Overview
For those who are new to APNS, let’s have a brief introduction on how APNS works.

As mentioned in ​Apple’s official documentation​  : 

1. The app registers for push notifications with SSL connect. 
2. Device   receives   the   device   token   which   acts   as   an   address   where   the  notifications will be sent. 
3. Client app uses this device token to send the notifications. 
4. Client app send this device token to your server  
5. When   the   app   wants   to   push   any   message,   the   server   send   a   push   notification   to APNS 
6. And then APNS send the push notification to user’s device.

Usage at Naukri 

Currently, in Naukri, push notifications are used for the following functionalities: 

• Recommended jobs ­ Sending Recommended jobs to the users.
• Update   Profile – keeping   your   profile   updated   helps the   naukri   to   suggest   more   relevant   jobs to their users.   
• What’s   New – Announcing   new   features   and   updates for better experience of users.  
• Apply   History – Showing   apply   history   of   the   user  helps the user to track his actions. 

Handling Badge Number 

Badge is a little red circle in the top right corner of your iOS app, which tells the user that there is some information to be read. But there are some cases in which the badge number displayed over the app is incorrect. This can confuse and frustrate the user. So, to handle such issues Naukri has adopted few solutions.  

• Badge number always come from server in payload. So, in order to ensure that the badge number should be cleared after the notification has been read , the badge counter is first locally updated and then server is notified about the change.
• If a user is logged in from multiple devices then all the devices receive the push notifications. 
• The device id is cleared on the server if user logout to ensure that the next user whosoever will login on the same device doesn’t receive unnecessary notifications
