I have not ever been able to send a push notification and have it be successfully delivered. All devices are registering for push notifications and all seems well but they never get my notification.
The app name, ID, and certificates are all correct.

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.
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.
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
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 .
