How to switch between NSViewControllers using NSPageController?

Question

I was not lucky to find any examples on the Internet that exactly match what I'm trying to do. I am trying to use NSPageControllerto view and switch between several NSPageControllers. My steps.

• I am creating a new fast OS X project
• I add an object to ViewControllerand make it from a class NSPageController.
• I add two buttons: one is a "Next" label, and the other is a "Back" label for transitions.
• I bind buttons to an object NSPageControllerlike navigateForward and navigateBack.
• I create an output in a custom class NSViewControllerfor the object NSPageControllerand add special delegate methods NSPageController.

• I add two additional view controllers to the storyboard and create an identifier for them for the link in my custom controller class of the form: Wizard1, Wizard2.

  import Cocoa

  class ViewController: NSViewController, NSPageControllerDelegate {

  @IBOutlet var myPageController: NSPageController!
  override func viewDidLoad() {
      super.viewDidLoad()
      let vc1: AnyObject? = self.storyboard!.instantiateControllerWithIdentifier("Wizard1")
      let vc2: AnyObject? = self.storyboard!.instantiateControllerWithIdentifier("Wizard2")
      self.myPageController.arrangedObjects.append(vc1!)
      self.myPageController.arrangedObjects.append(vc2!)
      // Do any additional setup after loading the view.
  }
  override init?(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) {
      myPageController = NSPageController()
      super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil?)
  }
  
   required init?(coder aDecoder: NSCoder) {
  myPageController = NSPageController()
  super.init(coder:aDecoder)
  }
  
  override var representedObject: AnyObject? {
      didSet {
      // Update the view, if already loaded.
      }
  }
  
  func pageController(pageController: NSPageController, identifierForObject object: AnyObject!) -> String! {
      return "View"
  }
  
  func pageController(pageController: NSPageController, viewControllerForIdentifier identifier: String!) -> NSViewController! {
      let vc1: AnyObject? = self.storyboard!.instantiateControllerWithIdentifier("Wizard1")
      return vc1 as NSViewController
  
  }
  func pageController(pageController: NSPageController, prepareViewController viewController: NSViewController!, withObject object: AnyObject!) {
      viewController.representedObject = object
  }
  func pageControllerDidEndLiveTransition(pageController: NSPageController) {
      pageController.completeTransition()
  }
  func pageControllerWillStartLiveTransition(pageController: NSPageController) {
  self.presentViewControllerAsModalWindow(self.storyboard?.instantiateControllerWithIdentifier("Wizard2") as NSViewController)
  
  }
  

  }

-[NSNib initWithNibNamed:bundle:] could not load the nibName: NSPageController in bundle (null).

Answer 1

Perhaps you are trying to load a thread with the wrong name in AppDelegate.mor wherever you initialize your page controller.

Otherwise, you skipped creating the .xib file and name it NSPageController. When creating a Cocoa Touch Class, there is a checkbox to also create an xib file for your class, if necessary.

:

myPageController = NSPageController()

, . NSViewController , . "NSPageController".
