Leading iOS authors Maurice Sharp, Erica Sadun, and Rod Strougo offer the perfect hands-on introduction to iOS development, covering everything your students need to know about Objective-C, XCode, and modern iOS user interface development. With hands-on sample projects and end-of-chapter exercises, this book is ideal for classroom instruction. The authors get started fast with Objective-C, covering basic syntax, memory management, Foundation Classes, development paradigms, blocks, threads, and more. Next, they show how to use XCode and related tools to build projects, instrument and efficiently debug code, and deploy apps. In Part III, they turn to interfaces, covering design, content construction, View Controllers, Views, Animations, Touch, Table Views, and even a "taste" of Core Data.
