Is Objective-C remote-message feature deprecated?

I discovered there is some kind of remote-messaging feature were in Objective-C language. But it is no longer documented. Is开发者_运维问答 it deprecated? What's happening in the feature?

You mean these:

Distributed Objects

Certainly not deprecated as far as I know. More usurped by other mechanisms.

You'll be happier implementing remote messaging with something else. Distributed Objects is still available in the Cocoa framework, but it can be difficult to work with; eg lack of documentation and examples, and lots of gotchas.

ZeroMQ is third party technology for doing remote messaging. BLIP is yet another. There are Objective-C APIs for both.

You could also roll your own thing using JSON and NSURLConnection or embedded HTTP servers.
