Apple
Push Notification Service (APNs for short), launched together with
iOS 3.0 on June 17, 2009, is the core of the push notifications
element. It is highly resourceful means for distributing information
to iOS and OS X devices. Every device sets up a recognized and
encrypted IP connection with the service and takes delivery of
notifications over this continual connection. If a notification for
an application reaches when that application is not running, the
device alerts the user that the application has data, which can be
reviewed.
Mobile
app developers create the notifications in their
server software. The function of the provider is to watch for the
incoming data for the applications installed by their customers.
When
it comes, the provider connects with APNs through a persistent and
secure channel while monitoring incoming data intended for their
client applications. When new data for an application arrives, the
provider prepares and flings a notification through the channel to
APNs. Subsequently the APNs push the notification to the intended
device. APN stores and sends the notifications may be in the forms of
badges, sounds or custom text alerts.
To
iphone
app developer, it is easy to get your application
receive notifications. But sending messages need a little more
efforts and planning. Code snippets and expert instructions for this
feat are separate. Native
iPhone application developers will be well-experienced
in configuring Cron Job, incorporating APNs to Apple Delegate files.
They can also implement APN service with Play framework.
