Learning Objective-C 2.0: A Hands-on Guide to Objective-C for Mac and iOS Developers (2nd Edition) Book Review

If I had to give this book a one word description, I would say it is 'balanced'. In the beginning of the book the author mentions that he does not want to right one of those books that list a little code and then explains the code, changes the code, explains those changes and so on and so on.

At first he scared me. I have read some insanely wordy programming and engineering books. I have a much harder time getting through those than the type the author described. I was afraid this book would be one of those that I don't get anything out of except war stories from the author's career. That would not be all bad if the stories had anything to do with the book. I am happy to report that is not what happened.

I found the author had just the right amount of discussion around the different language features he was covering. I thought that the offer had a very no nonsense approach to all the topic that he covered.

The book is broken down into four parts. Below I have listed the three different parts, and the chapters that they contain.

Part I: Introduction to Objective-C
Chapter 1. C, the Foundation of Objective-C
Chapter 2. More about C Variables
Chapter 3. An Introduction to Object-Oriented Programming
Chapter 4. Your First Objective-C Program

Part II: Language Basics
Chapter 5. Messaging
Chapter 6. Classes and Objects
Chapter 7. The Class Object
Chapter 8. Frameworks
Chapter 9. Common Foundation Classes
Chapter 10. Control Structures in Objective-C
Chapter 11. Categories, Extensions, and Security
Chapter 12. Properties
Chapter 13. Protocols
Part III: Advanced Concepts Chapter 14. Memory Management Overview
Chapter 15. Reference Counting
Chapter 16. ARC
Chapter 17. Blocks
Chapter 18. A Few More Things

Part IV: Appendices
Appendix A. Reserved Words and Compiler Directives
Appendix B. Toll-Free Bridged Classes
Appendix C. 32- and 64-Bit
Appendix D. The Fragile Base Class Problem
Appendix E. Resources for Objective-C

One thing I really liked about the book was that the author did not use ARC throughout the book. He decided that reference counting is a very important topic to understand. The logic is that you're going to have to work with legacy code that is not going to be using ARC. There's much more legacy code out there then there is new code. He does take the time to explain how ARC works later in the book and the advanced concepts part.

I thought that I would lightly skim the first few chapters that cover the foundation of Objective-C. But as I was skimming, I found the author's writing style very nice to read, and therefore I ended up reading it word for word.

I must admit that I have been using messaging for a while now, but I never really understood messaging within the Objective-C context until I read this author's explanation of it. The author also has excellent coverage of properties and all of the different ways they can be declared.

The chapter on blocks was also very well put together. The author starts out by explaining function pointers and the issues that you can run into using them. He then does a very thorough job of covering blocks.

Every chapter in the book is a gem and overall I found this author's writing style made the book very easy to read. This book will stay by my side. It's not only a good cover to cover read, it is also a very good reference.

I would recommend this book as the place to start for anyone coming from a different find which such as C# or Java, and also as the place to start for anybody looking to get into building applications with Objective-C.

Early in my DevOps Journey, I was introduced to a book of great significance circulating within the Web Operations industry titled The Phoenix Project. (You can read our review of Gene’s book, if interested.) Written as a novel and loosely based on many of the same principles explored in The Goal, this book has been read and referenced by many who have adopted DevOps into their continuous improvement and software delivery processes around the world. As I began planning my travel schedule last...
Skeuomorphism usually means retaining existing design cues in something new that doesn’t actually need them. However, the concept of skeuomorphism can be thought of as relating more broadly to applying existing patterns to new technologies that, in fact, cry out for new approaches. In his session at DevOps Summit, Gordon Haff, Senior Cloud Strategy Marketing and Evangelism Manager at Red Hat, discussed why containers should be paired with new architectural practices such as microservices rathe...
It’s been proven time and time again that in tech, diversity drives greater innovation, better team productivity and greater profits and market share. So what can we do in our DevOps teams to embrace diversity and help transform the culture of development and operations into a true “DevOps” team? In her session at DevOps Summit, Stefana Muller, Director, Product Management – Continuous Delivery at CA Technologies, answered that question citing examples, showing how to create opportunities for ...
Any Ops team trying to support a company in today’s cloud-connected world knows that a new way of thinking is required – one just as dramatic than the shift from Ops to DevOps. The diversity of modern operations requires teams to focus their impact on breadth vs. depth. In his session at DevOps Summit, Adam Serediuk, Director of Operations at xMatters, Inc., will discuss the strategic requirements of evolving from Ops to DevOps, and why modern Operations has begun leveraging the “NoOps” approa...
In today's digital world, change is the one constant. Disruptive innovations like cloud, mobility, social media, and the Internet of Things have reshaped the market and set new standards in customer expectations. To remain competitive, businesses must tap the potential of emerging technologies and markets through the rapid release of new products and services. However, the rigid and siloed structures of traditional IT platforms and processes are slowing them down – resulting in lengthy delivery ...

