Duration: 5 Days
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 Will 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
Audience
