Excellent Free Tutorials to Learn Objective-C

Last Updated on December 24, 2022

Objective-C is a general purpose programming language which is a superset of the C programming language and provides object-oriented capabilities and a dynamic runtime. Objective-C inherits the syntax, primitive types, and flow control statements of C and adds syntax for defining classes and methods.

It also adds language-level support for object graph management and object literals while providing dynamic typing and binding, deferring many responsibilities until runtime. Objective-C can incorporate blocks of C code (as well as C++), making it very versatile for application development.

Objective-C is the primary programming language used when writing software for OS X and iOS.


1. Learn Objective-C in Y minutes by Eugene Yagrushki and contributors

This is one in a whole series covering a wide range of programming languages, released under a Creative Commons license.

2. Objectively Speaking: A Crash Course in Objective-C for iOS 6 by Razeware

This tutorial uses the Modern-Objective-C syntax.

3. Objective-C Runtime by Apple

Objective-C Runtime describes the macOS Objective-C runtime library support functions and data structures.

The Objective-C runtime is a runtime library that provides support for the dynamic properties of the Objective-C language, and as such is linked to by all Objective-C apps.

Because this isn’t a document about C, it assumes some prior acquaintance with that language.

4. Programming with Objective-C by Apple

This document introduces the Objective-C language and offers extensive examples of its use. You’ll learn how to create your own classes describing custom objects and see how to work with some of the framework classes provided by Cocoa and Cocoa Touch.

Although the framework classes are separate from the language, their use is tightly wound into coding with Objective-C and many language-level features rely on behavior offered by these classes

5. Introduction to Objective-C Programming by Will Harrison

Part 1 looks at:

  • Object-oriented programming
  • Classes and instances
  • Inheritance and Class Hierarchy
  • Objective-C syntax
  • Differences between C/C++ and Objective-C
  • Method composition and invoking
  • Nested methods

Part 2 examines creating our own classes, as well as writing our first bit of code in Objective-C.

6. Ry’s Objective-C Tutorial by Ryan Hodson

This book serves as both a concise quick-reference and a comprehensive introduction for newcomers to the Objective-C programming language. It walks through each language feature step-by-step, explaining complex programming concepts via hands-on examples.

This tutorial focuses solely on the programming language, rather than on iOS or Mac App development. You won’t walk away with the ability to create your own iPad apps, but you will be prepared to continue down that path.
