What you need for this book
In order to develop applications for iOS, you need to have a Mac and, preferably, the latest version of Mac OS X. Although an Apple developer account and iOS Developer Program are not necessary, it is recommended as it allows you to run the examples on actual devices such as the iPod Touch, iPhone, and iPad and distribute your applications to the Apple App Store. Keep in mind that the iOS Developer Program comes with additional costs.
There is no need to have Sparrow and Xcode installed on your system; we will cover the installation process in the first chapter.
