The Completed View in Interface Builder
In the header for the controller, we add
IBOutlet
references for the
UIImageView
and for
the
UIButton
. We use properties to make it clear that both of these are assignments and
do not need to be released. The header is shown in Listing 13-15.

In addition to the
IBOutlet
references, we have added a
-action:
method call to
IBAction
, which is called when the user presses the button on the view.
