Assignment #3: Connecting to the Network

This is another multi-part assignment, involving more than one app. To complete the assignment, read Chapter 7 of the textbook and complete the apps described there. As usual, don’t rely on a URL provided by the author (like the one for the Apple’s Reachability code); google it yourself.

As an example of possible extra credit, consider implementing the asynchronous reachability feature described on pages 174-176. As I noted in the blog, there appears to be a problem in the way in which the author tries to do this!
