I am implementing push notification in my app. It was working fine. Right now i am testing this on my development profile. After few times i send push notification to my device, server stops sending any more push notification. I tried searching but can't find anything about the limit. How many times can we send push notification to a particular device token on development as well as distribution profile?
Push notification message size is 256 bytes or below you can send notification number of times .

I'm developing an iOS app and I'm facing this weird bug where the push notifications come in bursts.
Basically, let's say I send 10 push notifications with APN from a server (my logs show that the push notification sends), but I don't receive it until some arbitray time later, when I receive all 10 notifications at once.
I've double-checked my app-side code and have also tried re-generating/re-uploading the p12 certs and after looking around here, I haven't managed to find anything either./
Would anyone be able to shed some light on this? Any help is appreciated!
*UPDATE: my logs show that every time the server sends a push notification, it also sends a 'apple sandbox notification' simultaneously, but I'm notsure what that is
So, I have about 1000 iOS users installed my app.
I tried to send push notification to these users thru my app's backend panel, however, my devices did not receive the push notification. I also asked some users, and some of them said they did receive the push notification and some did not.
I was wondering why not all of the 1000 iOS users receive the push notification successfully.
At first, I thought it has to do with my applications, because my device has the latest update that is yet to release to public. So I went on and delete all the device tokens I got, and register my device again to test the push notification.
This time, my device received the push notification from backend panel successfully. So, I am sure there is nothing wrong with the coding part on receiving push notifications. (I ran multiple test on this and sure that push are send and receive successfully)
It only happens when I tried to send bulk push notifications to iOS users.
so, is sending push notification has a limit? like it only allows to send may be to 100 users?
or may be there are invalid device token so that pushes are stopped before finish sending to all users? but in what situation device token become invalid? will uninstalled user's device token may be a cause?
In our experience notifications have far from a 100% delivery rate, and that's with only between 50 and a 100 installs across iOS. In theory there is no cap set in place.
The only limits I'm aware of is sending an identical notification to the same device multiple times within a short window of time.
We have been using APNS on our app, our users are complained that they are receiving the same push notification twice. Our servers are sending only one push notification payload to Apple, the second push notification reaches to users after one hour of the first push note arrival.
Is any one facing the same issue?
I want to develop an app regarding push notification.
I want to send a push notification to 5 persons who has installed my app and are stored in my directory.
Can I send Push Notification to 5 people using their UDID which I received from each and every person who has installed App. (As UDID is banned)
I want to send them continuously to 5 persons till one does not press OK button on Alert?
Which service should I use for Push Notification?
Is push notification receives on time or it delays?
You cant send the push notification using UDID, you can use the Apple service for sending the push notifications via device-token and pem file which is explained in below link.

Any push notification that isn't delivered immediately was queued for future redelivery because your device was not connected to the service. "Immediately" of course needs to take latency for your connection into account. Outlying cases would be beyond 60 seconds as APNs will time out at that point.
Still you have any query then you can refer the below link http://developer.apple.com/library/ios/#technotes/tn2265/_index.html
For our iOS news apps we send out more than 10000 push notifications to registered devices, but somehow not all devices seem to receive the notification. We have been doing this for years but recently we received user feedback stating they did not receive a push notification while they did register their device to receive them.
Our logs show that these specific devices registered successfully and that there were no errors sending the push notification, but somehow the APNS does not deliver the notification. We have seen that removing the app from the device and reinstalling it sometimes solves the problem but we are still concerned.
We think it must be Apple's service that fails to deliver the push notification sometimes, especially when it comes to sending large amounts of notifications. Any of you experienced this?
The Apple docs says this:
Important: Delivery of notifications is a “best effort”, not
guaranteed.
Have you checked the payload size? As per Apple's documentation, the maximum size allowed for a notification payload is 256 bytes.
