Push Notification for existing appid in iOS

Question

I am new to PushNotifications . I have been facing an issue while enabling the push notification for existing AppID .

Long time ago I had created the Certificate, Provisioning profile for an app . At that time I didn't enabled the push notifications . To enable the push notifications I have logged into the Apple Developer Account and in the AppIds I have clicked the check for enabling the push notification . Then configure buttons have been enabled . If I click on the configure in the Production it is asking me to create the certificate . But I have already had a Certificate . I can't delete existing Certificate because most of my apps using the existing certificate . So please help me to enable the push notification .

1. Incase If I delete the certificate will it effect the already installed apps on the devices ? Please let me know if my question not clear.

Answer 1

First of all its totally ok to revoke your development or release certificates and make new ones without affecting your apps currently released in the app store. This can be done at any time.

However for setting up push notifications you are setting up yet more certificates. These certificates dont actually get bundled with your app but are for use 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 so and create new ones without affecting the app in the store. You will need to upload the new push certificates to your push notification system before you can send push notifications to your app in the store but you wont need to do a new release of the app.
