Book Review: iOS Components and Frameworks

Understanding the Advanced Features of the iOS SDK

When I first started flipping through this book the diverse set of topics threw me for a loop. Then I read the introduction where the authors say, "This publication aims to provide development information on the intermediate-to-advanced topics that are otherwise not worthy of standalone books. It’s not that the topics are uninteresting or lackluster, it’s that they are not large enough topics."

This book covers a wide variety of topics, and it covers them in enough detail that you have a good understanding of them by the end of the chapter. Only Game Center and Core Data are covered in more than one chapter. The book is not a cover to cover read, but rather a pure reference.

I have listed the chapters below to show you what is covered.

1. UIKit Dynamics
2. Core Location, MapKit, and Geofencing
3. Leaderboards
4. Achievements
5. Getting Started with Address Book
6. Working with Music Libraries
7. Working with and Parsing JSON
8. Getting Started with iCloud
9. Notifications
10. Bluetooth Networking with Game Kit
11. AirPrint
12. Core Data Primer
13. Getting Up and Running with Core Data
14. Language Features
15. Integrating Twitter and Facebook Using Social Framework
16. Working with Background Tasks
17. Grand Central Dispatch for Performance
18. Using Keychain to Secure Data
19. Working with Images and Filters
20. Collection Views
21. Introduction to TextKit
22. Gesture Recognizers
23. Accessing Photo Libraries
24. Passbook and PassKit
25. Debugging and Instruments

One thing that you should be made aware of is that the authors decided to present all their examples in the book without using Automatic Reference Counting (ARC). At the time of this review all the chapters have non-ARC code samples are available, and only 9 of them have sample code using ARC.

They said the reason for not using ARC is that it is easier to mentally remove the memory management than to add it. Personally I find it annoying, but it isn't that big of a deal. The authors do cover ARC in chapter 14 along with literals, properties, blocks, fast enumeration, and method swizzling.

The authors' writing styles make the topics easy reads, and they do a great job of explaining things, but this book is for someone very comfortable with iOS, Xcode, Objective-C, the Developer's Portal, iTunes Connect, and Instruments. Although the authors do cover some of the basics in a few chapters, and includes a primer on Core Data, most of the topics assume the reader has some prior working knowledge about the topic at hand.

Over all I found this book worth the shelf space. I had an immediate need for more information on a few of the topics they included in the book and was satisfied with the coverage they included. I did have to dig for more information on the topics, but I had solid ground to stand on and knew what else I needed to find.

If you are an iOS developer, and are using Xcode, this book will at some point offer you information on a topic you need to get your head around quickly.

As people view cloud as a preferred option to build IT systems, the size of the cloud-based system is getting bigger and more complex. As the system gets bigger, more people need to collaborate from design to management. As more people collaborate to create a bigger system, the need for a systematic approach to automate the process is required. Just as in software, cloud now needs DevOps. In this session, the audience can see how people can solve this issue with a visual model. Visual models ha...
Enterprises are adopting Kubernetes to accelerate the development and the delivery of cloud-native applications. However, sharing a Kubernetes cluster between members of the same team can be challenging. And, sharing clusters across multiple teams is even harder. Kubernetes offers several constructs to help implement segmentation and isolation. However, these primitives can be complex to understand and apply. As a result, it’s becoming common for enterprises to end up with several clusters. Thi...
Containers are rapidly finding their way into enterprise data centers, but change is difficult. How do enterprises transform their architecture with technologies like containers without losing the reliable components of their current solutions? In his session at @DevOpsSummit at 21st Cloud Expo, Tony Campbell, Director, Educational Services at CoreOS, will explore the challenges organizations are facing today as they move to containers and go over how Kubernetes applications can deploy with lega...
Today most companies are adopting or evaluating container technology - Docker in particular - to speed up application deployment, drive down cost, ease management and make application delivery more flexible overall. As with most new architectures, this dream takes significant work to become a reality. Even when you do get your application componentized enough and packaged properly, there are still challenges for DevOps teams to making the shift to continuous delivery and achieving that reducti...
Transforming cloud-based data into a reportable format can be a very expensive, time-intensive and complex operation. As a SaaS platform with more than 30 million global users, Cornerstone OnDemand’s challenge was to create a scalable solution that would improve the time it took customers to access their user data. Our Real-Time Data Warehouse (RTDW) process vastly reduced data time-to-availability from 24 hours to just 10 minutes. In his session at 21st Cloud Expo, Mark Goldin, Chief Technolo...
Is advanced scheduling in Kubernetes achievable? Yes, however, how do you properly accommodate every real-life scenario that a Kubernetes user might encounter? How do you leverage advanced scheduling techniques to shape and describe each scenario in easy-to-use rules and configurations? In his session at @DevOpsSummit at 21st Cloud Expo, Oleg Chunikhin, CTO at Kublr, will answer these questions and demonstrate techniques for implementing advanced scheduling. For example, using spot instances ...
We all know that end users experience the Internet primarily with mobile devices. From an app development perspective, we know that successfully responding to the needs of mobile customers depends on rapid DevOps – failing fast, in short, until the right solution evolves in your customers' relationship to your business. Whether you’re decomposing an SOA monolith, or developing a new application cloud natively, it’s not a question of using microservices – not doing so will be a path to eventual b...
Digital transformation leaders have poured tons of money and effort into coding in recent years. And with good reason. To succeed at digital, you must be able to write great code. You also have to build a strong Agile culture so your coding efforts tightly align with market signals and business outcomes. But if your investments in testing haven’t kept pace with your investments in coding, you’ll lose. But if your investments in testing haven’t kept pace with your investments in coding, you’ll...

DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die. A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm. In their Day 3 Keynote at 20th Cloud Expo, Chris Brown, a Solutions Marketing Manager at Nutanix, and Mark Lav...

A common misconception about the cloud is that one size fits all. Companies expecting to run all of their operations using one cloud solution or service must realize that doing so is akin to forcing the totality of their business functionality into a straightjacket. Unlocking the full potential of the cloud means embracing the multi-cloud future where businesses use their own cloud, and/or clouds from different vendors, to support separate functions or product groups. There is no single cloud so...
For most organizations, the move to hybrid cloud is now a question of when, not if. Fully 82% of enterprises plan to have a hybrid cloud strategy this year, according to Infoholic Research. The worldwide hybrid cloud computing market is expected to grow about 34% annually over the next five years, reaching $241.13 billion by 2022. Companies are embracing hybrid cloud because of the many advantages it offers compared to relying on a single provider for all of their cloud needs. Hybrid offers bala...
With the modern notion of digital transformation, enterprises are chipping away at the fundamental organizational and operational structures that have been with us since the nineteenth century or earlier. One remarkable casualty: the business process. Business processes have become so ingrained in how we envision large organizations operating and the roles people play within them that relegating them to the scrap heap is almost unimaginable, and unquestionably transformative. In the Digital ...
These days, APIs have become an integral part of the digital transformation journey for all enterprises. Every digital innovation story is connected to APIs . But have you ever pondered over to know what are the source of these APIs? Let me explain - APIs sources can be varied, internal or external, solving different purposes, but mostly categorized into the following two categories. Data lakes is a term used to represent disconnected but relevant data that are used by various business units wit...
The nature of the technology business is forward-thinking. It focuses on the future and what’s coming next. Innovations and creativity in our world of software development strive to improve the status quo and increase customer satisfaction through speed and increased connectivity. Yet, while it's exciting to see enterprises embrace new ways of thinking and advance their processes with cutting edge technology, it rarely happens rapidly or even simultaneously across all industries.
