Preface
Face it—animations make apps really attractive to users. If your app presents a simple user interface, but only does what it says it does, chances are that users will choose a competitor’s app, one with a better user interface that makes use of iOS SDK’s fantastic animation and graphics capabilities.
This book is written to teach programmers how to incorporate smooth animations, along with skills such as loading custom fonts and drawing images in their apps.
Audience
This book is written for programmers who are fairly new to Cocoa and iOS programming. However, it is assumed that you know basic Objective-C and have done some Cocoa programming. I also assume you know some elementary principles of computer graphics, such as coordinates and the RGB color scheme.
