Learning Cocoa was the first tutorial book on Apple's Cocoa frameworks to become available (May, 2001). The book is not very well-written or comprehensive, but it's mostly accurate and serves as a reasonable jumping-off point for programmers who, like me, are new to Cocoa. As I was working through the book's tutorials, I made a number of changes to extend and rewrite the code - a great way to explore Cocoa. I realize the code could be a lot better in places: the blame is partially Apple's, partially mine as a beginner. Given the current lack of good documentation on Cocoa, having this working code would have been a help to me, and I hope it can be of help to others. If you find any outright bugs, please let me know
so I can fix them.
