→Finding the Foundation Framework Documentation
A detailed overview of every class and method in the Foundation Framework is beyond the scope of this book and would be largely redundant given that this information is already provided by Apple in various locations. Instead, this book will focus on teaching you how to use the most common Foundation classes to work with numbers, strings and file systems. This knowledge, combined with the Apple Foundation documentation should be all you need to be begin working proficiently with these classes.
The Foundation documentation may be accessed either via the Apple web site, or from within the Xcode development environment (accessed via the ''Help->Documentation'' menu option and listed under Foundation Framework Reference).In addition, you can right click on a Foundation class name in the Xcode editor window and choose ''Find Selected Text in API Reference'' to find the documentation for that class. Alternatively, open the ''Help->Documentation'' window and enter the name of the class into the search text field.
The Framework Reference Documentation lists all the classes available and for each class describes in detail what the class does and what methods are available. In the following chapters we will look in detail at how to work with some of these classes.
