Beside the things that has been mentioned in this thread so far, you
might also want to have a look at:
-[NSString writeToFile:atomically:encoding:error:] (Writing), and
+[NSString stringWithContentsOfFile:encoding:error:] (Reading)
NSData, NSArray and NSDictionary also have similar simple ways to
read to / write from files.
Archiving and data serialization topics will probably also be of
interest:

<http://developer.apple.com/documentation/Cocoa/Conceptual/
PropertyLists/index.html>
See also the recommendations for where to store user data in the file
system, and how to locate these special locations:

Finally, if you're thinking about persistence of user preferences and
other small snippets of per-user data you should use NSUserDefaults
and not your own file based storage.
