React Native Permissions

Check user permissions (iOS only)

What

Some iOS features require the user to grant permission before you can access them.

This library lets you check the current status of those permissions. (Note: it doesn’t prompt the user, just silently checks the permission status)

The current supported permissions are:

• Location
• Camera
• Microhone
• Photos
• Contacts
• Event
• Bluetooth (Peripheral role. Don’t use for Central only)
• RemoteNotifications (Push Notifications)

Example

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

//....
  componentDidMount() {
    Permissions.locationPermissionStatus()
    .then(response => {
      if (response == Permissions.StatusUndetermined) {
        console.log("Undetermined");
      } else if (response == Permissions.StatusDenied) {
        console.log("Denied");
      } else if (response == Permissions.StatusAuthorized) {
        console.log("Authorized");
      } else if (response == Permissions.StatusRestricted) {
        console.log("Restricted");
      }
    });
  }
//...

API

As shown in the example, methods return a promise with the authorization status as an int. You can compare them to the following statuses: StatusUndetermined, StatusDenied, StatusAuthorized, StatusRestricted

locationPermissionStatus() - checks for access to the user’s current location. Note: AuthorizedAlways and AuthorizedWhenInUse both return StatusAuthorized

cameraPermissionStatus() - checks for access to the phone’s camera

microphonePermissionStatus() - checks for access to the phone’s microphone

photoPermissionStatus() - checks for access to the user’s photo album

contactsPermissionStatus() - checks for access to the user’s address book

eventPermissionStatus(eventType) - requires param eventType; either reminder or event. Checks for access to the user’s calendar events and reminders

bluetoothPermissionStatus() - checks the authorization status of the CBPeripheralManager (for sharing data while backgrounded). Note: Don’t use this if you’re only using CBCentralManager

notificationPermissionStatus() - checks if the user has authorized remote push notifications. Note: iOS only tells us if the user has ever registered for notification, and which notifications are enabled. Therefore we cannot tell the difference between a user who has never been prompted for notification and a user who denied permission; both will return StatusUndetermined. You can determine if StatusUndetermined is actually StatusDenied by keeping track of whether or not you’ve already asked the user for permission. This promise can return StatusDenied if the user switched notifications off from the settings menu. Confusing, I know…

backgroundRefreshStatus() - checks the authorization status of background refresh

You also can open the Settings app. openSettings() - open the Settings app. Note: this is only supported in ios >= 8. You can use canOpenSettings() to determine if it’s supported.
