I created a derived navigation controller with a xib file. Use the designer to create a button on the navigation bar and followed the steps to link the control to a variable. Run the application and button is null in C#.

So the problem here is that in the Xib there's no relation between the navigation controller and the view controller.

It might be possible to have both the navigation controller and the view controller inside the same xib but honestly but that's a. not recommended by Apple, b. not how xibs should be used (more of a single view/controller type of thing).

All the examples you will find that use Xibs and navigation controllers will have a NavigationController set in code:

In your AppDelegate you'd do this:

// Initialize the UINavigationController with a custom ViewController directly
// (that's the missing link that your Xib is not doing, hence why you can't see the button item)
var navigationController = new UINavigationController (new MyViewController ());

window.RootViewController = navigationController;

However in general, especially since it's now 2017, I'd recommend using storyboard for navigation controller (;

In storyboards it's totally fine to have multiple view controllers and segues are the way to link one to another.

See: https://developer.xamarin.com/guides/ios/user_interface/introduction_to_storyboards/

Also the Master-Detail default iOS template is a good start.

This is not a bug with Xamarin.iOS though so I'm closing it.
