How to call perform segue method from another class?

Question

I want to perform segue from View B to View C and I am calling method in class A. My segue method in Class B is-

//ViewController B


func nextViewAction() -> Void  {
        self.performSegueWithIdentifier("nextview", sender: self)
    }

And I am calling it in Class A like this-

//ViewController A



@IBAction func sideMenuAction(sender: AnyObject) {

        ViewClassB().nextViewAction()
}

But it crashing- Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver () has no segue with identifier 'nextview''

Have you set the name nextview for the segue between Controller B and Controller C? You can check by clicking on the segue between the two controllers, and then checking the Identifier value in the Attributes Inspector.

Are you able to share the project with me so that I can take a look to see what is going on? – Fahim Apr 06 '17 at 06:47

What you can have is move to the third viewcontroller from first viewcontroller by skipping the second one use the code below..

class MyViewController: UIViewController, UINavigationControllerDelegate {

var viewControllerToInsertBelow : UIViewController?

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationController?.delegate = self
}

func pushTwoViewControllers() {
    if let viewController2 = self.storyboard?.instantiateViewControllerWithIdentifier("id1"),
        let viewController3 = self.storyboard?.instantiateViewControllerWithIdentifier("id2") { //change this to your identifiers
            self.viewControllerToInsertBelow = viewController2
            self.navigationController?.pushViewController(viewController3, animated: true)
    }
}

//MARK: - UINavigationControllerDelegate
func navigationController(navigationController: UINavigationController, didShowViewController viewController: UIViewController, animated: Bool) {
    if let vc = viewControllerToInsertBelow {
        viewControllerToInsertBelow = nil
        let index = navigationController.viewControllers.indexOf(viewController)!
        navigationController.viewControllers.insert(vc, atIndex: index)
    }
}

}

keep remember, I am not using `UINavigationController` at all — iDeveloper, Apr 06 '17 at 08:58

I think you cannot trigger segue action from AViewController because what performSegue does is that :

Initiates the segue with the specified identifier from the current view controller's storyboard file.

Try implementing segue from A to C
