Xamarin iOS 布局更改后添加启动屏幕 storyboard

Question

I inherited an old xamarin codebase. It launches in this strange windowed form with top and bottom black bars (pictured below). It also uses a launch image. As soon as I start using a launch storyboard, the app becomes fullscreen (no top/bottom black bars), and as a result, all the layout is messed up.

Does anyone know how to have the launch storyboard without removing the black bars?

Answer 1

Not really, this is a feature.

Apple says, "Your app will run in Full Screen Display Mode on iPhone X, iPhone XS, iPhone XS Max, and iPhone XR if your project's base SDK is set to iOS 11 or later and you have a Launch Storyboard or iPhone X launch image."

So you adding the storyboard triggers the app to run in full screen mode.
