does it closed and re-open?

how to keep the Page1(or other pages) when I open another app in my mobile?

Answer 1

This issue occurs because iOS has strict memory management policies. If your app is moved to the background and iOS needs to free up resources, it may terminate your app. When you return, the app is relaunched, and by default, it starts from the initial page (home page) as the navigation stack is not preserved.

To keep the state of Page1 (or other pages) and maintain the navigation stack when returning to your app, you need to implement state persistence in your .NET MAUI app.

Answer 2

iOS may close your app when it goes to the background due to system memory management. When you return, the app restarts at the home page.

To keep Page1 when switching apps:

1. Save the current page when the app goes to the background:

      protected override void OnSleep() { var state = Shell.Current.GetNavigationState(); Preferences.Set("AppState", state); }
      
      
   

2. Restore the page when the app restarts:

      protected override void OnStart() { if (Preferences.ContainsKey("AppState")) { var state = Preferences.Get("AppState", string.Empty); Shell.Current.SetNavigationState(state); } }
      
      
   

This ensures the user returns to the last page they were on.
