RN Firebase - How to check if the user accepted the permission for notifications on IOS

Question

根据官方的react-native-firebase 文档，您可以使用ios方法requestPermissions（）来提示用户接受通知，但是由于该方法返回void，我如何检查用户是否拒绝通知？

Looks like the docs incorrectly state that it returns void, it actually returns a promise that resolves with an object - we'll get the docs updated.

On iOS 9 or below, there's no way to tell whether the user accepted or rejected the permissions popup - in this case the object will have a property called status with a value of "unknown"

In all other cases the object will have a granted property which is a boolean value of true/false.

iOS <= 9: https://github.com/invertase/react-native-firebase/blob/master/ios/RNFirebase/messaging/RNFirebaseMessaging.m#L291

iOS >= 10: https://github.com/invertase/react-native-firebase/blob/master/ios/RNFirebase/messaging/RNFirebaseMessaging.m#L302

EDIT: I've updated the docs to reflect the above.
