I would like to send a silent notification to my app users, to refresh the content.
I have read various articles on sending silent notification to opted out users. But, how do we do it? Most opted out users don't have device push tokens. How do you ping a device to send the silent push payload?
We currently use push tokens for opted in users to send a remote notification. But if iOS 8 and beyond allows to send silent notification to all the app users even if they are opted out, how do I send them without a token?
There are no possibility to send remote notifications to devices that are not registered with a device token. Also you can not send any notification if user doesnt allow the app to receive remote notifications.

I want to know if I can receive payload from FCM in my iOS app, even if the user doesn't allow notifications for my app. I don't want to show them as notifications, i just want to handle their payload.
Does background messaging work without permission?
Does foreground messaging work without permission?
The Firebase Cloud Messaging APNs interface uses the Apple Push Notification service (APNs) to send messages up to 4KB in size to your iOS app, including when it is in the background.
Notification permission is required for both background and foreground work (even if your push notification is a silent one i.e no notification needs to be displayed)
You still need the user to allow the notifications, later on, you can implement the handling as silent or not, up to you.
In order to receive the payload you need, it must come from a push notification.
I am sending bulk push notifications to IOS users through APNS , and want to check the response of all the users , to check if any of them has uninstalled the app or not.
You can't be sure with Push Notifications about anything, Apple never guaranty the delivery of the Notification.
Your notification may never be delivered simply because when you send it he is in high mountain hiking with no data cover, or his phone is turned of, or he has killed your app from task manager (unless your send a VoIP notification), ecc.
Is there any way to handle remote notification payloads before they’re delivered and display in notification centre?
With push notifications of default type there is no way to filter out notifications if the app is not in foreground.
The possible solution to this is to use VoIP push notifications in conjunction with PushKit.
VoIP pushes are always waking up the application, however they are not presented to the user and don't modify app badge value, so it's up to the developer to show a local notification upon the received VoIP push and to deal with app badge.
There is a technique with additional silent push that for example Facebook is using, to delete notification on iOS device when the message has been read on desktop web site. It's described here: https://www.pushwoosh.com/docs/deletable-ios-push
I have an existing app that receives push notifications. I've been requested to implement a feature where the user must acknowledge the push notification. If the user does not acknowledge the notification, then they will be alerted again after a set time, until they finally do acknowledge it.
So far, the only solution I've come up with is:
We send a notification from our server to APNS. When the user opens the app after receiving a notification, the app will then send an acknowledgement back to the server. If the server does not receive an acknowledgement from the device within X minutes, it will automatically send another notification.
Is there a better way of implementing this kind of feature, where I'm not relying on sending acknowledgments back to the server?
Create Accept/Reject actions for push notification and save that info on server, so that we can differentiate the accepted ones and others
I created an app which receives push notifications from my server. At the same time, if some other app is sending push notifications (for e.g., whatsaap, twitter), the notification is getting displayed when I'm using my app. I want to hide all other app's push notifications except my app's push notifications. Can this be done in iOS? I want my app to receive push notifications only from my server but not from the other apps.
Thanks in advance.
Try to think like your customer. Would they like to receive the push notifications of the other apps (whatsapp, twitter, the notification that a very important email just arrived)? Of course they would. Your App is one of many and most probably not the most important one they own.
Let me provide some background first.
Your app can only receive notifications from your service/server.
The user might have apps that are receiving notifications from the respective service/server.
e.g. if the user has FB app, then it would be receiving notification from FB servers.
In the end, you are only responsible for managing your service/server.
There is no way for you to block notifications that are received from other services from your app.
Hope this helps.
