Is there anyone out there who knows if it's possible to 开发者_如何学Cuse 1 production SSL push notification certificate for multiple apps?

No, you need one per app-id.

No, Each App ID is required to have its own client SSL certificate.
For more information Check Apple Guide

The client SSL certificate that is generated is a universal certificate that allows your app to connect to both the development and production environments.

Not use as a wildcard AppId because...
You can create only one explicit App ID that matches your bundle ID. Therefore, if Xcode created an explicit App ID for you—for example, when you added another capability that requires an explicit App ID—you should use it; otherwise, you create an explicit App ID that matches your bundle ID. You then generate and download a corresponding client SSL certificate—this step fully enables push notifications—and refresh provisioning profiles in Xcode. Later, you install the client SSL certificate and key on your server.
