Objective-C Programming

这本书最大的特点，是它不把自己当成一本速成手册，而是认真地把读者当成一个'从使用软件的人'转变为'编写软件的人'的普通人。它从C语言讲起，循序渐进地引入Objective-C，甚至愿意花篇幅解释'函数'是什么，这正是它区别于Apple官方文档的关键——官方文档简洁清晰，却假设你已经懂编程，而这本书假设你什么都不懂。多位读者的反馈印证了这一点：有编程基础的人可以直接跳过前面，而没有经验的新手却能在这里找到台阶。它基于Big Nerd Ranch的训练营，章节短小、节奏轻快，适合从头系统学习。不过也要提醒：它'点到即止'，KVC、Block等概念只是领你进门，真正的深入还需回到官方文档与实践中去。
