# 安全区域

在移动浏览器中，内容有时会因为状态栏或主页指示器等系统 UI 而被遮挡。Apps in Toss SDK 为了防止这种情况，提供了一个以像素为单位计算屏幕安全区域（Safe Area）间距值的函数。

尤其是在 iPhone X 及以上设备或部分 Android 设备上，使用全屏的网页应用时，系统 UI 经常会遮挡内容。使用下面的函数，就能轻松调整间距，让内容安全显示。

### `useSafeAreaInsets`

为了防止在移动浏览器中内容被状态栏或主页指示器等系统 UI 遮挡的问题，它会以像素单位计算屏幕安全区域（Safe Area）的间距值。 `useSafeAreaInsets` 可在使用 ReactNative 开发时使用。

```tsx
import { useSafeAreaInsets } from '@granite-js/native/react-native-safe-area-context';
const { top: safeAreaTop, right: safeAreaRight } = useSafeAreaInsets();
// 导航栏顶部间距：safeAreaTop
// 导航栏右侧间距：safeAreaRight + 10
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developers-apps-in-toss.toss.im/documentation/api-and-sdk-zh/react-native/screen-navigation/safe-area.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
