Write Truly Great iOS and OS X Code with Objective-C 2.0! Effective Objective-C 2.0 will help you harness all of Objective-C’s expressive power to write OS X or iOS code that works superbly well in production environments. Using the concise, scenario-driven style pioneered in Scott Meyers’ best-selling Effective C++, Matt Galloway brings together 52 Objective-C best practices, tips, shortcuts, and realistic code examples that are available nowhere else. Through real-world examples, Galloway uncovers little-known Objective-C quirks, pitfalls, and intricacies that powerfully impact code behavior and performance. You’ll learn how to choose the most efficient and effective way to accomplish key tasks when multiple options exist, and how to write code that’s easier to understand, maintain, and improve. Galloway goes far beyond the core language, helping you integrate and leverage key Foundation framework classes and modern system libraries, such as Grand Central Dispatch. Coverage includes
The handbook of the anal-retentive iOS developer. Objective-C is a complex, mutating monster with a few gray areas (use self.property inside the implementation to access one's properties or access the ivar via _property). I find myself, even while doing full time development, having to occasionally revisit the fundamentals every so often and this (as well as Advanced iOS 6) is a decent place to go for that.
Effective ObjC 2.0 is a well-written book, with plenty of guidelines to help the novice to intermediate ObjC programmer understand the language and its idioms.
I don't think ObjC itself is anywhere near as complicated as Java or C++, where the equivalent books have value even to advanced programmers. This is definitely a "while you're discovering" book, whereas Bloch or Myers can be read at any career stage.
Pretty solid advice. Some of it is a little bit out of date, and often I felt the book was targeted to a more junior developer than myself, but there is some really good low-level information about the Objective-C runtime tucked in here as well.
If you were a fan of Scott Meyer's "Effective C++" series (Scott was a consulting editor for this book) you will love EoC 2.0. If you've been using Objective-C for some time there isn't much earth shattering here but Matt cleanly solidifies many of the concepts that are a bit perplexing for people new to the language. If nothing else it is an awesome refresher.
