Is there some mechanism to determine which clients get which notifications? I have users that belong to groups, and each notification needs to go to a specific group.
After a couple days of getting familiar with iOS notifications (got the basics working), I have not come across much or actually anything on this topic. Is there a good resource somewhere? I have it working with tags on Android, but that doesn't seem to work for iOS; all clients still get all messages.
Also, sounds for notifications, they are mentioned, but... where is some sample code?
