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!
