Xamarin iOS

In order to use bindings in the View, you must first implement IViewFor<TViewModel> on your View. Depending on the platform, you must implement it differently:

  • iOS - change your base class to one of the Reactive UIKit classes (i.e. ReactiveUIViewController) and implement ViewModel using RaiseAndSetIfChanged, or implement INotifyPropertyChanged on your View and ensure that ViewModel signals changes.
public partial class NotificationsListViewController : ReactiveTableViewController, IViewFor<NotificationsListViewModel>
{
    public NotificationsListViewController()
    {
    }

    public override void ViewDidLoad()
    {
        base.ViewDidLoad();
        ViewModel = new NotificationsListViewModel();
        // ... view stuff
    }

    NotificationsListViewModel _ViewModel;
    public NotificationsListViewModel ViewModel
    {
        get { return _ViewModel; }
        set { this.RaiseAndSetIfChanged(ref _ViewModel, value); }
    }

    object IViewFor.ViewModel
    {
        get { return _ViewModel; }
        set { ViewModel = (NotificationsListViewModel)value; }
    }
}
