This book follows a recipebased approach that will heavily focus on the code and how to integrate the samples with the reader’s projects.Each recipe consists of one or more methods that you can put directly into your app and use. This book is ideal for developers that want to create network applications for the Apple OS X or iOS platforms. All examples are written in ObjectiveC using XCode as the IDE. Knowledge of ObjectiveC and XCode is essential.
