In this blog, i want to explain you how to make a webservice for an apple push notifcation. first i'll tell you what is Push Notification.
Apple Push Notification service (APNs for short) is the centerpiece of the push notifications feature. It is a robust and highly efficient service for propagating information to iOS and OS X devices. Each device establishes an accredited and encrypted IP connection with the service and receives notifications over this persistent connection. If a notification for an application arrives when that application is not running, the device alerts the user that the application has data waiting for it.
The various parts or the steps of the push notifications.
The Notification Payload
Each push notification includes a payload. The payload contains information about how the system should alert the user as well as any custom data you provide. The maximum size allowed for a notification payload is 256 bytes; Apple Push Notification Service refuses any notification that exceeds this limit.
For each notification, compose a JSON dictionary object (as defined by RFC 4627). This dictionary must contain another dictionary identified by the key aps. The aps dictionary contains one or more properties that specify the following actions:
- An alert message to display to the user
- A number to badge the application icon with
- A sound to play
