Create/update your Push (APNS) Certificate and P12

This document will show you how to create/update the certificate for an iOS app to be uploaded in Urban Airship Project once done.

To update the certificate and make push notifications work on iOS we need to upload the apns.p12 certificate to the app in Airship. 

Airship sends a payload of the message (characters and sound) and the certificate to Apple and that sends the push to devices.

 Prerequisites:

1. Access to the client's developer account (developer.apple.com...)
2. Mac computer with KeyChain Access

Steps to follow:

5. Select the App ID, taken from the Bundle ID and click on Continue.
   
   
   
   
6. Create a CSR file - Open the Keychain Access app in your Mac, click on Keychain Access on the top left in your Mac and then on Certificate Assistant > Request a Certificate From a Certificate Authority.

   - User Email Address: the same username you used to log into developer.apple.com
