This book is suitable to understand the functionalities of iOS API comprehensively and shallowly. If readers are not familiar with Objective-C language and how to operate the user interface of xcode, they can create first application steadily. Because there are not too much examples, readers can grasp the overview of iOS API.

In my impression, this book doesn't have enough images and figures to understand what views are showed in UI as the result and how to operate the xcode UI. If next version is revised to contain more graphical information, it would help readers to understand more effectively.
