Pro iOS Application Architectures presents iPhone, iPad, and iPod touch application architectures for common types of features, including content-driven, web-based, multimedia features. This book provides a solution patterns catalog that contains background, detailed explanations, sample code, and best practices for application needs as varied as asynchronous content retrieval or defining a map overlay. Unlike design patterns, which focus on a microscopic view of software implementation, architectural solutions take a macroscopic view of a software system—in this case, iOS subsystems like networking, content, data, and security.This book not only explains the architectural elements of iPhone and iPad applications, but also helps you select an application architecture and solution so you can save time and ensure a high-quality app.
