Description
React Native pressables don't seem to prevent the touches from being forwarded to the OS. This results in unexpected behavior in some situations.
e.g. on iPadOS, there is a large area at the top of the screen that can be tapped to scroll to the top. This area usually covers a similar height to the header bar. If headers have buttons that use pressables, the pressable handles the action, but iPadOS also handles the touch and scrolls any scrollview in the screen to the top.
This does not happen when using a native control (e.g., with UIControl), and only happens with React Native's Pressable. It is very common to add custom buttons to the header (even when using native stack and native header), many people also use custom headers. So the unexpected scroll to top results in a bad UX.
I'm not aware of a way to prevent this behavior right now.
Steps to reproduce
- Install the app on iPad simulator with
yarn ios - Scroll the scrollview so it's not at the top
- Click on the button in the header
- Observe that the button also scrolls the scrollview to the top

贡献指南
从这里开始
- 先读完整个 Issue,再读项目的贡献指南。
- 在 Issue 下留言说明你要接手 —— 这能避免两个人做同样的事。
- Fork 仓库,在一个分支上完成修改。
- 提交 Pull Request,并在描述里引用这个 Issue 编号。
调研方向
先从 https://github.com/satya164/iPadTouchableRepro 中的必需 reproducer 开始,复现 issue 中描述的 iPadOS 行为,然后跟踪 Pressable 的 iOS 触摸处理。未指定源文件或测试;完成标准是激活 Pressable 后不再同时触发 iPadOS 的滚动到顶部行为,同时 native controls 不受影响。
