Push Notification for Existing iOS App

I am new to PushNotifications . I ran into a problem while providing a push notification for existing AppID .

I have long created a certificate, a Provisioning profile for an application. At that time, I did not enable push notifications. To enable push notifications, I registered with the Apple Developer Account , and in AppIds I clicked the check button to enable push notifications. Then the setting buttons are turned on. If I click on the setting in the Production section, he will ask me to create a certificate. But I already have a Certificate. I cannot delete an existing certificate because most of my applications use an existing certificate. So please help me enable push notification.

  • Incase If I delete the certificate, will it affect already installed applications on devices? Please let me know if my question is not clear.

To send push notifications you will need to create an SSL certificate. This is another matter and is not related to the “ordinary” certificates, which you must create and maintain in any case.

You will need to renew the ssl certificate. on an annual basis. This certificate is not even associated with the application. This is necessary on a server that sends push notifications to Apple.

My advice: just follow the instructions and do not be confused with any of the other certificates. And, of course, there is no need to delete the existing application certificate.

First of all, it’s normal to cancel your development or issue certificates and create new ones without affecting your applications currently released in the application store. This can be done at any time.

However, to set up push notifications, you install even more certificates. These certificates are not actually associated with your application, but are intended to be used by your push notification system. You create a certificate for development and a certificate for release.

In the future, if you need to revoke these push certificates, you can do this and create new ones without affecting the application in the store. You will need to upload new push certificates to your push notification system before you can send push notifications to your application in the store, but you do not need to make a new version of the application.
