24.03 The Road to Code: Building on a Solid Foundation

Mar, 2008 Issue

Article Synopsis

Now that we’ve gone over the basics of the Objective-C language, including classes, inheritance, and memory management, we can start to write some real code. One of the great things about developing for Mac OS X is that in addition to getting a nice language to use, you also get a lot of reusable code to use in your own applications. This can save you lots of time because you can reuse what’s already present in the system. Reusable code on Mac OS X is often grouped together in a package called a framework. A framework is similar to a dynamically linked library (DLL) on Windows or a shared object (.so) on most other Unix platforms in that it contains shared code that may be used by multiple applications.
