How should we use an external push provider and Insider integration NotificationService together?

When integrating an external push provider along with Insider, you might duplicate the NotificationService extension. You can create a separate NotificationService extension to handle push notifications.

If you have two NotificationService extensions, they may conflict inside the application. Instead, use a single NotificationService extension and handle received push notifications based on their source. The example below handles the NotificationService for both Insider One and external push providers.

@interface NotificationService ()
    @property (nonatomic, strong) void (^contentHandler)(UNNotificationContent *contentToDeliver);
    @property (nonatomic, strong) UNMutableNotificationContent *bestAttemptContent;
    @property (nonatomic, strong) UNNotificationRequest *receivedRequest;
    @property (nonatomic, strong) NSString *source;
    @end
    // DO NOT FORGET to change this to your app group
    static NSString *APP_GROUP = @"group.com.useinsider.iGurmeV3";
    @implementation NotificationService
    - (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {
        self.receivedRequest = request;
        self.contentHandler = contentHandler;
        self.bestAttemptContent = [request.content mutableCopy];
        NSDictionary *notificationData = request.content.userInfo;
        self.source = [notificationData objectForKey:@"source"];
        // YOU CAN CUSTOMIZE THESE
        NSString *nextButtonText = @">>";
        NSString *goToAppText = @"Launch App";
        if ([self.source  isEqual: @"Insider"]) {
        [InsiderPushNotification showInsiderRichPush:request appGroup:APP_GROUP nextButtonText:nextButtonText goToAppText:goToAppText  success:^(UNNotificationAttachment *attachment) {
            self->_bestAttemptContent.attachments = [self->_bestAttemptContent.attachments arrayByAddingObject:attachment];
            self.contentHandler(self.bestAttemptContent);
        }];
        return;
        }
        //one signal
        [OneSignal didReceiveNotificationExtensionRequest:self.receivedRequest withMutableNotificationContent:self.bestAttemptContent];
        self.contentHandler(self.bestAttemptContent);
    }
    - (void)serviceExtensionTimeWillExpire {
    if ([self.source  isEqual: @"Insider"]) {
        self.contentHandler(self.bestAttemptContent);
        return;
    }
    // one signal
    [OneSignal serviceExtensionTimeWillExpireRequest:self.receivedRequest withMutableNotificationContent:self.bestAttemptContent];
    self.contentHandler(self.bestAttemptContent);
    }
    @end
