In-Depth Information
Unlike Quiz and Whereami , this application will have two subclasses of UIViewCon-
troller - one called HypnosisViewController and another called
TimeViewController . Each view controller will control a view, and users will be
able to swap between the views depending on whether they want to be hypnotized or just
want to see what time it is. The swapping will be handled by another class, UIT-
abBarController . We'll get to tab bar controllers in the second part of this chapter
after we create the two view controllers.
