Primary Objective

摘要

Well that covers the basics of Objective-C. This is probably our most difficult topic so far, due mainly to the strange syntax of Objective-C method calling. I suggest re-reading this column over and over again. In fact, you should put a copy underneath your pillow at night. Well, okay, that may be pushing it. But hopefully by having a side-by-side comparison of C code and Objective-C code, you will find the transition to Objective-C a bit easier.
