react native camera 使用

1. 安装
   npm install --save react-native-camera@git+https://[email protected]/react-native-community/react-native-camera.git
   2.自动link
   react-native link react-native-camera
   3.ios配置权限
   info.plist里配置camera访问权限及提示信息
   4.安卓自动配置后有问题
   检查android/app/build.gradle:

android {
  ...
  defaultConfig {
    ...
    missingDimensionStrategy 'react-native-camera', 'general' <-- insert this line
  }
}
