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.
