🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

139-141: 建议完善 FAQ 内容

为了使文档更加清晰和实用，建议：

1. 添加具体的代码示例，展示如何实现样式的添加和移除
2. 解释在 iOS 上出现此问题的原因
3. 说明此问题影响的 iOS 版本范围

建议按如下方式扩展内容：

 ## FAQ
 
-在 iOS 下，有时候 `lockScroll` 可能不生效，此刻在打开 `popup` 时，可将宿主页面的样式增加 `overflow: hidden;`，关闭弹层时，再重置样式。
+### iOS 下 lockScroll 失效问题
+
+在 iOS 系统中，某些版本下 `lockScroll` 属性可能会失效。这是由于 iOS WebView 对 overflow 处理机制的特殊性导致的。
+
+#### 解决方案
+
+可以通过手动控制宿主页面的样式来解决此问题：
+
+```tsx
+const App = () => {
+  const [visible, setVisible] = useState(false)
+  
+  const handlePopupOpen = () => {
+    document.body.style.overflow = 'hidden'
+    setVisible(true)
+  }
+  
+  const handlePopupClose = () => {
+    document.body.style.overflow = 'auto'
+    setVisible(false)
+  }
+  
+  return (
+    <Popup
+      visible={visible}
+      onOpen={handlePopupOpen}
+      onClose={handlePopupClose}
+    >
+      弹窗内容
+    </Popup>
+  )
+}
+```
