Comprehensive Study of Objective-C

Learn the fundamentals of programming through Objective-C and the iOS SDK.

In this course, you will learn Objective-C and the iOS SDK by establishing the most important programming fundamentals. You'll become familiar with the Xcode Integrated Development Environment and gain a better understanding of the history of Objective-C by brushing-up on ANSI-C. You'll discover the compiler pipeline starting with the preprocessor and progressing through the linker. You will cover the fundamentals of ANSI C and Objective-C and get a solid background for learning iPhone and iPad development.

What You'll Learn

  • Work efficiently and creatively in Objective-C
  • Fundamentals of ANSI C programming
  • Object-oriented programming with Objective-C classes, objects, methods, messages, instance variables, and more
  • How Objective-C actually works to help you when you are trying to learn a new feature of Objective-C
  • Resolve a problem in the debugger


Who Needs to Attend

Programmers and non-programmers wanting to firmly establish fundamental programming theory and practice


Some programming experience is recommended
