Xamarin.iOS中info.plist配置不生效问题求助

Hey Jim, let's work through these two annoying problems you're facing—they're both typical configuration gotchas, so here are some practical steps to resolve them:

1. Screen Orientation Settings Reverting After Saving & Closing #

• Check if your project configuration files are read-only: Right-click your .csproj file (or AndroidManifest.xml if you're working with Android-specific projects) → Properties, then uncheck the "Read-only" box. Sometimes file permissions prevent changes from sticking.
• Verify no conflicting configuration layers: If you modified the orientation in the Debug profile but are opening the Release profile, the settings won't match. Open your .csproj file and search for <ScreenOrientation>—make sure this value aligns with what you set in the UI, and there are no duplicate or overriding entries.
• Do a full clean and rebuild: Deleting bin and obj is a good start, but also go to your IDE's menu → Build → Clean Solution, then Build → Rebuild Solution. This clears any cached build artifacts that might be holding onto old settings.
• Rule out device/simulator settings: If your test device or emulator has auto-rotate enabled or a forced orientation lock, it might override your app's settings. Turn off rotation lock on the device and test again to confirm.

2. Old App Icon Persists After Setting Source to "None" #

• Delete residual icon files manually: Navigate to your platform-specific resource folders (e.g., Platforms/Android/Resources/mipmap-* for MAUI/Xamarin) and delete all old icon files. Even if you set the source to "None", leftover files in these directories will still be picked up by the build system.
• Remove icon references from your project file: Open your .csproj and search for <ApplicationIcon> or <AndroidApplicationIcon>. Ensure this entry is either set to an empty value (<AndroidApplicationIcon></AndroidApplicationIcon>) or completely removed—don't leave it pointing to the old icon path.
• Clear device/simulator app cache: Uninstall the app from your device/emulator, then go to the device's app settings to clear any residual cache (or restart the emulator). Old icons are often cached by the system, so a fresh install after clearing cache will help.
• Reset icon generator cache (if applicable): If you used a built-in icon generator (like MAUI's Icon Manager or Xamarin's Asset Studio), it might have cached the old icon. Re-run the generator (or delete any auto-generated icon files) to ensure no remnants are left.

Give these steps a shot—more often than not, these issues are caused by cached files or conflicting hidden configurations in the project structure. If any step doesn't resolve the problem, we can dive into more specific checks!
