@biosensics/push-notification-ios v1.0.0

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

React Native Push Notification API for iOS.

Getting started

Install

Using npm:

npm i @react-native-community/push-notification-ios --save

or using Yarn:

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

Link

React Native v0.60+

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

npx pod-install

For android, the package will be linked automatically on build.

React Native <= v0.59

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" and 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 <UserNotifications/UserNotifications.h>
#import <RNCPushNotificationIOS.h>

Then, add the following lines:

// 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];
}
// Required for localNotification event
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
didReceiveNotificationResponse:(UNNotificationResponse *)response
         withCompletionHandler:(void (^)(void))completionHandler
{
  [RNCPushNotificationIOS didReceiveNotificationResponse:response];
}

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(UNNotificationPresentationOptionSound | UNNotificationPresentationOptionAlert | UNNotificationPresentationOptionBadge);
}

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';

How to determine push notification user click

Receiving remote pushes has two common cases: user dismissed notification and user clicked notification. To have separate logic for each case you can use notification.getData().userInteraction to determine push notification user click:

export const App = () => {
  const [permissions, setPermissions] = useState({});

  useEffect(() => {
    PushNotificationIOS.addEventListener('notification', onRemoteNotification);
  });

  const onRemoteNotification = (notification) => {
    const isClicked = notification.getData().userInteraction === 1;

    if (isClicked) {
      // Navigate user to another screen
    } else {
      // Do something else with push notification
    }
  };
};

How to perform different action based on user selected action.

export const App = () => {
  const [permissions, setPermissions] = useState({});

  /**
   * By calling this function, notification with category `userAction` will have action buttons
   */
  const setNotificationCategories = () => {
    PushNotificationIOS.setNotificationCategories([
      {
        id: 'userAction',
        actions: [
          {id: 'open', title: 'Open', options: {foreground: true}},
          {
            id: 'ignore',
            title: 'Desruptive',
            options: {foreground: true, destructive: true},
          },
          {
            id: 'text',
            title: 'Text Input',
            options: {foreground: true},
            textInput: {buttonTitle: 'Send'},
          },
        ],
      },
    ]);
  };

  useEffect(() => {
    PushNotificationIOS.addEventListener('notification', onRemoteNotification);
  });

  const onRemoteNotification = (notification) => {
    const actionIdentifier = notification.getActionIdentifier();

    if (actionIdentifier === 'open') {
      // Perform action based on open action
    }

    if (actionIdentifier === 'text') {
      // Text that of user input.
      const userText = notification.getUserText();
      // Perform action based on textinput action
    }
  };
};

Methods

presentLocalNotification()

PushNotificationIOS.presentLocalNotification(details);

Deprecated - use addNotificationRequest instead. Schedules the localNotification for immediate presentation.

Parameters:

details is an object containing:

• alertBody : The message displayed in the notification alert.
• alertAction : The "action" displayed beneath an actionable notification. Defaults to "view". Note that Apple no longer shows this in iOS 10 +
• alertTitle : The text displayed as the title of the notification alert.
• soundName : The sound played when the notification is fired (optional).

scheduleLocalNotification()

PushNotificationIOS.scheduleLocalNotification(details);

Deprecated - use addNotificationRequest instead. Schedules the localNotification for future presentation.

Parameters:

details is an object containing:

• fireDate : The date and time when the system should deliver the notification.
• alertTitle : The text displayed as the title of the notification alert.
• alertBody : The message displayed in the notification alert.
• alertAction : The "action" displayed beneath an actionable notification. Defaults to "view". Note that Apple no longer shows this in iOS 10 +
• soundName : The sound played when the notification is fired (optional).
• isSilent : If true, the notification will appear without sound (optional).
• category : The category of this notification, required for actionable notifications (optional).
• userInfo : An object containing additional notification data (optional).
  • image : It's useful if you need to diplay rich notification (optional).
• applicationIconBadgeNumber The number to display as the app's icon badge. Setting the number to 0 removes the icon badge (optional).
• repeatInterval : The interval to repeat as a string. Possible values: minute, hour, day, week, month, year (optional).

addNotificationRequest()

PushNotificationIOS.addNotificationRequest(request);

Sends notificationRequest to notification center at specified firedate. Fires immediately if firedate is not set.

