Send and receive messages through NSNotificationCenter in Objective-C?

Question

I am attempting to send and receive messages through NSNotificationCenter in Objective-C. However, I haven\'t been able to find any examples on how to do this.

if you're using NSNotificationCenter for updating your view, don't forget to send it from the main thread by calling dispatch_async:

dispatch_async(dispatch_get_main_queue(),^{
    [[NSNotificationCenter defaultCenter] postNotificationName:@"my_notification" object:nil];
});
