objective-c - IOS开发，点击app Icon启动慢，是什么原因？

Question

IOS开发，点击appIcon启动慢，做的几个APP全部有这个问题，有时候启动要好几秒，有时候又正常，这个需要在哪里做优化啊？体验略差啊

Answer 1

Go and take a look at the startup code

Answer 2

This is quite normal and has something to do with the system. For example, after you have just finished playing a game, it will be slower to open the app again.

Also, if you do too many things in appDelegate and it takes too long, it will be slow. For example, using jsPatch and runAfterFetch is obviously slower.
