I have attempted to read probably close to 100 computer books on all sorts of languages and topics, none of them compare to how well this one is written. I'm currently only 37% through this book, but loving it. I've attempted to learn Objective-C a number of times over the past couple of years, mainly just to know it, but also in hopes of diving into IOS development. I've tried to read other books as well as videos on Lynda.com and pluralsite.com. I'm often left so confused on why I'm typing something and the book/video tells me not to worry about understanding it right now, I'll eventually understand. With this book, when it says not to worry about something for the time being, it ends up covering it as soon as I need to know it and in a way that I can understand.As I've been reading this book, I've felt that I should actually take the time to write a review, but thought I'd wait until I was finished, just in case I actually found a typo in a code sample, I haven't yet. However I'm currently reading chapter 19 that covers properties and felt compelled to write the review right now. In previous books/videos, they've talked about properties, I had no idea what was all going on with them and felt they must not be very important based on the ways they'd been presented. In chapter 18, Aaron teaches you about instance variables, getters and setters. You end up declaring them in the header and implementing them in the .m file and using them in the main() function. He teaches you about recommended naming of these variables and methods and then in chapter 19 shows you that declaring a property takes care of creating instance variables, header declarations and implementations of the getters and setters. I now actually understand what @property does in a header file.This is the first book I've read by Aaron Hillegass and the Big Nerd Ranch, but I plan on reading the rest of them. I can't say enough good stuff about this book and author.
I bought this based on all the great reviews - I expected a GREAT book. And since it was the 2nd, revised edition, any rough spots or areas that needed more explanation from the 1st edition would be taken care of. And since there's a BNR forum dedicated to this book by the book's publisher, surely any errors found in the book would be documented there, as well as anything that changed with the newer version of X-code.But I was pretty disappointed. There are gaps where the book seems to assume you know something it never told you. You log into the forum and there are other users just as confused. But there's no "official" answer from the publisher or the author to settle it. Many of the examples have changed slightly with Xcode 6 - I would have expected there to be a (sticky) errata in the forum updating that, but there's not. There are several knowledgeable forum members who provide a lot of help with most of the issues that arise, but I expected something more official.To be fair, this book has a really big goal - to try to teach Objective C to people that don't even know C. So I knew there would be areas where coverage would be light and I'd need to supplement with other sources (Stack Overflow, wikis, Apple's documentation, etc.). But there are sections that seem to be less clear/more frustrating than they could have been.
I have purchased and studied several other Objective-C books and this one, by Aaron Hillegass and Mikey Ward is the best, by far. Here's my thoughts:1. Comprehensive: dives into and explains many nooks and crannies, not only in Obj-C but also iOS and OS X.2. Very well written, step by step, but with plenty of excellent information about why the code or concept works the way it does.3. The chapters are organized well, and short and sweet, providing a bite-size approach to tacking this huge (and daunting, at times) challenge of learning. It's doable to go through one chapter a day, building knowledge, insight, and confidence.4. The chapters have very good challenge exercises: you should do all of them! Don't undermine your learning by skipping them.5. Last, BNR provides very helpful on-line resources: discussion forum, errata, and other.Now, a couple of weeks ago Apple announced Swift and for a while I wondered if anyone (such as me) would ever want to know or continue studying Objective-C. I believe a deep knowledge and comprehension of Objective-C will remain important for at least a couple of years:1. Swift works hand-in-hand with Obj-C, and while it's different, there are powerful ways to leverage Obj-C frameworks. Since Swift is so new, I imagine that we'll be using Obj-C frameworks for quite a while, as needed.2. Learning the vocabulary of object-oriented programming, particularly as Apple uses it, is very important of course, and while Swift is different, many Swift concept descriptions have references to Obj-C to increase understanding.3. Obj-C programs will be around for years, and so if you want to work in Apple Land, well, they'll be there waiting for maintenance, and enhancement.So long story short: this is an important and useful book. Highly recommended.
I have 2 years computer science background, did some Ruby, PHP, C, Java and web development but still a beginner programmer. Even with my exposure I think that some of the topics that are introduced, introduce too many concepts at once, instead of presenting them one by one, making this book a little hard to read for what is supposed to be a beginners book. I am still half way through and already I have that impression. It should explain every little thing in order. As far as it teaching you what you need to know, I am not sure yet, but judging by what others say hopefully it does. It is also very dry and boring - it can use some fun exercises. I was considering 3 stars but will give 4 based on other people's impressions.
