Can anyone recommend a good starting place for me? I have developed in C#, and understand programming. I'm looking for some specifics for Cocoa and in a larger sense getting into C++ in general. My primary goal is to be able to write extensions and functionality for a program we are getting at my work. It's in C++, so I need to get started. I figured while I'm doing it, I might as well delve into Cocoa as well.