He will describe a DevOps approach where the applications and systems work together to track usage, model costs in a granular fashion, and make smart decisions at runtime to minimize costs. The trickier parts covered include triggering off the right metrics; balancing resilience and redundancy ...
Docker containerization is increasingly being used in production environments. How can these environments best be monitored? Monitoring Docker containers as if they are lightweight virtual machines (i.e., monitoring the host from within the container), with all the common metrics that can be captured from an operating system, is an insufficient approach. Docker containers can’t be treated as lightweight virtual machines; they must be treated as what they are: isolated processes running on hosts....
Before becoming a developer, I was in the high school band. I played several brass instruments - including French horn and cornet - as well as keyboards in the jazz stage band. A musician and a nerd, what can I say? I even dabbled in writing music for the band. Okay, mostly I wrote arrangements of pop music, so the band could keep the crowd entertained during Friday night football games. What struck me then was that, to write parts for all the instruments - brass, woodwind, percussion, even k...
Whether you like it or not, DevOps is on track for a remarkable alliance with security. The SEC didn’t approve the merger. And your boss hasn’t heard anything about it. Yet, this unruly triumvirate will soon dominate and deliver DevSecOps faster, cheaper, better, and on an unprecedented scale. In his session at DevOps Summit, Frank Bunger, VP of Customer Success at ScriptRock, will discuss how this cathartic moment will propel the DevOps movement from such stuff as dreams are made on to a prac...

What does “big enough” mean? It’s sometimes useful to argue by reductio ad absurdum. Hello, world doesn’t need to be broken down into smaller services. At the other extreme, building a monolithic enterprise resource planning (ERP) system is just asking for trouble: it’s too big, and it needs to be decomposed.
Several years ago, I was a developer in a travel reservation aggregator. Our mission was to pull flight and hotel data from a bunch of cryptic reservation platforms, and provide it to other companies via an API library - for a fee. That was before companies like Expedia standardized such things. We started with simple methods like getFlightLeg() or addPassengerName(), each performing a small, well-understood function. But our customers wanted bigger, more encompassing services that would "do ...
The pricing of tools or licenses for log aggregation can have a significant effect on organizational culture and the collaboration between Dev and Ops teams. Modern tools for log aggregation (of which Logentries is one example) can be hugely enabling for DevOps approaches to building and operating business-critical software systems. However, the pricing of an aggregated logging solution can affect the adoption of modern logging techniques, as well as organizational capabilities and cross-team ...
Culture is the most important ingredient of DevOps. The challenge for most organizations is defining and communicating a vision of beneficial DevOps culture for their organizations, and then facilitating the changes needed to achieve that. Often this comes down to an ability to provide true leadership. As a CIO, are your direct reports IT managers or are they IT leaders? The hard truth is that many IT managers have risen through the ranks based on their technical skills, not their leadership ab...
DevOps has traditionally played important roles in development and IT operations, but the practice is quickly becoming core to other business functions such as customer success, business intelligence, and marketing analytics. Modern marketers today are driven by data and rely on many different analytics tools. They need DevOps engineers in general and server log data specifically to do their jobs well. Here’s why: Server log files contain the only data that is completely full and accurate in th...
Brands are more than the sum of their brand elements – logos, colors, shapes, and the like. Brands are promises. Promises from a company to its customers that its products will deliver the value and experience customers expect. Today, digital is transforming enterprises across numerous industries. As companies become software-driven organizations, their brands transform into digital brands. But if brands are promises, then what do digital brands promise – and how do those promises differ from ...
