How do I send push notifications to my iOS app? I need to send small messages even when the application is in the background or not running.Is there a simple tutorial. I searched a lot and only found third party solutions. Is there a direct way to access APNs, and if not which third party should I go for.
To send remote notifications, you need your own server that is authorized (you can grab a remote notification certificate from your developer account from developer.apple.com). Then you just follow Apple's API to send a notification to a specific device.
I followed a Ray Wenderlich guide a while back and found it useful.
However, you might not want to set up your own server and stuff. This is where third-party solutions come in. I've worked with Parse's push notification system and found that it is pretty easy to set up.

I have written a number of enterprise iOS apps for our company, all of which have been using the Apple Push Notification function.
I've also written the server-side code for sending the notifications without using a third-party API. It all works great.
Now, Apple is deprecating the old method for sending notifications and moving to an HTTP/2-based system.
I am trying to understand how the HTTP/2 protocol fits in with server-side code in issuing push notifications.
Isn't HTTP/2 just a standard for browsers to follow?
I've studied as much as I can of the Apple documentation for this, and it's no more clear to me now than it was before.
Please pardon my ignorance on this, but even getting the old system to work was an enormous accomplishment for me.
I wish I didn't have to change it.
I'm implementing an iOS application to manage my self-hosted website. My app make use of the many features already built for WordPress-iOS app, but it has differences and extra features.
One of the problem I'm currently having is that push notification was not sent from Jetpack (WordPress.com server) to Apple's APNs, because I'm not getting any notification on my device. I have already registered successfully my device token with Jetpack during app launch.
My problem could be the certificate key (.pem) file not getting uploaded to Wordpress.com (which I do not have access). Is this the reason why I'm not receiving any push notification to my iphone?
Additionally, I'm not getting any result on the NotificationsViewController. I do not have Simperium account setup yet. Could that be my problem for getting no results in NotificationsViewController?
Many thanks.
Sorry about the delay!. For the time being, i'm afraid that WordPress iOS doesn't support 3rd party apps integrations with its Notifications stack.
Meaning that if you'd like to handle Push Notifications support, you'd need to implement a WordPress.org plugin to handle the APN message delivery.
As per the Simperium side, there is no 3rd party app support -at least for now!- due to security restrictions.
If there's anything we could help you with, you may find us on the WordPress Slack (#mobile channel!).
Best,
Jorge
I am implementing the push notification in iOS for sending offers and deals. Right now I am working in the development environment. I see that some of the devices are not being notified. Could anybody explain possible causes? I have also read that if a push is sent to same device multiple times then APPLE disables them for that particular device? Could some one verify this or provide any documentation where I can find the issue. Any feedback would be appreciated.
Not directly answering your question, but what you asked about in the comments and an alternative. You could use a push-notification service such as Parse.
They allow you to send Push Notifications to Web, iOS and Android, also offer data storage and backend infrastructure. The best thing about Parse is that they're free. Unless you have one million unique recipients, which is rather hard to accomplish. Parsee allows you tons end Push Notifications in multiple ways, some including automatic messages based on their tables or other events. You can program those in their cloud code. You can do so using their REST API or their Java Script API if you have a website. You could also send from the Push window on their website.
Setting up is fairly easy. I'll give you the most important links below.

Hope that helps, Julian
If you are dependent on APNS then there is no guarantee provided regarding the delivery of the push notification. And regarding sending multiple notifications. Like if you send notification every min then many may not deliver. Else it will. This service is free and many including myself using it on a regular basis. It has been delivered regularly even though apple will not provide any guarantee. i'm using a php script on server side to send push notification. Refer the below link if you want to know how to send a push notification using php.

Amazon Web Services have an SDK for iOS which supports the Amazon Simple Notification Service (SNS).
Does this mean it would be possible to use SNS to send push notifications to a running iOS app? So for example you could make an real-time instant messaging app.
Is this right, or have I misunderstood what SNS does? It just seems to me that you would need to open a connection/socket in order to recieve push notifications from your server. How does the SDK actually work?
Update:
I've since asked this question on the AWS Mobile Development Forum: https://forums.aws.amazon.com/thread.jspa?threadID=81089&tstart=0
Apparently there is an article coming out (probably here: http://aws.amazon.com/articles/SDKs/iOS) shortly to explain everything.
Update 2
The article: http://aws.amazon.com/articles/9156883257507082
According to Apple documentation "Local notifications and push notifications are ways for an application that isn’t running in the foreground to let its users know it has information for them.".
So, technically speaking, any data, including notifications, received when the application is running in the foreground are not "Push Notifications" and can't be a reason for rejecting the application. They're simply data being consumed that way or the other by the application.
In this specific case you are not asking about Push Notifications per Apple's documentation, rather about a technology used to deliver data to the application when the application is running and user is interacting with it. It happens that the name Amazon SNS is similar to Push Notification.
In any case Apple wouldn't be able to see what is the technology behind delivering data to your application, whether it is Amazon SNS or anything else. All they can see is that the application may have some additional ports open when it's running, and that of course would be absolutely legal. In fact, many applications communicate with their back-end servers using sockets (not HTTP requests), and that is the same technology as used by Apple to deliver their Push Notifications.
According to the Amazon documentation, they in turn uses the APNS method and provide a much simpler frontend for Apple, Android and Kindle. A realtime instant messaging app could be considered as workable since by using the Amazon SNS platform, you could even consider the application to be available for all.
I mean by utilizing the Amazon SNS, the communication could be done between iOS and Android devices and to kindle also provided the applications are written accordingly. Though the Amazon documents do not provide a comprehensive example, there are bits and pieces. Also there is an upcoming event on the Aug 29 which could be seen from the Amazon SNS page.
I have registered with RIM for the push notification evaluation. But i cant find good sources for implementing push notifications. There are some samples in the sdk but i couldnt find out a way to implement them. So, i am looking for a good tutorial where i could find step by step implementation of push notification services...
RIM's samples for the server side involve setting up a web application container (e.g. Tomcat), setting up a backend database, and then building their Spring-based application. This sample web app handles things like device registration, content subscription, etc. and features a portal to manage everything.
The bare minimum that is required, though, is to send a WAP Push message which is just an HTTP POST to their Push Service servers. Here is a thread from the BlackBerry Support Forums that describes how to use their low-level PAP API to construct this message. Pay attention in particular to the messages by the user mdicesare.
There's also another SO question that has some tips.
