we are currently developing iOS applications for different clients.
We have one template application and different derived applications (slightly different layout, but the functionality is nearly the same).
We've chosen to host our backend on heroku and use the PubNub-Addon (with pub-and sub to different channels) to handle push-Notifications.
This works just fine for one application. But if we have multiple applications we need to create one pub nub "application" for each iOS application, because we need to upload the PEM-File (APNS certificate) of the iOS app to the PubNub application which is quite cumbersome.
Is there a possibility that multiple iOS app use the same PEM-File (APNS certificate)? So that we can use one PubNub Application for all the different iOS apps?
Do you have any other suggestions how this problem can be solved?
Thanks in advance!
