Access to AuthorizationStatus on iOS

[artdevgame]

Hello 👋🏻

Other push notification libraries give us access to the AuthorizationStatus (or something similar) that allows us to determine if the user has previously seen the permission dialog and accepted/denied notifications, or if they haven't seen them at all.

I need this functionality in my app as I like to show an info card before requesting permissions in the UI.

This is the functionality we have exposed at the moment:

// boolean
const isRegisteredForPush = await Notifications.isRegisteredForRemoteNotifications(); 

/*
export interface NotificationPermissionOptions {
    carPlay?: boolean;
    criticalAlert?: boolean;
    providesAppNotificationSettings?: boolean;
    provisional?: boolean;
    announcement?: boolean;
}
export interface NotificationPermissions extends NotificationPermissionOptions {
    badge: boolean;
    alert: boolean;
    sound: boolean;
    notificationCenter: boolean;
    lockScreen: boolean;
}
*/

// NotificationPermissions
const permissions = await Notifications.ios.checkPermissions();

I'm incapable of determining an undetermined state 😄

if (!isRegisteredForPush) {
	// is this because they denied access or because they haven't seen the permission dialog yet?
}

if (!permissions.alert && !permissions.provisional) {
	// is this because we don't have the necessary permissions, or because they haven't seen the permission dialog yet?
}

Here's an example of how @firebase-react-native/messaging expose it:
https://github.com/invertase/react-native-firebase/blob/49d5bedea52683fa98db5f90d3243fe770c4cad5/packages/messaging/lib/index.d.ts#L461

And another from @react-native-community/push-notification-ios:
https://github.com/react-native-push-notification/ios/blob/88b49f9b548825df9e74ebcf582a9320742c7d54/index.d.ts#L11

I would like it exposed both as a type and const so I can use it both for type-checking and assignment.

Hey @artdevgame, your users will see the dialog only after you'll operate Notifications.registerRemoteNotifications(). So you can know if you did that before, no?
You may save a boolean whether you asked it in a storage like @react-native-community/async-storage.
I think the reason we don't have it is because Android lacks it. But it can be a nice PR someday 😃

@DanielEliraz I didn't think to use local-storage to work around the issue, yep, that will work, thanks!
