React Native Permissions

Request user permissions from React Native (iOS only - android coming soon)

The current supported permissions are:

  • Push Notifications
  • Location
  • Camera
  • Microhone
  • Photos
  • Contacts
  • Events
  • Reminders
  • Bluetooth (Peripheral role. Don’t use for Central only)
  • Background Refresh

General Usage

const Permissions = require('react-native-permissions');

//...
  //check the status of a single permission
  componentDidMount() {
    Permissions.getPermissionStatus('photo')
      .then(response => {
        //response is one of: 'authorized', 'denied', 'restricted', or 'undetermined'
        this.setState({ photoPermission: response })
      });
  }

  //request permission to access photos
  _requestPermission() {
    Permissions.requestPermission('photo')
      .then(response => {
        //returns once the user has chosen to 'allow' or to 'not allow' access
        //response is one of: 'authorized', 'denied', 'restricted', or 'undetermined'
        this.setState({ photoPermission: response })
      });
  }

  //check the status of multiple permissions
  _checkCameraAndPhotos() {
    Permissions.checkMultiplePermissions(['camera', 'photo'])
      .then(response => {
        //response is an object mapping type to permission
        this.setState({ 
          cameraPermission: response.camera,
          photoPermission: response.photo,
        })
      });
  }

  // this is a common pattern when asking for permissions.
  // iOS only gives you once chance to show the permission dialog, 
  // after which the user needs to manually enable them from settings.
  // the idea here is to explain why we need access and determine if
  // the user will say no, so that we don't blow our one chance.
  // if the user already denied access, we can ask them to enable it from settings.
  _alertForPhotosPermission() {
    Alert.alert(
      'Can we access your photos?',
      'We need access so you can set your profile pic',
      [
        {text: 'No way', onPress: () => console.log('permission denied'), style: 'cancel'},
        this.state.photoPermission == 'undetermined'? 
          {text: 'OK', onPress: this._requestPermission.bind(this)}
          : {text: 'Open Settings', onPress: Permissions.openSettings}
      ]
    )
  }
//...

API

Permission statuses - authorized, denied, restricted, or undetermined

Permission types - location, camera, microphone, photo, contacts, event, reminder, bluetooth, notification, or backgroundRefresh

Method Name Arguments Notes
getPermissionStatus type - Returns a promise with the permission status. Note: for type location, iOS AuthorizedAlways and AuthorizedWhenInUse both return authorized
requestPermission type - Accepts any permission type except backgroundRefresh. If the current status is undetermined, shows the permission dialog and returns a promise with the resulting status. Otherwise, immediately return a promise with the current status. Note: see below for special cases
checkMultiplePermissions [types] - Accepts an array of permission types and returns a promise with an object mapping permission types to statuses
getPermissionTypes none - Returns an array of valid permission types
openSettings none - Switches the user to the settings page of your app (iOS 8.0 and later)
canOpenSettings none - Returns a boolean indicating if the device supports switching to the settings page

Note: Permission type bluetooth represents the status of the CBPeripheralManager . Note: Don’t use this if you’re only using CBCentralManager

Special cases

requestPermission also accepts a second parameter for types location and notification.

  • location: the second parameter is a string, either always or whenInUse(default).
  • notification: the second parameter is an array with the desired alert types. Any combination of alert, badge and sound (default requests all three) example

    Permissions.requestPermission('location', 'always')
      .then(response => {
        this.setState({ locationPermission: response })
      })
    
    Permissions.requestPermission('notification', ['alert', 'badge'])
      .then(response => {
        this.setState({ notificationPermission: response })
      })
    

Setup

npm install --save react-native-permissions

iOS

  • Run open node_modules/react-native-permissions
  • Drag ReactNativePermissions.xcodeproj into the Libraries group of your app’s Xcode project
  • Add libReactNativePermissions.a to `Build Phases -> Link Binary With Libraries.
