相机未在 React-native-qr-code-scanner 中授权

Question

Not able to see camera in React-native-qr-code-scanner, instead of camera it is showing camera not authorized text. I am using the same code which is there in npm react native qr code scanner documentation. I have tested in many devices.

Answer 1

I encountered the same problem it's last days......

1/ npm uninstall react-native-camera
2/ install a specific version of react-native-camera like this: npm install react-native-camera@1.10.1
3/the version in your package.json should look like this: "react-native-camera": "1.10.1"
4/ re-test

this has worked for me.

You can solve this issue in iOS by doing the following

1. Change the versions

"react-native-qrcode-scanner": "^1.5.4",
"react-native-permissions": "^3.0.5",
"react-native-camera": "3.44.3",

2. Info.plist

<key>NSCameraUsageDescription</key>
<key>NSPhotoLibraryUsageDescription</key>

3. Pod file

permissions_path = '../node_modules/react-native-permissions/ios'
  pod 'Permission-Camera', :path => "#{permissions_path}/Camera"
  pod 'react-native-camera', :path => '../node_modules/react-native-camera'

4. yarn and pod install

Build app again it will work
