What approach to take to communicate with objects

A while ago, I got a question : “There are a few conflicting features in Objective-C/Cocoa to accomplish same goals. What to choose?”

What are they? KVO, Notification, delegation, signaling, conditional lock and so on. You can tell other objects that something happened with those mechanisms.

My choice was to follow existing Cocoa objects’ choice. If they use Notification for certain things and those are similar to what I’m going to implement, I use Notification. If they use delegation, I use delegation, and so on.

Here, again at M-Cubed blog, things are nicely classified and summarized.
The Rules of Communication

See if it is reasonable to you. :)
