imagePicker = UIImagePickerController() imagePicker.delegate = self imagePicker.sourceType = UIImagePickerControllerSourceType.camera imagePicker.allowsEditing = false self.present(imagePicker, animated: true, completion: nil) 

Answer 4

Using Swift 2.1 +

  let vc = self.storyboard?.instantiateViewControllerWithIdentifier("settingsVC") as! SettingsViewController self.presentViewController(vc, animated: true, completion: nil) 

Answer 5

For me, I had two views in two separate navigation controllers. I had to use a combination of the above.

 var vc = self.storyboard?.instantiateViewControllerWithIdentifier("WelcomeViewController") as! WelcomeViewController var navigationController = UINavigationController(rootViewController: vc) self.presentViewController(navigationController, animated: true, completion: nil) 

Swift 3.x

  let secondVC = self.storyboard?.instantiateViewController(withIdentifier: "VC-ID" as! yourViewController let navigationVC = UINavigationController(rootViewController: secondVC) self.present(navigationVC, animated: true, completion: nil) 

Answer 6

Swift 3

 let vc = self.storyboard?.instantiateViewController(withIdentifier: "idMyViewControllerName") as! MyViewControllerName self.present(vc, animated: true, completion: nil) 

Answer 7

Just use this: make sure with nibName otherwise the preloaded xib views will not be displayed:

var vc : ViewController = ViewController(nibName: "ViewController", bundle: nil) // change this to your class name

  self.presentViewController(vc, animated: true, completion: nil) 

Answer 8

Solved the black screen by adding a navigation controller and installing the second view controller as rootVC.

 let vc = ViewController() var navigationController = UINavigationController(rootViewController: vc) self.presentViewController(navigationController, animated: true, completion: nil 

Answer 9

You can use the code below:

 var vc = self.storyboard?.instantiateViewControllerWithIdentifier("YourViewController") as! YourViewController; vc.mode_Player = 1 self.presentViewController(vc, animated: true, completion: nil) 

Answer 10

Another possibility is that you do not have the XIB included in your Build object (what happened to me).

This can happen if you have another goal for Dev, Test and Release Builds (which you should have anyway).

Answer 11

You can use the code:

 if let vc = self.storyboard?.instantiateViewController(withIdentifier: "secondViewController") as? secondViewController { let appDelegate = UIApplication.shared.delegate as! AppDelegate appDelegate.window?.rootViewController = vc }
