Umm I think the word “push” is the operative term here, the notification service on the phone is always listening via an IP connection it establishes with the APNs, so it only ever does anything when it receives a notification from the service, no “polling” is happening as far as I can tell. F
rom some Apple documentation …. Each device establishes an accredited and encrypted IP connection with the service and receives notifications over this persistent connection. If a notification for an app arrives when that app is not running, the device alerts the user that the app has data waiting for it. https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/ApplePushService.html From: [email protected] [mailto:[email protected]] On Behalf Of Leigh Wanstead Sent: Thursday, 21 May 2015 9:04 a.m. To: NZ Borland Developers Group - Delphi List Subject: Re: [DUG] Parse.com IPhone 3 Good morning Willie, Thanks for the answer. Quote You can register your phone application against a push notification server so that it can receive notifications from that server, these appear on your phone in much the same way as email, What’s-App or Update notifications do. Does that mean the ios app constantly pull from the server to check any new notification just like normal outlook check email server logic?

You can register your phone application against a push notification server so that it can receive notifications from that server, these appear on your phone in much the same way as email, What’s-App or Update notifications do. You use either the Apple Push Notification Service for IOS devices, or for Android devices the Google Cloud Messaging service as the delivery system (don’t know what windows devices do). In my case I’m using PARSE.COM <http://PARSE.COM> as the push notification server, it’s free and Delphi comes with a ready-made client component (I believe there are Delphi tutorials that show how to create your own servers if you want to go that way). I created a “server application” on the parse.com <http://parse.com> website, this is a pretty straight forward and generic process, and from this I get application keys that my phone app will use to subscribe to my PARSE.COM <http://PARSE.COM> server app. I generate notifications for my PARSE server to send out via a website (PHP) – PARSE give you a number of API SDK’s for different programming languages that make this process fairly easy to implement. Each client device that registers against a PARSE.COM <http://PARSE.COM> server application ends up with a unique InstallationID and DeviceToken for that server app. When you want to send out a notification you can use either of these to target individual phones/tablets or you can target groups (PARSE call these channels). Once installed and registered, your phone app doesn’t have to be running for the phone to receive notifications for it, they are received into the device’s notification centre, when you view them and click on one of your phone-apps notifications it will automatically open your app. Having written all of that which probably doesn’t answer your question …. There are pretty good tutorials by Sarina on the Embarcadero site about building a phone app (IOS and Android) for both PARSE and Kinvey, she also takes you through the Notification Server setup. I recommend you go through those you’ll get a better understanding.
