Notification Service Extension

Since the release of iOS 10, apps can manage rich push notifications, that is, with images, gif, video, buttons, etc.

In order to use these features, your app needs to implement the Notification Service Extension.

    1. Add a new Notification Service Extension to your project (Xcode: File> New> Target).
    1. Add the extension target in your application.
    1. Once created, you have to look at two points in the NSE target:
      • The Bundle identifier has to be the same as that of the app plus the Display name of the NSE.
      • In the deployment info field, you must indicate the minimum iOS system that you want to impact, so we recommend that it be the same as the one you have planned in the app.

  • You have to be careful at this point because Xcode when creating the target, configures the deployment info in the latest iOS system available. If you do not put it right, on devices below the indicated target it will not show rich notifications.
  • Add the following pod on the app podfile:
target '<YourTargetNotificationExtension>' do
    pod 'indigitall-ios'  

*4. The file NotificationService will have been created within this target. Overwrite all content with the following code:

import Indigitall
class NotificationService: UNNotificationServiceExtension {

    var contentHandler: ((UNNotificationContent) -> Void)?
    var bestAttemptContent: UNMutableNotificationContent?
    var request: UNNotificationRequest?

    override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
        self.contentHandler = contentHandler
        self.request = request
        self.bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)

        Indigitall.didReceive(self.request!, withContentHandler: self.contentHandler!)

    override func serviceExtensionTimeWillExpire() {
        if let contentHandler = contentHandler, let bestAttemptContent = bestAttemptContent {
            Indigitall.serviceExtensionTimeWillExpire(bestAttemptContent, withContentHandler: contentHandler)

#import <UserNotifications/UserNotifications.h>
#import <Indigitall/Indigitall.h>

@interface NotificationService : UNNotificationServiceExtension

@interface NotificationService ()

@property (nonatomic, strong) void (^contentHandler)(UNNotificationContent *contentToDeliver);
@property (nonatomic, strong) UNMutableNotificationContent *bestAttemptContent;
@property (nonatomic, strong) UNNotificationRequest *request;


@implementation NotificationService

- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {
    self.contentHandler = contentHandler;
    self.bestAttemptContent = [request.content mutableCopy];
    self.request = request;

    [Indigitall didReceiveNotificationRequest:self.request withContentHandler:self.contentHandler];


- (void)serviceExtensionTimeWillExpire {
    if (self.contentHandler != nil && self.bestAttemptContent != nil){
        [Indigitall serviceExtensionTimeWillExpire:self.bestAttemptContent withContentHandler:self.contentHandler];


Implementation in AppDelegate

You can see it in our video tutorial or read the instructions below:

Modify the AppDelegate file to import the SDK and override the following methods:

import Indigitall
import indigitall_flutter_plugin

@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
//Notification delegate
    if #available(iOS 10.0, *) {
        UNUserNotificationCenter.current().delegate = self;
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

override func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

override func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    Indigitall.handle(with: response)

override func application(_ application: UIApplication, performFetchWithCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    Indigitall.performFetch(completionHandler: completionHandler)
#import <Indigitall/Indigitall.h>

- (void) application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{
    [Indigitall setDeviceToken:deviceToken];
 [IndigitallFlutterPlugin sendToken:deviceToken]

- (void) didFinishLaunchingWithOptions{
  UNUserNotificationCenter.currentNotificationCenter.delegate = self;
- (void) userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler API_AVAILABLE(ios(10.0)){
    completionHandler([Indigitall willPresentNotification]);

- (void) userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)(void))completionHandler{
    [Indigitall handleWithResponse:response];
  [IndigitallFlutterPlugin handleTapNotification:response]

//Setup Perform Fetch in background
- (void) application:(UIApplication *)application performFetchWithCompletionHandler:(nonnull void (^)(UIBackgroundFetchResult))completionHandler{
    [Indigitall performFetchWithCompletionHandler:completionHandler];

Activate the capabilities

  • Push Notifications in Background Modes
  • Location updates
  • Background Fetch
  • Remote notifications

Time Sensitive Entitlement

If you want to send notifications that can skip the scheduled summary of the user (from iOS 15), you must add the following field in the application entitlement:
