react-native-icloud-key-value-store 📱☁️📱

This is a fork of https://github.com/manicakes/react-native-icloudstore

Usage

In your target's "capabilities" tab in Xcode, make sure that iCloud is switched on as well as make sure that the "Key-value storage" option is checked.

react-native-icloudstore mimicks the same promise-based API as AsyncStorage. In addition to all of the AsyncStorage methods, there is one additional feature: a native event (iCloudStoreDidChangeRemotely) that lets you know when your store changed due to a remote change (i.e. from another device on the same iCloud account). See the example below for a very basic way to make use of that in your React Native application. For apps that use redux, you may want to call an appropriate action creator upon receiving the event.

import { NativeEventEmitter } from 'react-native';
import iCloudStorage from 'react-native-icloud-key-value-store';

...

  componentWillMount() {
    this.eventEmitter = new NativeEventEmitter(iCloudStorage);
    this.eventEmitter.addListener('iCloudStoreDidChangeRemotely', this.loadData);
  }

  componentWillUnmount() {
    this.eventEmitter.remove();
  }

  loadData = (userInfo) => {
    const changedKeys = userInfo.changedKeys;
    if (changedKeys != null && changedKeys.includes('MY_STORAGE_KEY')) {
      iCloudStorage.getItem('MY_STORAGE_KEY').then(result => this.setState({ storage: result }));
    }
  }
  
...
