Forgive my ignorance here....
In the view wants to show the "About Box": the view calls
[[AboutBoxController alloc] init] and then
presentModalViewController:animated:.
Does the following (from Apple's documentation [1]) mean that the
calling view *does not* need to release? I was under the impression
that I was responsible for releasing everything I alloc'd.
"dismissModalViewControllerAnimated: ... If you want to retain
a reference to the receiver’s modal view controller, get the
value in the modalViewController property before calling this
method."
