Here are the missing connections:
•
QuizViewController
, the controller object, must have pointers to the
UILabel
instances so it can tell them what to display.
• The
UIButton
instances must have pointers to the
QuizViewController
so they can send messages to the controller when tapped.
Setting pointers

UILabel
instances. The instance of
QuizViewController
has a pointer called
questionField
. You want
ques-
tionField
to point to the instance of
UILabel
at the top of the view.
