The SearchApi
module gives you a general React Native interface to interact with the iOS Search API, Core Spotlight.
For more information about iOS Search APIs, see https://developer.apple.com/ios/search/.
npm install react-native-search-api --save
react-native link
To the top of your AppDelegate.m
add the following line:
#import "RCTSearchApiManager.h"
In your AppDelegate implementation add the following:
- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray * _Nullable))restorationHandler {
return [RCTSearchApiManager application:application continueUserActivity:userActivity restorationHandler:restorationHandler];
}
Subscribe to the search item open events in your components like this:
componentDidMount() {
<...>
SearchApi.addOnSpotlightItemOpenEventListener(this.handleOnSpotlightItemOpenEventListener);
SearchApi.addOnAppHistoryItemOpenEventListener(this.handleOnAppHistoryItemOpenEventListener);
}
To prevent memory leaks don't forget to unsubscribe:
componentWillUnmount() {
<...>
SearchApi.removeOnSpotlightItemOpenEventListener(this.handleOnSpotlightItemOpenEventListener);
SearchApi.removeOnAppHistoryItemOpenEventListener(this.handleOnAppHistoryItemOpenEventListener)
}
In order to create a new spotlight item, use indexSpotlightItem
or indexSpotlightItems
:
SearchApi.indexSpotlightItem(item).then(result => {
console.log('Success');
}).catch(err => {
console.log('Error: ' + err);
});
To add new items to the app history, use createUserActivity
:
SearchApi.indexAppHistoryItem(item).then(result => {
console.log('Success');
that.setState({labelText: 'Success'});
}).catch(err => {
console.log('Error: ' + err);
that.setState({labelText: ('Error: ' + err)});
});
