描述
Description
After upgrading to expo 52 and react-native 0.76.3 I noticed some of my dashed borders had disappeared in some cases on iOS. On further investigation, I discovered that dashed borders no longer work when borderStyle: "dashed" | "dotted" are used in combination with overflow: "hidden" or overflow: "scroll". Instead of a dashed or dotted border, it shows a solid border.
Dotted and dashed borders work correctly with overflow: "visible"
Dotted and dashed borders also work correctly in android.
I took a cursory look through the source code, but couldn't see the issue - that being said, if someone can point me in somewhat the right direction, I'd be happy to take a swing at a fix.
Steps to reproduce
- Install the application and launch ios emulator
- look at the code in the stylesheet for the two items
- look at the missing borderStyle

调研方向
从链接的 borderIssue reproducer 开始,比较 overflow: hidden 或 scroll 与 visible 时 iOS 对虚线和点线边框的渲染效果。跟踪 React Native iOS 边框渲染路径,确定这些情况下边框变为实线的原因。当虚线和点线边框在受影响的 overflow 值下能够正确渲染,且不会导致 Android 或 visible overflow 行为发生回归时,即视为完成。
