| # React Native QRCodeLocalImage (remobile) | ||
| A local qrcode image parse for react-native, support for ios and android | ||
|
|
||
| ## Installation | ||
| ```sh | ||
| npm install @remobile/react-native-qrcode-local-image --save | ||
| ``` | ||
| ### Installation (iOS) | ||
| * Drag RCTQRCodeLocalImage.xcodeproj to your project on Xcode. | ||
| * Click on your main project file (the one that represents the .xcodeproj) select Build Phases and drag libRCTQRCodeLocalImage.a from the Products folder inside the RCTQRCodeLocalImage.xcodeproj. | ||
| * Look for Header Search Paths and make sure it contains $(SRCROOT)/../../../react-native/React as recursive. | ||
|
|
||
| ### Installation (Android) | ||
| ```gradle | ||
| ... | ||
| include ':react-native-qrcode-local-image' | ||
| project(':react-native-qrcode-local-image').projectDir = new File(settingsDir, '../node_modules/@remobile/react-native-qrcode-local-image/android') | ||
| ``` | ||
|
|
||
| * In `android/app/build.gradle` | ||
|
|
||
| ```gradle | ||
| ... | ||
| dependencies { | ||
| ... | ||
| compile project(':react-native-qrcode-local-image') | ||
| } | ||
| ``` | ||
|
|
||
| * register module (in MainApplication.java) | ||
|
|
||
| ```java | ||
| ...... | ||
| import com.remobile.qrcodeLocalImage.RCTQRCodeLocalImagePackage; // <--- import | ||
|
|
||
| ...... | ||
|
|
||
| @Override | ||
| protected List<ReactPackage> getPackages() { | ||
| ...... | ||
| new RCTQRCodeLocalImagePackage() // <------ add here | ||
| ...... | ||
| } | ||
|
|
||
| ``` | ||
|
|
||
| ## Usage | ||
|
|
||
| ### Example | ||
| ```js | ||
| 'use strict'; | ||
|
|
||
| var React = require('react'); | ||
| var ReactNative = require('react-native'); | ||
| var { | ||
| StyleSheet, | ||
| View, | ||
| Text, | ||
| } = ReactNative; | ||
|
|
||
| var Button = require('@remobile/react-native-simple-button'); | ||
| var QRCode = require('@remobile/react-native-qrcode-local-image'); | ||
|
|
||
|
|
||
| module.exports = React.createClass({ | ||
| getInitialState() { | ||
| return {text: ''} | ||
| }, | ||
| onPress() { | ||
| QRCode.decode(!app.isandroid?'/Users/fang/Desktop/qr.png':'/sdcard/qr.png', (error, result)=>{ | ||
| this.setState({text: JSON.stringify({error, result})}); | ||
| }); | ||
| }, | ||
| render() { | ||
| return ( | ||
| <View style={styles.container}> | ||
| <Button onPress={this.onPress}>测试</Button> | ||
| <Text> | ||
| {this.state.text} | ||
| </Text> | ||
| </View> | ||
| ); | ||
| } | ||
| }); | ||
|
|
||
|
|
||
| var styles = StyleSheet.create({ | ||
| container: { | ||
| flex: 1, | ||
| backgroundColor: 'transparent', | ||
| justifyContent: 'space-around', | ||
| paddingVertical: 150, | ||
| }, | ||
| }); | ||
| ``` | ||
|
|
||
| ### method | ||
