Sample code is never a fixed target. Get involved. Github allows you to fork repositories and grow them with your own tweaks and features, and share those back to the main repository. If you come up with a new idea or approach, let us know. Although each programmer brings different goals and experiences to the table, most iOS developers end up solving similar tasks in their development work: "How do I build a table?
Offering a single file concentrates that story, allowing access to that idea in a single chunk. These samples are not intended as stand-alone applications.
They are there to demonstrate a single recipe and a single idea. A main. Readers can study these concentrated ideas and transfer them into normal application structures, using the standard file structure and layout. The presentation in this book does not produce code in a day-to-day best practices approach.
Instead, it offers concise solutions that you can incorporate back into your work as needed. Those samples are built as full applications, often doing tasks that are related to but not essential to what you need to solve, with many distracting flourishes.
Finding relevant portions is a lot of work. The effort may outweigh any gains. There are two exceptions to this one-file rule. The walk through folders may therefore contain a dozen or more files at once. Second, standard implementation and header files are provided when the class itself is the recipe.
Instead of highlighting a technique, some recipes offer pre-cooked class implementations and categories that is, extensions to a pre-existing class, rather than a child class. For those recipes, look for separate.
How to build these projects You should be able to build these projects for the simulator or use your team provision to build and deploy to devices. Before compiling, make sure you select a deployment target using the pop-up menu at the top-left of the Xcode window. For the most part, the samples for this book use a single application identifier, com.
This book uses one identifier to avoid clogging up your iOS device with dozens of samples at once. Each sample replaces the previous one, ensuring that SpringBoard remains relatively uncluttered. If you want to install several samples at once, simply edit the identifier, adding a unique suffix, such as com. Samples use the same icons and launch images as well.
