在iOS应用程序中未调用MvvmCross中的SaveState [英] SaveState in MvvmCross is not being called in an iOS application

问题描述

我正在使用MvvmCross v3.5来构建iOS应用程序.每当应用程序进入后台时，我都希望在视图模型中调用SaveState.

I am using MvvmCross v3.5 to build an iOS application. Whenever the application goes into the background I am expecteing SaveState to be called in the view model.

但是它永远不会被调用.我已经在模拟器和设备上都尝试过了.我错过了什么吗?

However it never gets called. I have tried this both on the simulator and a device. Am I missing something.

这在该应用的Android版本中有效，因此我认为我已正确设置了它.

This works in the Android version of the app, so I think I have set it up correctly.

还有其他人遇到过这个问题吗?任何帮助将不胜感激.

Has anyone else got this issue? Any help would be appreciated.

推荐答案

我认为在Xamarin中，您需要实现UIApplicationDelegate.ShouldRestoreApplicationState和ShouldSaveApplicationState以返回true.

I think in Xamarin you need to implement UIApplicationDelegate.ShouldRestoreApplicationState and ShouldSaveApplicationState to return true.
