Xamarin iOS - Load Storyboard Reference Programatically

Question

I have 2 storyboards: Activities.storyboard and Contacts.storyboard.

On Contacts.storyboard I have a ViewController: ContactDetails.

On Activities.storyboard I need refer the ContactDetails in Contacts.storyboard

I created a Storyboard Reference on Activities.storyboard and referenced the ContactDetails.

And I tried load this View Controller programmatically

var viewController = Storyboard.InstantiateViewController(nameof(ContactDetails));
NavigationController.PushViewController(viewController, true);

But I didn't work to load programmatically as a normal View Controller

Foundation.MonoTouchException: Objective-C exception thrown. Name: NSInvalidArgumentException Reason: Storyboard () doesn't contain a view controller with identifier 'ContactDetails'

I know it works this way:

var storyboard = UIStoryboard.FromName(nameof(Contact), null);
var viewController = storyboard.InstantiateViewController(nameof(ContactDetails));
NavigationController.PushViewController(viewController, true);

But I want to use a Reference View Controller, is it possible?

Answer 1

Apparently the only way to load Storyboard Reference is with Segue.

Programmatically the only way is instantiate the Storyboard and after instantiate the ViewController

Like this:

var storyboard = UIStoryboard.FromName(nameof(Contact), null);
var viewController = storyboard.InstantiateViewController(nameof(ContactDetails));
NavigationController.PushViewController(viewController, true);
