Introducing Objective-C and Xcode
Gary F. Bennett, Mitch Fisher, Brad Lees · Apress eBooks · 2010
For the most part, all computer languages perform the typical tasks that any computer needs to do—store information, compare information, make decisions about that information, and perform some action based on that decision. Objective-C is a language to make these tasks easier to accomplish and understand. The real trick with Objective- C (actually the trick with any C language) is understanding the symbols and keywords used to accomplish those tasks. This chapter introduces you Objective-C and Xcode— from Objective-C’s humble beginnings as an extension to the C language to using Xcode (a tool to build programs using Objective-C) to build programs. By the end of this chapter, you will understand what Objective-C is and know how to write a simple application using Xcode. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
