In MvvmCross is there a way to ask the navigation service to close to a specific viewModel?
For example let's say I have 3 view models
A B C
I have navigated from A to B to C.
A -> B -> C
In the C view I press a Done button and would like to go back to view A.
Is there a way to do something like this in the C viewModel?
_navigationService.Close<A>(this);
if you are on Xamarin.Forms (if not let me know and I'll update the answer because it's not that simple), in the IMvxNavigationService you have the ChangePresentation(...) method which uses a hint object to tell the framework what you want to do.
Task<bool> ChangePresentation(MvxPresentationHint hint, CancellationToken cancellationToken = default(CancellationToken));
Here you have the different out-of-the-box hints that the framework provides.
To address your issue you can just use MvxPopPresentationHint:
_navigationService.ChangePresentation(new MvxPopPresentationHint(typeof(A)));
or if A is your root ViewModel, you can just use MvxPopToRootPresentationHint:
_navigationService.ChangePresentation(new MvxPopToRootPresentationHint());
