问题
I'd like to request permissions on one page instead of waiting for each particular situation. However, I do not want multiple popups. Is there a way to ask for permissions with a single popup/modal.
On the android side I found this post and this, which look promising, but I have yet to find something for iOS.

In Android
First add permissions in to the AndroidManifest.xml file and then
if (Platform.OS === 'android') {
PermissionsAndroid.requestMultiple(
[PermissionsAndroid.PERMISSIONS.CAMERA,
PermissionsAndroid.PERMISSIONS.READ_CONTACTS,
PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION,
PermissionsAndroid.PERMISSIONS.ACCESS_COARSE_LOCATION,
PermissionsAndroid.PERMISSIONS.READ_EXTERNAL_STORAGE,
PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE]
).then((result) => {
if (result['android.permission.ACCESS_COARSE_LOCATION']
&& result['android.permission.CAMERA']
&& result['android.permission.READ_CONTACTS']
&& result['android.permission.ACCESS_FINE_LOCATION']
&& result['android.permission.READ_EXTERNAL_STORAGE']
&& result['android.permission.WRITE_EXTERNAL_STORAGE'] === 'granted') {
this.setState({
permissionsGranted: true
});
} else if (result['android.permission.ACCESS_COARSE_LOCATION']
|| result['android.permission.CAMERA']
|| result['android.permission.READ_CONTACTS']
|| result['android.permission.ACCESS_FINE_LOCATION']
|| result['android.permission.READ_EXTERNAL_STORAGE']
|| result['android.permission.WRITE_EXTERNAL_STORAGE'] === 'never_ask_again') {
this.refs.toast.show('Please Go into Settings -> Applications -> APP_NAME -> Permissions and Allow permissions to continue');
}
});
}
In iOS In the info section of your project on XCode
Add the permissions and the description say - ex: Privacy - Contacts Usage Description then,
Permissions.request('photo').then(response => { if (response === 'authorized') { iPhotoPermission = true; } Permissions.request('contact').then(response => { if (response === 'authorized') { iPhotoPermission = true; } }); });

Makes sure you also add respective permissions in manifest file as well.
export async function GetAllPermissions() {
try {
if (Platform.OS === "android") {
const userResponse = await PermissionsAndroid.requestMultiple([
PermissionsAndroid.PERMISSIONS.READ_CONTACTS,
PermissionsAndroid.PERMISSIONS.CALL_PHONE
]);
return userResponse;
}
} catch (err) {
Warning(err);
}
return null;
}

To request multiple permissions I will suggest you to use npm module as its saves time and easy to setup and most important you don't have to worry about the platforms :)
Installation
npm install --save react-native-permissions
Usage
import Permissions from 'react-native-permissions'
// 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,
})
})
}
Don't forget to add permissions to AndroidManifest.xml for android and Info.plist for iOS (Xcode >= 8).
