iOS Auto Layout Demystified

Auto Layout re-imagines the way developers create user interfaces. It provides a flexible and powerful system that describes how views and their content relate to each other and to the windows and superviews they occupy. In contrast to older design approaches, this technology offers incredible control over layout with a wider range of customization than frames, springs, and struts can express. In this guide, Erica Sadun, bestselling author of The Core iOS 6 Developer's Cookbook and The Advanced iOS 6 Developer's Cookbook, helps readers learn how to use Auto Layout effectively, even masterfully, by providing an abundance of examples alongside plenty of explanations and tips. Instead of struggling with class documentation, you learn in simple steps how the system works and why it’s far more powerful than you first imagined. You read about common design scenarios and discover best practices that make Auto Layout a pleasure rather than a chore to use. Sadun includes examples of non-obvious ways to use Auto Layout to build interactive elements, animations, and other features beyond what you might normally lay out in Interface Builder to help expand the reader’s design possibilities. With this book you will learn The basic concepts that form the foundation of Auto Layout How to create clear and satisfiable rules of your layout, called constraints How to work effectively with the Interface Builder Layout What visual constraints look like, how to work with them, and how they are used in your projects How to debug constraints How to design interfaces when working with Auto Layout Effective solutions to the most common real-world problems and challenges Approximately 238 pages.
