Xamarin.Forms Prism中特定于平台的代码

Question

I have a custom control and I need to use platform specific code inside it. I register platform specific implementation in IPlatformInitializer s on each platform. And I'm able to resolve instance via IUnityContainer . But I haven't reference to unity container inside my custom control. What is the designed approach by framework developers to resolve registered instance inside my custom control? I create my control in XAML .

With Xamarin.Forms 's approach I'm able to do:

DependencyService.Get<ISomeManager>();

from any place of an application.

Thanks in advance.

You will need to implement a service locator pattern in order to access the container in your custom control. You can cast the Application.Current to a PrismApplication and use the Container property off of it, or expose a new static property for the container.
