A subset topic in Objective-C/Cocoa, Graphics and Animation guides the reader on one of the most daunting subjects for a beginner, CoreAnimation, Core Graphics and UIKit Drawing. Vandad Nahavandipoor dedicates his book to the UI aspect, focusing on parts which are just touched upon in the more general iOS books, such as working with UIFonts, Gradient Drawing, as well as the more complex 3D Transformation and moving of objects along paths.
While you can get the general concepts from a more general O'Reilly book, I think focusing a book on this topic allows the reader, including myself, to devote enough attention rather than just skimming a chapter, by providing an entire book, although I must be a bit disappointed with the amount of animation versus the time the author spends on graphics. But on the other hand, I should probably take a CoreAnimation book, which should be a book in itself, so it's probably appropriate to focus on the Graphics aspect and this book is ideal for novice iOS developers.
I would recommend this book as part of a suite of books that are essential, without the illusion that this book will cover all you need with animation, but sufficient depth in Graphics/UIKit to give you a good solid background. [box type="bio"]
