Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. It was the main programming language used by Apple for the OS X and iOS operating systems, and their respective application programming interfaces (APIs): Cocoa and Cocoa Touch prior to the introduction of Swift.
The programming language Objective-C was originally developed in the early 1980s. It was selected as the main language used by NeXT for its NeXTSTEP operating system, from which OS X and iOS are derived.Portable Objective-C programs that do not use the Cocoa or Cocoa Touch libraries, or those using parts that may be ported or https://en.wikipedia.org/wiki/Objective-Creimplemented for other systems, can also be compiled for any system supported by GNU Compiler Collection (GCC) or Clang.
Objective-C source code 'implementation' program files usually have .m filename extensions, while Objective-C 'header/interface' files have .h extensions, the same as C header files. Objective-C++ files are denoted with a .mm file extension.
Objective-C was created primarily by Brad Cox and Tom Love in the early 1980s at their company Stepstone. Both had been introduced to Smalltalk while at ITT Corporation's Programming Technology Center in 1981. The earliest work on Objective-C traces back to around that time.
In 1986, Cox published the main description of Objective-C in its original form in the book Object-Oriented Programming, An Evolutionary Approach. Although he was careful to point out that there is more to the problem of reusability than just the language, Objective-C often found itself compared feature for feature with other languages.
Language was licensed in the 1988, and code library called NeXTSTEP was developed.
After acquiring NeXT in 1996, Apple Computer used OpenStep in its new operating system, Mac OS X. This included Objective-C, NeXT's Objective-C based developer tool,Project Builder, and its interface design tool, Interface Builder (both now merged into one Xcode application). Most of Apple's present-day Cocoa API is based on OpenStep interface objects, and is the most significant Objective-C environment being used for active development.
At WWDC 2014, Apple introduced a new language, Swift, which was characterized as "Objective-C without the C".
There are tools associated with every programming language. Below are some of the tools that you can use while working with Objective-C programming language.
As the primary programming language for iPhone, iPad, and Mac OS X applications, Objective-C is a reflective, object-oriented language that all programmers must know before creating apps. Assuming no prior programming language experience, this fun-and-friendly book provides you with a solid understanding of Objective-C. Addressing the latest version of Xcode, debugging, code completion, and more, veteran author Neal Goldstein helps you gain a solid foundation of this complex topic, and filters out any unnecessary intricate technical jargon.

Objective-C is the universal language of iPhone, iPad, and Mac apps, and Objective-C for Absolute Beginners, Second Edition starts you on the path to mastering this language and its latest release. Using a hands-on approach, you'll learn how to think in programming terms, how to use Objective-C to construct program logic, and how to synthesize it all into working apps. Gary Bennett, an experienced app developer and trainer, will guide you on your journey to becoming a successful app developer.
The book makes no assumptions about prior experience with object-oriented programming languages or with the C language (which Objective-C is based upon). Because of this, both beginners and experienced programmers alike can use this book to quickly and effectively learn the fundamentals of Objective-C. Readers can also learn the concepts of object-oriented programming without having to first learn all of the intricacies of the underlying C programming language.
Through real-world examples, Galloway uncovers little-known Objective-C quirks, pitfalls, and intricacies that powerfully impact code behavior and performance. You’ll learn how to choose the most efficient and effective way to accomplish key tasks when multiple options exist, and how to write code that’s easier to understand, maintain, and improve. Galloway goes far beyond the core language, helping you integrate and leverage key Foundation framework classes and modern system libraries, such as Grand Central Dispatch.
Take your coding skills to the next level with this extensive guide to Objective–C, the native programming language for developing sophisticated software applications for Mac OS X. Objective–C is a powerful, object–oriented extension of C, making this book the perfect follow–up to Dave Mark’s bestselling Learn C on the Mac, Mac OS X Edition. Whether you’re an experienced C programmer or you’re coming from a different language such as C++ or Java, leading Mac experts Mark Dalrymple and Scott Knaster show you how to harness the powers of Objective–C in your applications!
You’ll learn how to work with the Xcode IDE, Objective-C’s Foundation library, and other developer tools such as Event Kit framework and Core Animation. Along the way, you’ll build example projects, including a simple Objective-C application, a custom view, a simple video player application, and an app that displays calendar events for the user.

Table Tool The CSV format is a common used file format to store and exchange tabular data. Almost all spreadsheet and database apps (e.g. Excel and Numbers) support it. Unfortunately, not all CSV files are made equal. CSV files use different record delimiters (comma or semicolon), character encodings, decimal separators or quoting styles. TableTool handles these issues automatically. It detects the specification of a CSV file for you and displays its contents in a table view. Using TableTool is the easy way to create, edit and convert CSV files.Explore this project!
CountryPicker is a custom UIPickerView subclass that provides an iOS control allowing a user to select a country from a list. It can optionally display a flag next to each country name, and the library includes a set of 249 public domain flag images from https://github.com/koppi/iso-country-flags-svg-collection that have been renamed to work with the library.Explore this project!
Think of Aspects as method swizzling on steroids. It allows you to add code to existing methods per class or per instance, whilst thinking of the insertion point e.g. before/instead/after. Aspects automatically deals with calling super and is easier to use than regular method swizzling. This is stable and used in hundreds of apps since it's part of PSPDFKit, an iOS PDF framework that ships with apps like Dropbox or Evernote, and now I finally made it open source.Explore this project!
AsyncDisplayKit is an iOS framework that keeps even the most complex user interfaces smooth and responsive. It was originally built to make Facebook's Paper possible, and goes hand-in-hand with pop's physics-based animations — but it's just as powerful with UIKit Dynamics and conventional app designs.Explore this project!
