You Will Learn How To
- Create, compile and run Objective-C programs using Xcode
- Build applications by applying Objective-C language constructs, syntax and semantics
- Implement object-oriented designs using encapsulation, inheritance and polymorphism
- Leverage the Foundation Framework class libraries
- Develop graphical user interfaces (GUIs) for Mac OS X using the Cocoa framework
- Program a simple iPhone/iPad application using the Cocoa Touch framework
Course BenefitsObjective-C is critical to Mac, iPhone and iPad application development. In order to create increasingly powerful and sophisticated software, programmers need to delve into the framework and architecture of Objective-C. Throughout this course, you learn the fundamental programming concepts of Objective-C and the Foundation Framework used to develop code for the Mac OS X and iOS platforms.
Who Should AttendProgrammers, application developers and anyone interested in writing applications for Apple platforms. Programming experience with a modern language such as Java, C, C++, C# or Visual Basic is required. Object-oriented programming experience is recommended.
Hands-On TrainingThroughout this course, you perform a series of exercises to gain experience programming with Objective-C. Exercises include:
- Writing and compiling Objective-C programs using Xcode
- Managing objects with Foundation Framework collection classes
- Extending classes with inheritance
- Enhancing classes with categories when inheritance is inappropriate
- Writing loosely coupled applications with protocols
- Building GUI apps for the Mac with the Cocoa framework
- Creating a simple app for iPhones and iPads with the Cocoa Touch framework
