☝🏼 React Native Permissions
Request user permissions from React Native, iOS + Android
2.0.0 is on it's way! A bit of help is needed here!
| Version | React Native Support | | ------- | -------------------- | | 1.2.0+ | 0.52.0+ |
Setup
npm install --save react-native-permissions @react-native-community/async-storage
# --- or ---
yarn add react-native-permissions @react-native-community/async-storage
⚠️ To install @react-native-community/async-storage
, please refers to the package documentation.
📌 Don't forget to add permissions to AndroidManifest.xml
for android and Info.plist
for iOS (Xcode >= 8). See iOS Notes or Android Notes for more details.
Additional iOS setup
Using cocoaPods
Update the following line with your path to node_modules/
and add it to your podfile:
pod 'ReactNativePermissions', :path => '../node_modules/react-native-permissions'
Using react-native link
react-native link react-native-permissions
Using manual linking
- In the XCode's "Project navigator", right click on your project's Libraries folder ➜
Add Files to <…>
- Go to
node_modules
➜react-native-permissions
➜ selectReactNativePermissions.xcodeproj
- Add
libReactNativePermissions.a
toBuild Phases
->Link Binary With Libraries
Using
import Permissions from 'react-native-permissions';
// OR const Permissions = require('react-native-permissions').default
// if you use CommonJS module system
// …
export default class extends React.Component {
// …
// Check the status of a single permission
componentDidMount() {
Permissions.check('photo').then(response => {
// Response is one of: 'authorized', 'denied', 'restricted', or 'undetermined'
this.setState({photoPermission: response});
});
}
// Request permission to access photos
_requestPermission = () => {
Permissions.request('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.checkMultiple(['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}
: {text: 'Open Settings', onPress: Permissions.openSettings},
],
);
}
// …
}
API
Permissions statuses
Promises resolve into one of these statuses:
| Return value | Notes |
| -------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| authorized
| User has authorized this permission |
| denied
| User has denied this permission at least once. On iOS this means that the user will not be prompted again. Android users can be prompted multiple times until they select 'Never ask me again' |
| restricted
| iOS - this means user is not able to grant this permission, either because it's not supported by the device or because it has been blocked by parental controls. Android - this means that the user has selected 'Never ask me again' while denying permission |
| undetermined
| User has not yet been prompted with a permission dialog |

Methods
| Method Name | Arguments | Notes |
| ------------------- | --------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| check()
| type
| - Returns a promise with the permission status. See iOS Notes for special cases |
| request()
| 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. See iOS Notes for special cases |
| checkMultiple()
| [types]
| - Accepts an array of permission types and returns a promise with an object mapping permission types to statuses |
| getTypes()
| none | - Returns an array of valid permission types |
| openSettings()
| none | - (iOS only - 8.0 and later) Switches the user to the settings page of your app |
| canOpenSettings()
| none | - (iOS only) Returns a boolean indicating if the device supports switching to the settings page |
iOS Notes
- Permission type
bluetooth
represents the status of theCBPeripheralManager
. Don't use this if you only needCBCentralManager
. - Permission type
location
accepts a second parameter forrequest()
andcheck()
; the second parameter is a string, eitheralways
orwhenInUse
(default). - Permission type
notification
accepts a second parameter forrequest()
. The second parameter is an array with the desired alert types. Any combination ofalert
,badge
andsound
(default requests all three). - If you are not requesting mediaLibrary then you can remove MediaPlayer.framework from the xcode project.
// example
Permissions.check('location', {type: 'always'}).then(response => {
this.setState({locationPermission: response});
});
Permissions.request('location', {type: 'always'}).then(response => {
this.setState({locationPermission: response});
});
Permissions.request('notification', {type: ['alert', 'badge']}).then(
response => {
this.setState({notificationPermission: response});
},
);
- You cannot request microphone permissions on the simulator.
- With Xcode 8, you now need to add usage descriptions for each permission you will request. Open Xcode ➜
Info.plist
➜ Add a key (starting with "Privacy - …") with your kit specific permission.
Example: If you need Contacts permission you have to add the key Privacy - Contacts Usage Description
.
App Store submission disclaimer
If you need to submit your application to the AppStore, you need to add to your Info.plist
all *UsageDescription
keys with a string value explaining to the user how the app uses this data. Even if you don't use them.
So before submitting your app to the App Store, make sure that in your Info.plist
you have the following keys:
<key>NSBluetoothPeripheralUsageDescription</key>
<string>Some description</string>
<key>NSCalendarsUsageDescription</key>
<string>Some description</string>
<key>NSCameraUsageDescription</key>
<string>Some description</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>Some description</string>
<key>NSPhotoLibraryAddUsageDescription</key>
<string>Some description</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>Some description</string>
<key>NSSpeechRecognitionUsageDescription</key>
<string>Some description</string>
<key>NSAppleMusicUsageDescription</key>
<string>Some description</string>
<key>NSMotionUsageDescription</key>
<string>Some description</string>
This is required because during the phase of processing in the App Store submission, the system detects that you app contains code to request the permission X
but don't have the UsageDescription
key and then it rejects the build.
Please note that it will only be shown to the users the usage descriptions of the permissions you really require in your app.
You can find more information about this issue in #46.
Android Notes
- Uses React Native's own
PermissionsAndroid
JS API. - All required permissions also need to be included in the
AndroidManifest.xml
file before they can be requested. Otherwiserequest()
will immediately returndenied
. - You can request write access to any of these types by also including the appropriate write permission in the
AndroidManifest.xml
file. here. e.g.<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
Read more here.
- The optional rationale argument will show a dialog prompt.
// example
Permissions.request('camera', {
rationale: {
title: 'Cool Photo App Camera Permission',
message:
'Cool Photo App needs access to your camera ' +
'so you can take awesome pictures.',
},
}).then(response => {
this.setState({cameraPermission: response});
});
- Permissions are automatically accepted for targetSdkVersion < 23 but you can still use
check()
to check if the user has disabled them from Settings.
Troubleshooting
Q: iOS - App crashes as soon as I request permission
A: Starting with Xcode 8, you need to add permission descriptions. See iOS notes for more details. Thanks to @jesperlndk for discovering this.
Q: iOS - App crashes when I change permission from settings
A: This is normal. iOS restarts your app when your privacy settings change. Just google "iOS crash permission change".
