问题
I have an application that needs a model view on top of a modal view but the presenter MvxModalSupportTouchViewPresenter doesn't support it. Is there any reason for this before I set out on extending it?
回答1:
The default mvx presenters are there to provide basic presentation. If you need custom functionality then please do create your own presenter logic. See the conference sample for an example - ir reroutes navigation through a tab controller.
I anticipate that many phone and especially tablet apps will make their own presenters.
Please also see the recent discussion on showing a navigation bar within the modal presentation - MvvmCross Using a modal ViewController from a Tab
Hope that helps
