It's time to capitalize on your mastery of Cocoa with Pro Objective-C Design Patterns for iOS. You've developed apps that impressed and performed, and now you're ready to jump into development practices that will leave you with more effective, efficient, and professional level apps. This book is the element you need to make the jump from journeyman to master. All too often, developers grind through building good apps on willpower and a vigorous focus on code development, leaving them unaware of and unable to benefit from the underlying structural and functional design patterns. Pro Objective-C Design Patterns for iOS will teach you those design patterns that have always been present at some level in your code, but were never recognized, acknowledged, or fully utilized. Implementation of specific pattern approaches will prove their value to any developer working in the iOS application arena. You'll learn to master classic patterns like singleton, abstract factory, chain of responsibility, and observer. You'll also discover less well-known but useful patterns like memento, composite, command, and mediator. What you'll learn The basic concepts of various design patterns How to apply design patterns to your code based on different scenarios How design patterns can strengthen your apps Who this book is for Any professional or aspiring iOS developer will find productivity, efficiency, and effectiveness of software development enhanced by the methods and practice delivered by Pro Objective-C Design Patterns for iOS. Table of Contents Hello, Design Patterns! A Case Study: Designing an App Prototype Factory Method Abstract Factory Builder Singleton Adapter Bridge Façade Mediator Observer Composite Iterator Visitor Decorator Chain of Responsibility Template Method Strategy Command Flyweight Proxy Memento

Descrizione prodotto
L'autore
Carlo Chung is a computer scientist, tinkerer, and amateur photographer. He earned a master's degree in computer science, specializing in computer vision (a branch of artificial intelligence). Any idea about putting A.I. and any small gadgets together can get him excited. He likes daydreaming about making the iPhone more "intelligent" and "humanoid". He applied his knowledge of computer vision to the iPhone platform and created several apps, two of which have been featured on the front page of the App Store, with one on the top-paid list in the Photography category. When he is away from his keyboard, you may see him playing a part in a drum circle or out in the field prospecting for gold.

ho preferito averlo su carta piuttosto che leggerlo sul pdf che si trova in giro, è il reference per programmare nei linguaggi Apple

Poorly written, slow-paced, repetitive.

If you're looking for a book that clearly and concisely describes design patterns, then look elsewhere.
I was really hoping that this book would offer an updated take on the design patterns covered in the classic "Gang of Four" book (Design Patterns: Elements of Reusable Object-Oriented Software), but written in the context of iOS. Unfortunately, "Pro Objective-C Design Patterns for iOS" doesn't deliver.
Here's why:
1) English is clearly not the author's first language. Many grammatical mistakes, "Engrish" and rambling sentences can be found on every page. The code samples themselves are OK, but the editing and proofreading of the prose are abysmal. I doubt whether anyone at the publisher even read this book before its release.
2) The book is extremely repetitive in places. Entire pages are filled with words that say almost nothing. Here's an example:
"NSNumber is an example of <the> Abstract Factory implementation. This flavor of Abstract Factory in the Foundation framework is referred to by the term 'Class Clusters.' Class Clusters are a design pattern that is commonly found in the Foundation framework. They are based on the idea of the Abstract Factory pattern."
3) Each chapter is usually prefaced with really poor analogies that you have to slog through before getting to any content.
4) There's no original thought. Every design pattern mentioned was originally described (far better, I might add) in the "Gang of Four" book. At least the author credits the original, but why would I want to read a poorly re-hashed version of someone else's ideas?
The book is really slow and contains relatively little code. I expect a "Pro" book to be written for professional developers, not beginners.
Do yourself a favor, and skip this one.

Practical patterns and usage

First, this is not a pure "patterns" book that you might study from in college. To me, it was focused more on the practical every-day iOS developer (and not the computer scientist). If you want a patterns book, just get the GoF like everyone says.
This book does two things well: it covers many patterns that are frequently used in the Cocoa Touch framework (and it really digs into the details) and it covers in a very practical manner how to use a given pattern on iOS. For an example of the former, consider the multi-page discussion in Ch 20 on how NSInvocation plus NSUndoManager combine to make an awesome impl of the Command pattern. For an example of the latter, there is a great section in Ch 8 on how to use the Block construct in Objective-C to impl an Adapter pattern.
I agree with the other reviewers that some editing for proper english was lacking in places, but I didn't find it to be noticeable while reading the text. Also, each pattern chapter opens with a half-page "story" to help describe the pattern. The stories are lame, but easily ignored. Not without some minor flaws, but it's definitely better than most of the iOS-related stuff on the market.

Passable content but poor writing.

My fault for not reading the reviews of others who have flagged the issue of writing quality: It is bad...
The content was actually okay but the writing was so distracting that after getting about 1/4th of the way into the book, I had to skim the rest only looking at the code and UML to extract the knowledge I sought -- which ended up being a better solution than actually plowing through all the muck to the end. Less irritating. I should add that while the bulk of the writing is very messy, some parts, such as the opening paragraphs of some chapters, are not bad at all. Which seems to suggest some major negligence on behalf of whomever was responsible for the final approval for publishing -- as it seems that only the beginnings of chapters were checked. Overall, it's not a consistent style, and a reader should not have to put up with switching their brain in and out of 'rocky reading' mode.
Not a ton of money spent (Kindle version) but I still regret buying this book in the end because when you strip away all of the fluff the core content is not presented in any particularly original way and you can easily find all of these patterns presented in the same manner in various places online (Including Apples own design pattern reference docs which touch on almost all of the patterns presented in this book).
Nothing is perfect, I get it. But people should at least put their best effort forward when putting their name on a product. This book could be a whole lot better. And if the author decides to provide a major update (and get someone to clean up the writing) I will give a better review/rating.
