iOS Programming

This book is the Chinese translation of the classic iOS development tutorial in the Big Nerd Ranch training series, originally titled iOS Programming: The Big Nerd Ranch Guide, drawn from the institution's highly acclaimed textbook for its "iOS beginner training course." The Chinese text starts with the fundamentals of the Objective-C language, extends to its newer features, and then works layer by layer into the AppKit framework, common Cocoa design patterns, Xcode development tool techniques, and the use of the Instruments performance analysis tool, striving to cover the complete range of knowledge needed to develop an iOS app. Unlike ordinary manuals that list APIs, this book emphasizes "solving problems the right way": what conventions Objective-C follows (such as naming conventions and memory management conventions), how to handle initializer methods when creating subclasses, which design patterns recur in Cocoa, and how to choose how data should be saved in an app. These lessons, if left for readers to figure out on their own by piecing together scattered documentation, often cost much time and effort; the book organizes, summarizes, and presents them clearly. The whole book is organized around practice: readers new to iOS programming can read the first two chapters and immediately build a small working app to gain a quick overall impression; those with some iOS experience can read the whole book to fill gaps and complete blind spots. Whether you are developing a brand-new app or adding features to an existing one, most problems can be answered or addressed in this book. The series has won a Jolt Productivity Award and is a hands-on read worth revisiting at both the introductory and advanced stages of iOS.
