Apple’s iOS SDK provides an amazingly powerful collection of frameworks. But it has been difficult to find detailed and useful knowledge about them–until now. With this book’s practical insights and tested code, you can use Apple’s frameworks to create apps that are more innovative and usable…faster and more reliable…more successful and profitable.
Kyle Richter and Joe Keeley focus on intermediate-to-advanced techniques that professional iOS developers can use every day. Their far-reaching coverage ranges from social support to security, Core Data to iCloud–even Apple Watch.
Organized as a convenient modular reference, nearly every chapter contains a complete Objective-C sample project. A multi-chapter Game Center case study shows how multiple iOS features can be combined to do even more.
