I don’t know if it’s documented anywhere, but you can discover what it is by writing a tiny app that adds an observer for all distributed notifications of any time and logs them. or to send out a text/email/tweet when certain notifications are posted, etc. I would think this would be Generally Useful. Wish there were a way… It could be useful. But it would be a very different facility, since the data posted in the notification would need to be machine-readable not human-readable — instead of a localized string you’d want something like an NSDictionary with well-defined keys. (The types of notifications sent out would likely be different too. For example, there’s no point displaying a visible notification when Mail sends a message, but an internal notification would be useful.) Anyway, this facility already exists — it’s NSDistributedNotification. What you’re asking for is basically for more apps to support posting them, which isn’t a technical issue so much as one of evangelism. —Jens ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Receiving system notifications in 10.8
How does one receive notifications from 10.8's new system-wide Notification Center? Is there a framework that allows a Cocoa program to receive system notifications, i.e., the ones that show automatically in the upper right hand of the screen? - Carl ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

No, it’s the other way around — Notification Center is for apps to _send_ notifications to, not receive them. The notifications are purely for the user to see. There are several existing mechanisms like NSDistributedNotification, NSWorkspace and kqueues for getting programmatic notifications of things outside your process. Is there something specific you want to be notified of? —Jens ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
