请参阅下面 DarkDust 在 Emulating splash video in iOS application 中的回答.

我认为适合您的一种解决方案是显示启动画面 (IMG)，然后播放您喜欢的视频。

要快速播放视频，请使用 AV Foundation https://developer.apple.com/av-foundation/

You cannot get rid of the static splash image. While it is shown, the OS is loading the application and instantiating stuff until it is ready to call your UIApplicationDelegate. So all you can do is either use no splash (black screen for a few seconds) or make your movie start exactly with the shown splash screen so it looks like the static image would suddenly animate.

To get rid of the black screen while the movie loads, you can try to make the player transparent and have an UIImageView behind the player that shows the splash image. The behavior would be this:

Splash screen is shown (static image). Application is loaded. You see the UIImageView, also showing the splash screen. On top of it is the transparent movie player. Movie player finally has loaded the move and starts playing it. At least in theory, this should cause the effect that the static image suddenly starts animating.

But if you don't use a splash screen at all (a lot of games do that), then it doesn't matter that the movie player is showing a black screen at first, you wouldn't notice.

Regarding showing the splash screen in an UIImageView: unfortunately, you have to test the interface rotation and load the image manually, there's no way to query which splash screen was shown. If you only support one interface orientation (again, a lot of games do this) you don't have this problem, of course.
