iOS Programming (6th Edition)

iOS Programming (6th Edition) is the Chinese translation of Big Nerd Ranch's popular introductory iOS training course, originally published as iOS Programming: The Big Nerd Ranch Guide. Built around iOS 10, Xcode 8.1, and Swift 3, the book follows a learn-by-doing approach that guides readers through a complete project, gradually building the full skill set from interface construction to data storage. It opens with a small app called Quiz that ushers readers into Xcode: creating a project, understanding model-view-controller (MVC), building interfaces with Interface Builder, running on the simulator, and wiring up IBOutlet and IBAction connections. It then covers Swift fundamentals (type inference, optionals, enumerations, loops, and string interpolation) before moving on to core topics such as views and the view hierarchy, Auto Layout constraints, text input and delegation, view controllers, and building interfaces and constraints in code. Later chapters address localization and internationalization, view animation, debugging with LLDB, UITableView with editing and custom cells, UIStackView, UINavigationController navigation, and features such as the camera and photo picker. Each chapter ends with beginner, intermediate, and advanced exercises that extend the concepts into real-world scenarios. The book pursues two main goals: covering as much of the essential knowledge for iOS app development as possible, and teaching readers to solve problems "the right way," including naming and memory management conventions, subclass initializers, common Cocoa design patterns, and trade-offs among data persistence options. The first two chapters are enough for beginners to get up and running quickly, while experienced developers can use the book to fill in gaps.
