APRESS 出过一个“Learn 系列”：《Learn C on the Mac》、《Learn Objective-C on the Mac》、《Learn Cocoa on the Mac》，最后还有一本《Beginning iPhone Development: Exploring the iPhone SDK》。另外 Apple 开发者网站上的文档写得也非常棒。
There is a 'Learn Series' from APRESS 'Learn C on the Mac', 'Learn Objective-C on the Mac', 'Learn Cocoa on the Mac', and finally 'Beginning iPhone Development: Exploring the iPhone SDK'. Apple also has very good documentation on their developers site.
……所以我读了 K&R 的第一章并做完了所有习题，然后挑着读了其他几章（我记得是第 2、5 和 6 章）。在那之后，我读了这本书：http://www.apress.com/book/view/1430218150。《Learn Objective-C on the Mac》太赞了——可读性强、幽默风趣、简明扼要且内容全面。它解答了我对 ObjC 遗留的所有疑问，我终于感觉自己真正掌握这门语言了。
…so I read the first chapter of K&R and did all the exercises, then read a few of the other chapters (2, 5, and 6 I believe). After that, I read this book: http://www.apress.com/book/view/1430218150 . "Learn Objective-C on the Mac" has been great - it's readable, good-humored, succinct, and comprehensive. It's answered all the remaining questions I still had about ObjC and I finally feel like I get the language.
……似乎是 Kochan 先生那本 C 语言书（上面提到的）极好的续篇——真希望我当初读的是这本，而不是 Dalrymple/Knaster 写的。总结：没法给出推荐，因为我没完整读完 Mark Dalrymple 和 Scott Knaster 写的《Learn Objective-C on the Mac》——这是《Learn C on the Mac》的续作，但我没那么喜欢——文风有时有点让人摸不着头脑。我还是更喜欢 Dave Mark 写的 C 语言那本。-……
…Seems to be a great continuation from Mr. Kochan's C book (above) - I wish I read this instead of Dalrymple/Knaster's Bottom Line: Can't give a recommendation because I haven't fully read it Learn Objective-C on the Mac, by Mark Dalrymple and Scott Knaster - Continuation from "Learn C on the Mac", but I didn't like it as much - Writing style was a bit confusing at times. I preferred Dave Mark's C book. -…
……工具——包括 Cocoa——都是免费的，所以任何 Mac 程序员都可以拿来用。你所需要的只是一点点编程经验、Objective-C 的基础知识，以及想要钻研并学习新东西的渴望。摘自《Learn Objective-C on the Mac》http://my.safaribooksonline.com/book/programming/objective-c/9781430218159/hello/what_apostrophy_s_coming_up
…tools—including Cocoa—for free, so any Mac programmer can take advantage of them. All you need is a bit of programming experience, basic knowledge of Objective-C, and the desire to dig in and learn stuff.
