@react-native-community/push-notification-ios

React Native Push Notification API for iOS.

Getting started

Install

yarn add @react-native-community/push-notification-ios

Link

There are a couple of cases for linking. Choose the appropriate one.

• react-native >= 0.60

The package is automatically linked when building the app. All you need to do is:

cd ios && pod install

• react-native <= 0.59

react-native link @react-native-community/push-notification-ios

• upgrading to react-native >= 0.60

First, unlink the library. Then follow the instructions above.

react-native unlink @react-native-community/push-notification-ios

• manual linking

If you don't want to use the methods above, you can always link the library manually.

Add Capabilities : Background Mode - Remote Notifications

Go into your MyReactProject/ios dir and open MyProject.xcworkspace workspace. Select the top project "MyProject" ans select the "Signing & Capabilities" tab. Add a 2 new Capabilities using "+" button:

• Background Mode capability and tick Remote Notifications.
• Push Notifications capability

Augment AppDelegate

Finally, to enable support for notification and register events you need to augment your AppDelegate.

Update AppDelegate.h

At the top of the file:

#import <UserNotifications/UNUserNotificationCenter.h>

Then, add the 'UNUserNotificationCenterDelegate' to protocols:

@interface AppDelegate : UIResponder <UIApplicationDelegate, RCTBridgeDelegate, UNUserNotificationCenterDelegate>

Update AppDelegate.m

At the top of the file:

#import <RNCPushNotificationIOS.h>

Then, add the following lines:

// Required to register for notifications
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
 [RNCPushNotificationIOS didRegisterUserNotificationSettings:notificationSettings];
}
// Required for the register event.
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
 [RNCPushNotificationIOS didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
}
// Required for the notification event. You must call the completion handler after handling the remote notification.
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
  [RNCPushNotificationIOS didReceiveRemoteNotification:userInfo fetchCompletionHandler:completionHandler];
}
// Required for the registrationError event.
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
 [RNCPushNotificationIOS didFailToRegisterForRemoteNotificationsWithError:error];
}
// IOS 10+ Required for localNotification event
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
didReceiveNotificationResponse:(UNNotificationResponse *)response
         withCompletionHandler:(void (^)(void))completionHandler
{
  [RNCPushNotificationIOS didReceiveNotificationResponse:response];
  completionHandler();
}
// IOS 4-10 Required for the localNotification event.
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
 [RNCPushNotificationIOS didReceiveLocalNotification:notification];
}

Also, if not already present, at the top of the file:

#import <UserNotifications/UserNotifications.h>

And then in your AppDelegate implementation, add the following:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  ...
  // Define UNUserNotificationCenter
  UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
  center.delegate = self;

  return YES;
}

//Called when a notification is delivered to a foreground app.
-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler
{
  completionHandler(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge);
}

Migrating from the core react-native module

This module was created when the PushNotificationIOS was split out from the core of React Native. To migrate to this module you need to follow the installation instructions above and then change you imports from:

import { PushNotificationIOS } from "react-native";

to:

import PushNotificationIOS from "@react-native-community/push-notification-ios";

• register: Fired when the user registers for remote notifications. The handler will be invoked with a hex string representing the deviceToken.
• registrationError: Fired when the user fails to register for remote notifications. Typically occurs when APNS is having issues, or the device is a simulator. The handler will be invoked with {message: string, code: number, details: any}.

---

removeEventListener()

---

requestPermissions()

PushNotificationIOS.requestPermissions([permissions]);

Requests notification permissions from iOS, prompting the user's dialog box. By default, it will request all notification permissions, but a subset of these can be requested by passing a map of requested permissions. The following permissions are supported:

• alert
• badge
• sound

If a map is provided to the method, only the permissions with truthy values will be requested.

This method returns a promise that will resolve when the user accepts, rejects, or if the permissions were previously rejected. The promise resolves to the current state of the permission.

Parameters:

Name	Type	Required	Description
permissions	array	No	alert, badge, or sound

---

abandonPermissions()

PushNotificationIOS.abandonPermissions();

Unregister for all remote notifications received via Apple Push Notification service.

You should call this method in rare circumstances only, such as when a new version of the app removes support for all types of remote notifications. Users can temporarily prevent apps from receiving remote notifications through the Notifications section of the Settings app. Apps unregistered through this method can always re-register.

---

checkPermissions()

PushNotificationIOS.checkPermissions(callback);

See what push permissions are currently enabled.

Parameters:

Name	Type	Required	Description
callback	function	Yes	See below.

callback will be invoked with a permissions object:

• alert :boolean
• badge :boolean
• sound :boolean

---

getInitialNotification()

PushNotificationIOS.getInitialNotification();

This method returns a promise. If the app was launched by a push notification, this promise resolves to an object of type PushNotificationIOS. Otherwise, it resolves to null.

---

constructor()

constructor(nativeNotif);

You will never need to instantiate PushNotificationIOS yourself. Listening to the notification event and invoking getInitialNotification is sufficient.

---

finish()

finish(fetchResult);

This method is available for remote notifications that have been received via: application:didReceiveRemoteNotification:fetchCompletionHandler: https://developer.apple.com/documentation/uikit/uiapplicationdelegate/1623013-application?language=objc

Call this to execute when the remote notification handling is complete. When calling this block, pass in the fetch result value that best describes the results of your operation. You must call this handler and should do so as soon as possible. For a list of possible values, see PushNotificationIOS.FetchResult.

If you do not call this method your background remote notifications could be throttled, to read more about it see the above documentation link.
