ios - 应用启动动画怎么实现

Question

很多游戏的应用启动画面是一个视频，左上角哪里有一个跳过按钮，我想知道这个是怎么实现的？
另外，这种方法疑似不太好看，我可否像播放GIF那样，把启动的Default.png做成动态图片，或者至少是动态图片的效果？有没有什么方案？

If the splash screen is a video, it is very simple to implement. After the app is started, play a video and then add a skip button on it.

A more feasible solution is that you can first display the animation written in the program, and then put the remaining initialization work into GCD:

dispatch_async(dispatch_get_main_queue(, ^{
// other initial codes
});

P.S. I remember looking at lastfm’s code in 2010, and found that the startup animation of its ios client was really powerful: I directly made 68 screenshots of the logo animation, and then used UIImageView’s animationImages to play it frame by frame. In fact, this is also a way~