Parameters:

request is an object containing:

• id: Identifier of the notification. Required in order to be able to retrieve specific notification. (required)
• title: A short description of the reason for the alert.
• subtitle: A secondary description of the reason for the alert.
• body : The message displayed in the notification alert.
• badge The number to display as the app's icon badge. Setting the number to 0 removes the icon badge.
• fireDate : The date and time when the system should deliver the notification.
• repeats : Sets notification to repeat. Must be used with fireDate and repeatsComponent.
• repeatsComponent: An object indicating which parts of fireDate should be repeated.
• sound : The sound played when the notification is fired.
• category : The category of this notification, required for actionable notifications.
• isSilent : If true, the notification will appear without sound.
• isCritical : If true, the notification sound be played even when the device is locked, muted, or has Do Not Disturb enabled.
• criticalSoundVolume : A number between 0 and 1 for volume of critical notification. Default volume will be used if not specified.
• userInfo : An object containing additional notification data.

request.repeatsComponent is an object containing (each field is optionnal):

• year: Will repeat every selected year in your fireDate.
• month: Will repeat every selected month in your fireDate.
• day: Will repeat every selected day in your fireDate.
• dayOfWeek: Will repeat every selected day of the week in your fireDate.
• hour: Will repeat every selected hour in your fireDate.
• minute: Will repeat every selected minute in your fireDate.
• second: Will repeat every selected second in your fireDate.

For example, let’s say you want to have a notification repeating every day at 23:54, starting tomorrow, you will use something like this:

const getCorrectDate = () => {
  const date = new Date();
  date.setDate(date.getDate() + 1);
  date.setHours(23);
  date.setMinutes(54);
  return date;
};

PushNotificationIOS.addNotificationRequest({
  fireDate: getCorrectDate(),
  repeats: true,
  repeatsComponent: {
    hour: true,
    minute: true,
  },
});

If you want to repeat every time the clock reach 54 minutes (like 00:54, 01:54, and so on), just switch hour to false. Every field is used to indicate at what time the notification should be repeated, exactly like you could do on iOS.

setNotificationCategories()

PushNotificationIOS.setNotificationCategories(categories);

Sets category for the notification center. Allows you to add specific actions for notification with specific category.

Parameters:

category is an object containing:

• id: Identifier of the notification category. Notification with this category will have the specified actions. (required)
• actions: An array of notification actions to be attached to the notification of category id.

action is an object containing:

• id: Identifier of Action. This value will be returned as actionIdentifier when notification is received.
• title: Text to be shown on notification action button.
• options: Options for notification action.
  • foreground: If true, action will be displayed on notification.
  • destructive: If true, action will be displayed as destructive notification.
  • authenticationRequired: If true, action will only be displayed for authenticated user.
• textInput: Option for textInput action. If textInput prop exists, then user action will automatically become a text input action. The text user inputs will be in the userText field of the received notification.
  • buttonTitle: Text to be shown on button when user finishes text input. Default is "Send" or its equivalent word in user's language setting.
  • placeholder: Placeholder for text input for text input action.

Sets the badge number for the app icon on the home screen

Parameters:

getApplicationIconBadgeNumber()

PushNotificationIOS.getApplicationIconBadgeNumber(callback);

Gets the current badge number for the app icon on the home screen

Parameters:

cancelLocalNotifications()

PushNotificationIOS.cancelLocalNotifications(userInfo);

Cancel local notifications.

Optionally restricts the set of canceled notifications to those notifications whose userInfo fields match the corresponding fields in the userInfo argument.

Parameters:

getScheduledLocalNotifications()

PushNotificationIOS.getScheduledLocalNotifications(callback);

Gets the local notifications that are currently scheduled.

Parameters:

addEventListener()

PushNotificationIOS.addEventListener(type, handler);

Attaches a listener to remote or local notification events while the app is running in the foreground or the background.

Parameters:

Valid events are:

• notification : Fired when a remote notification is received. The handler will be invoked with an instance of PushNotificationIOS.
• localNotification : Fired when a local notification is received. The handler will be invoked with an instance of PushNotificationIOS.
• 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()

PushNotificationIOS.removeEventListener(type);

Removes the event listener. Do this in componentWillUnmount to prevent memory leaks

Parameters:

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
• critical

critical requires special entitlement that could be requested here: https://developer.apple.com/contact/request/notifications-critical-alerts-entitlement/

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:

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:

callback will be invoked with a permissions object:

• alert :boolean
• badge :boolean
• sound :boolean
• critical :boolean
• lockScreen :boolean
• notificationCenter :boolean

• authorizationStatus :AuthorizationStatus

  For a list of possible values of authorizationStatus, see PushNotificationIOS.AuthorizationStatus. For their meanings, refer to https://developer.apple.com/documentation/usernotifications/unauthorizationstatus

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.
