Do you think anyone in the review http://oreilly.com/catalog/0636920010180#reviews downloaded the sample code and compiled any one of the projects with Xcode 4 or 3.2 with iOS SDK 4.x? I am wondering how someone who does not even try to compile the sample codes posts their review to a programming book? I don't think they even understand Objective-C.

The configuration of all the projects are mess, so you have to reconfigure all the projects to compile. I hope this problem to be fixed ASAP.

Thanks,
