iOS Development from Beginner to Master

This book is an introductory iOS development tutorial written by Liu Yan and published by Tsinghua University Press in 2017. Using iOS 9.0 and Xcode 6.4 as its development platform, it belongs to the "Web Development Video Lecture Hall" sub-series within Tsinghua University Press's "Video Lecture Hall" series. The book has 24 chapters organized in three parts: language fundamentals, frameworks and interfaces, and comprehensive case studies. Chapters 1–7 begin with the history of iOS, the system architecture, and the Xcode development environment, then successively cover data types and operators, control statements, C language features, classes and objects, messages and protocols, and object ownership and memory management, helping readers with no prior experience first master the Objective-C language. Chapters 8–20 move into frameworks and interfaces, explaining the string, number, date, array, dictionary, and collection classes in the Foundation framework; the core architecture and operating mechanisms of iOS applications; and topics such as windows and views, view controllers, touch and motion events, basic and advanced controls, drawing and animation, multimedia, device management, and file and data operations (including the SQLite database). Chapters 21–24 present four complete case studies—"Grab the Poker," "Electronic Keyboard," "Pac-Man," and "Breakout"—demonstrating through the full process from creating a project and building the interface to writing interaction logic how a small app that runs on both the simulator and a real device is made. The book includes about 200 synchronized video lessons and 102 small and medium examples. It is suitable for readers with no experience in Objective-C or Apple development tools to study on their own in sequence, and can also serve as a textbook for mobile development courses at training institutions and schools.
