#iOS 1、导入项目RCTLSScan 2、在主项目info.plist文件中添加 //相机 NSCameraUsageDescription cameraDesciption //通讯录 NSContactsUsageDescription contactsDesciption //麦克风 NSMicrophoneUsageDescription microphoneDesciption //相册 NSPhotoLibraryUsageDescription photoLibraryDesciption 其中string值可以随意些

#Android

1. 添加项目引用，在android/setting.gradle中:

   include ':react-native-LSScanVC' project(':react-native-LSScanVC').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-LSScanVC/android')

2.在android/app/build.gradle中：

dependencies {

compile fileTree(dir: "libs", include: ["*.jar"])

compile project(':react-native-LSScanVC')//二维码扫描
}

3. 添加package:

• 使用startReactApplication

  //MainActivity import android.os.Bundle; import com.facebook.react.ReactInstanceManager; import com.facebook.react.ReactRootView; import com.facebook.react.shell.MainReactPackage;

  import com.dowin.qrcode.BarcodeScannerPackage;//二维码扫描

  private ReactInstanceManager mReactInstanceManager; private ReactRootView mReactRootView;

  @Override protected void onCreate(Bundle savedInstanceState) {

   super.onCreate(savedInstanceState);
  
   mReactRootView = new ReactRootView(this);
   mReactInstanceManager = ReactInstanceManager.builder()
            .setApplication(getApplication())
            .setBundleAssetName("index.android.bundle")
            .setJSMainModuleName("index.android")
            .addPackage(new MainReactPackage())
           .addPackage(new BarcodeScannerPackage(this))//二维码扫描
            .setUseDeveloperSupport(true)
            .setInitialLifecycleState(LifecycleState.RESUMED)
            .build();
  
   Bundle options = new Bundle();
   //
   mReactRootView.startReactApplication(mReactInstanceManager, getMainComponentName(), options);
  

  }

• setReactNativeHost

  import android.os.Bundle; import com.facebook.react.ReactInstanceManager; import com.facebook.react.ReactRootView; import com.facebook.react.shell.MainReactPackage;

  import com.dowin.qrcode.BarcodeScannerPackage;//二维码扫描

  import com.facebook.react.ReactNativeHost; import com.facebook.react.ReactPackage; import java.util.Arrays; import java.util.List;

  @Override protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    MainApplication application = (MainApplication) getApplication();
             application.setReactNativeHost(new ReactNativeHost(application) {
                 @Override
                 protected boolean getUseDeveloperSupport() {
                     return false;
                 }
             
                 @Override
                 protected List<ReactPackage> getPackages() {
                     return Arrays.<ReactPackage>asList(
                             new MainReactPackage(),
                             new BarcodeScannerPackage(MainActivity.this),//二维码扫描
                     );
                 }
             });
  

  } //MainApplication public void setReactNativeHost(ReactNativeHost mReactNativeHost) { this.mReactNativeHost = mReactNativeHost; }

4. AndroidManifest.xml

#使用

const LSScan = NativeModules.LSScan;

LSScan.openLsScan().then(r=> {
                },e=>{
                });

#生成二维码使用规则 #iOS 1、react-native link react-native-LSScanVC 2、import QRCodeApi from 'react-native-LSScanVC/QRCode'; 3、

iOS新增长按识别功能

//长按识别 关键字为"information" _onchange(event){ console.info('成功识别',event.information); }

#v 1.0.1

import com.eguma.barcodescanner.BarcodeScannerPackage; 修改为 import com.dowin.qrcode.BarcodeScannerPackage; 添加保存二维码 QRCodeApi.saveImage();

#v 1.0.2 添加条码生成 属性：paymentCode #v 1.0.3 添加二维码扫描 <LSScanApi descText="请将下方矩形框对准包装或设备上的二维码进行识别扫描" onChange={(e)={ console.info(e.information); } />
