Xamarin/C# Solution

I had this problem in Xamarin, here is my version of @micromanc3r's solution:

public class PageViewControllerDataSource : UIPageViewControllerDataSource
{
    UIViewController[] pages;

    public PageViewControllerDataSource(UIViewController[] pages)
    {
        this.pages = pages;
    }

...

    public override nint GetPresentationIndex(UIPageViewController pageViewController)
    {
        return Array.IndexOf(pages, pageViewController.ViewControllers[0]);
    }
}
