Programming in Objective-C, Sixth Edition

The NSURL Class

The NSURL class provides an easy way for you to work with URL addresses in your program. For example, given an HTTP address that is a path to a file on the Internet, you can easily read the contents of that file with a few method calls. You’ll find many methods in Foundation that take NSURL objects as arguments. Just remember that an NSURL object is not a string object such as @"http:/www.apple.com", but it’s easy to create one from a string object using the URLWithString: method.

Program 16.9 shows how the HTML contents from a Web address can be read into a program.
