The book is great and has deserved 5 stars.
It is easy to follow with good explanations and exercises and well strctured. The best book that I've read regarding Objective-C programming.
But as the formatting especially with formulas and signs like +, -, *, / and brackets does not work and confuses a lot while try to follow the examples it only gets four stars.
It is also a pitty that the answers to the exercises are not available anywhere. In the official forum there is not category for 6th edition of the book :(
