ReactNativeBarcodeScanner

Implemented a barcode scanner with support of react native technology

Some screen shots here:

Getting started (TBV)

1. npm install ReactNativeBarcodeScanner@latest --save
2. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
3. Go to node_modules ➜ ReactNativeBarcodeScanner and add ReactNativeBarcodeScanner.xcodeproj
4. In XCode, in the project navigator, select your project. Add libReactNativeBarcodeScanner.a to your project's Build Phases ➜ Link Binary With Libraries
5. Click ReactNativeBarcodeScanner.xcodeproj in the project navigator and go the Build Settings tab. Make sure 'All' is toggled on (instead of 'Basic'). Look for Header Search Paths and make sure it contains both $(SRCROOT)/../react-native/React and $(SRCROOT)/../../React - mark both as recursive.
6. Run your project (Cmd+R)

Usage

All you need is to require the BarcodeScanner module and then use the <BarcodeScanner/> tag.

var BarcodeScanner = require('./BarcodeScanner');
var {
  AlertIOS,
  AppRegistry,
  Component,
  NavigatorIOS,
  StyleSheet,
  Text,
  TouchableHighlight,
  View,
} = React;

var ReactNativeBarcodeScanner = React.createClass({
  getInitialState: function() {
    return {
      value: ''
    };
  },
  render: function() {
    return (
      <View style={styles.container}>
        <TouchableHighlight onPress={this._switchCamera}>
          <View>
            <BarcodeScanner
              ref="scanner"
              aspect="Fill"
              type="Back"
              orientation="Portrait"
              onScanned={this._onScannedResult}
              style={styles.barcode}
            />
          </View>
        </TouchableHighlight>
        <TouchableHighlight onPress={this._stopScaning}>
          <Text>Stop Scaning</Text>
        </TouchableHighlight>
        <TouchableHighlight onPress={this._startScaning}>
          <Text>Start Scaning</Text>
        </TouchableHighlight>
      </View>
    );
  },
  _switchCamera: function() {
    this.refs.scanner.switch();
  },
  _stopScaning: function() {
    this.refs.scanner.stopScanning();
  },
  _startScaning: function() {
    this.refs.scanner.startScanning();
  },
  _onScannedResult: function(data) {
    console.log(data);
    if (this.state.value === '') {
      this.setState({value: data});
      AlertIOS.alert(this.state.value);
    }
    this.props.navigator.pop();
  }
});

Thanks to Loch Wansbrough (@lwansbrough) for the react-native-camera module which provided me with a great example of how to set up this module.
