This question already has an answer here:
I am pretty new to IOS development and honestly don't know much about certificates, except for the part that they are needed for the application to be posted on Apple store.
My company has few apps on Apple Store, and I got an email saying, "Your Apple Push Notification Service Certificate will expire in 30 days.", for one of the applications.
Now, I am not sure how to renew this certificate.
Here is what I did...
- I logged in to developer.apple.com
- Went to Certificates, Identifiers and Profiles
- Located the application that I got the message for
And Now, I am not sure what to do..
Please see the screenshot below, to see where I ended up..
And from here.. What do I do?
The certificate didn't expire yet, so can I renew it right now? or should I wait for it to expire? If i can do it right now, what do I do? Click on Create Certificate and create a new one? How do I do it?
Just generate a new certificate and replace the old one.
As a side note: when your existing APNS certificate expired, if your server still uses it - existing iOS applications will not be able to receive any notifications from your server. But as soon as you regenerate certificate and update your server to use it - everything will be normal again without any changes to already installed apps.
