npm install react-qr-reader ``` 然后,可以在React组件中使用`QrReader`组件来实现扫码操作: ```jsx import React, { useState } from 'react'; import QrReader from 'react-qr-reader'; const QRCodeScanner = () => { const [result, setResult] = useState(''); const handleScan = (data) => ...

When set to false, when a QR code is scanned, the QRCodeScanner will not scan another code until it is re-rendered. When set to true this will reactivate the scanning ability of the component.reactivateTimeout propType: number default: 0...
In continuous scan mode, we can draw QR code overlays to show which QR codes are detected. We can do this using SVG which has been discussed in a previous article. Add an SVG element in JSX: const [viewBox,setViewBox] = useState("0 0 1920 1080"); //... <svg viewBox={viewBox...
下面开始上业务功能代码:可直接新建一个ScanQRCode.js文件把代码拷贝进去。后续直接引用该组件即可。 import { RNCamera } from 'react-native-camera' import React, { useCallback, useState } from 'react'; import { StyleSheet, Animated, View,
