Learning Objective-C and Xcode
For the most part, all computer languages perform the typical tasks any computer needs to do—store information, compare information, make decisions about that information, and perform some action based on those decisions. Objective-C is a language that makes these tasks easier to understand and accomplish. The real trick with Objective-C (actually, the trick with any C language) is to understand the symbols and keywords used to accomplish these tasks. This chapter continues our examination of Objective-C and Xcode so you can become even more familiar with them.
