Do you know why this is happening and most important how to fix it? Adding the key with what value?
回答1:
Starting in tvOS 10 you must include a wide top shelf image, Top Shelf Image Wide, with a size of 2320px by 720px @1x. tvOS Human Interface Guidelines: Icons and Images.
If Top Shelf Image Wide is not already in your Assets.xcassets you can create one manually, or with the + Add a Group or Image Set button. For example:
The crop area is still 1920px x 720px @1x when the top shelf image is displayed on the Apple TV. So, if you're using any text or images that you don't want cut off make sure to make them centered in those dimensions. For example:
The areas in red are only used for sliding in your top shelf image when your app icon becomes highlighted on the Apple TV home screen.
EDIT:
Check your target's Build Settings.
