描述
Description
When KeyboardAvoidingView inside a ScrollView and focus a TextInput the app crashes (goes extremely slow).
This seems to only happen if the KeyboardAvoidingView needs to trigger the animation, if the ScrollView is small it works fine.
Testing with react native 0.72.9 the issue doesn't seem to happen
Steps to reproduce
- install the app
yarn ios - Using the simulator make sure the keyboard shows when entering a text input
- Focus a text input and start typing on the keyboard
- Dismiss the keyboard / click outside of the input
- You will notice the app has now hung

调研方向
从链接的 KeyboardAvoidingViewExample 复现器开始,在 iOS 上使用 React Native 0.73.4,并在 ScrollView 内使用 KeyboardAvoidingView,复现卡死问题。检查 KeyboardAvoidingView 与 ScrollView 的交互,重点关注反复触发的 UIManager.configureNextLayoutAnimation 回调,并将其行为与 React Native 0.72.9 进行比较。当关闭键盘不再导致应用卡死或累积待处理回调时,即表示完成。
