[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(NoteCallBack:) name:@"news" object:NULL]; In two threads (in one application) do I need to use the distibuted center?

From the documentation: . Just to be pedantic, it's not object:NULL but object:nil.

Thanks for the help on CFSocket. Finally I left my code as it is - using socket. . It's definitely not a good idea to use the NSNotificationCenter architecture to communicate between 2 threads: "In a multithreaded application, notifications are always delivered in the thread in which the notification was posted, which may not be the same thread in which an observer registered itself." To communicate between 2 threads, you can use Message Port for instance, they work reliably. This email sent to site_archiver@lists.apple.com
