# Popup 彈出層

### 介绍

彈出層容器，用於展示彈窗、信息提示等內容

### 安裝

```tsx
import { Popup } from '@nutui/nutui-react-native';
```

## 代碼演示

### 基礎用法

`visible` 控製顯示/隱藏

:::demo

```tsx
import React, { useState } from "react";
import { Popup, Cell } from '@nutui/nutui-react-native';

const App = () => {
  const [showBasic, setShowBasic] = useState(false);
  return (
    <>
        <Cell title="展示彈出層" isLink onClick={() => { setShowBasic(true) }}/>
        <Popup visible={ showBasic } style={{ padding: 30 }} onClose={ () => { setShowBasic(false) } }>正文</Popup>
    </>
  );
};
export default App;
```

### 彈出位置

:::demo

```tsx
import React, { useState } from "react";
import { Popup, Cell } from '@nutui/nutui-react-native';

  const [showLeft, setShowLeft] = useState(false);
  const [showRight, setShowRight] = useState(false);

  return (
    <>
        <Cell title="頂部彈出" isLink onClick={() => { setShowTop(true) }}/>
        <Cell title="底部彈出" isLink onClick={() => { setShowBottom(true) }}/>
        <Cell title="左側彈出" isLink onClick={() => { setShowLeft(true) }}/>
        <Cell title="右側彈出" isLink onClick={() => { setShowRight(true) }}/>
        <Popup visible={ showTop } style={{ height: '20%' }} position="top" onClose={ () => { setShowTop(false) } } />
        <Popup visible={ showBottom } style={{ height: '20%' }} position="bottom" onClose={ () => { setShowBottom(false) } } />
        <Popup visible={ showLeft } style={{ width: '20%', height: '100%' }} position="left" onClose={ () => { setShowLeft(false) } } />
        <Popup visible={ showRight } style={{ width: '20%', height: '100%' }} position="right" onClose={ () => { setShowRight(false) } } />
    </>
  );
