Summary¶

A ReactiveNavigationController that observes a RoutingState and mirrors its navigation stack into UIKit.

Inherits from: ReactiveNavigationController

Remarks¶

Use RoutedViewHost inside iOS or Mac Catalyst applications to keep push/pop transitions aligned with RoutingState changes. The host resolves views via ViewLocator and updates titles using UrlPathSegment so navigation remains consistent across app restarts.

Setting Router subscribes the host to Navigate, NavigateBack, and NavigationStackChanged. Manual calls to PushViewController and PopViewController also update the router so that imperative navigation cannot desynchronize the stacks.

Provide a ViewContractObservable when multiple views are registered for the same view model. The host will pass the latest contract to ViewLocator so that platform-specific or modal presentations render the correct view controller.

The host asks the view locator for each page's view by the view model's run-time type, without building any type at run time, so it is safe to trim and to compile ahead of time. The default locator checks the view lookup the source generator writes, then the views the app added with Map. A view registered only with the service locator needs RoutedViewHostUnsafe.

Examples¶

<![CDATA[
 var host = new RoutedViewHost
 {
 Router = shell.Router,
 ViewLocator = locator,
 ViewContractObservable = shell.WhenAnyValue(x => x.SelectedContract)
 };
 
 shell.Router.Navigate.Execute(new DashboardViewModel(shell)).Subscribe();
 ]]>
