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,
1、npm install react-native-camera--save2、react-nativelink react-native-camera 在这里link很可能会失败,我试了好几次,没能成功,接下来进行手动配置: IOS: 1、导入RNCamera.xcodeproj 在Xcode中打开ios项目看一下Libraries里面有没有RNCamera.xcodeproj,如果没有右键Libraries->add Files to Demo,在弹出框中...

A QR code is a two-dimensional barcode that’s designed to be quickly read by any computer camera. In this tutorial, we create a QR-code-reading application based on RNCamera which will be able to read QR codes in real time and render their content to the screen at the time of detect...
