Objective-C Programming: The Big Nerd Ranch Guide (2nd Edition)

This book is the perfect place for an experienced developer to start with iOS programming

This book is the perfect place for an experienced developer to start with iOS programming. I say experienced developer because this book does a great job of showing you the basics of C and the Objective-C language, but if you don't understand the basics of programming, you are probably going to get lost. Maybe not, but I found myself saying, "I am glad I already know what that is" about quite a few topics that were used to explain the subject matter. If you are experienced with C#, C, Java, or C++, you will be fine.

This book does a great job of showing you what you need to know to get started with iOS. When you are done with it you should be able to easily move into learning more by reading more books, like iOS Programming: The Big Nerd Ranch Guide (4th Edition). You will need to learn a lot more to be proficient in Xcode and iOS.

The book is broken down into 5 parts. I have summarized each below:

Getting Started (Chapters 1-2)
This first part explains what you can expect from the book, and what the author's expect of you. It then takes you through the steps of creating your first application with Xcode.

How Programming Works (Chapters 3-12)
In this part you get an overview of C. The authors take you on a tour of some programming concepts using the functionality provide by the C language. Topics they cover include Functions, Variables, Types, if/else, Loops, Numbers, Format Strings, Pointers, the Heap, and Structs.

Objective-C and Foundation (Chapters 13-30)
In these chapters the authors take you on a tour of object oriented concepts and Objective-C. Topics covered include Objects, Messages, Memory, NSArray, NSString, Classes, Inheritance, Instance Variables, Leaks, Collection Classes, Constants, Reading and Writing Files, Callbacks, Protocols, and Property Lists.

Event-Driven Applications (Chapters 31-32)
In this part you write an iOS and a Cocoa application. While building the applications the authors introduce the Model-View-Controller pattern, setting up views, wiring up buttons and table views, loading and saving data, Interface Builder, and they discuss the role the application delegate plays.

Advanced Objective-C (Chapters 33-37)
Here the authors cover init, more about properties, key-value coding and observing, and categories.

Advanced C (Chapters 38-42)
In these final chapters the authors cover C strings, bitwise operators, C arrays, and using the command line and command line arguments.

How are the code samples? Well that will be up to you because the author's policy is this - "Given that the code samples are short. And that they often go through a few revisions. And that if I publish the code some people will read it instead of typing it in. I'm not going to make the code available."

You will need to type the examples if you want to see them in action. That is not such a big deal because the way the authors use the samples throughout the book is add this ABC code, and then in the next example delete ABC code and add XYZ code, and then leave XY, but delete Z and add DEF code. The authors tell you at the beginning of the book you are going to want to read this in front of a Mac. They aren't kidding.

Coming from a long career in C#, and before that C and C++, this was the perfect place for me to start with iOS programming. I have this second edition and the first edition. I never got around to reviewing the first edition, but wanted to make sure I reviewed this one because I feel it is an awesome asset to the experienced programmer looking to get into iOS programming.

The book also makes a good reference. Topics are short and to the point. There isn't any filler in this book, so when you need to look something up you have a nice concise explanation at your fingertips.

All in all, if you are looking to get into iOS, this is a great place to start. If you are an experienced iOS developer, it makes a nice reference for the features only used once in a blue moon.

DevOps Summit 2015 New York, co-located with the 16th International Cloud Expo - to be held June 9-11, 2015, at the Javits Center in New York City, NY - announces that it is now accepting Keynote Proposals. The widespread success of cloud computing is driving the DevOps revolution in enterprise IT. Now as never before, development teams must communicate and collaborate in a dynamic, 24/7/365 environment. There is no time to wait for long development cycles that produce software that is obsolete at launch. DevOps may be disruptive, but it is essential.
“In the past year we've seen a lot of stabilization of WebRTC. You can now use it in production with a far greater degree of certainty. A lot of the real developments in the past year have been in things like the data channel, which will enable a whole new type of application," explained Peter Dunkley, Technical Director at Acision, in this SYS-CON.tv interview at @ThingsExpo, held Nov 4–6, 2014, at the Santa Clara Convention Center in Santa Clara, CA.

The major cloud platforms defy a simple, side-by-side analysis. Each of the major IaaS public-cloud platforms offers their own unique strengths and functionality. Options for on-site private cloud are diverse as well, and must be designed and deployed while taking existing legacy architecture and infrastructure into account. Then the reality is that most enterprises are embarking on a hybrid cloud strategy and programs.

Nigeria has the largest economy in Africa, at more than US$500 billion, and ranks 23rd in the world. A recent re-evaluation of Nigeria's true economic size doubled the previous estimate, and brought it well ahead of South Africa, which is a member (unlike Nigeria) of the G20 club for political as well as economic reasons. Nigeria's economy can be said to be quite diverse from one point of view, but heavily dependent on oil and gas at the same time. Oil and natural gas account for about 15% of Nigera's overall economy, but traditionally represent more than 90% of the country's exports and as...
The Internet of Things is a misnomer. That implies that everything is on the Internet, and that simply should not be - especially for things that are blurring the line between medical devices that stimulate like a pacemaker and quantified self-sensors like a pedometer or pulse tracker. The mesh of things that we manage must be segmented into zones of trust for sensing data, transmitting data, receiving command and control administrative changes, and peer-to-peer mesh messaging. In his session at @ThingsExpo, Ryan Bagnulo, Solution Architect / Software Engineer at SOA Software, focused on desi...

We certainly live in interesting technological times. And no more interesting than the current competing IoT standards for connectivity. Various standards bodies, approaches, and ecosystems are vying for mindshare and positioning for a competitive edge. It is clear that when the dust settles, we will have new protocols, evolved protocols, that will change the way we interact with devices and infrastructure. We will also have evolved web protocols, like HTTP/2, that will be changing the very core of our infrastructures. At the same time, we have old approaches made new again like micro-services...
