Adding Multimedia Playback Capability
Tasks to Accomplish
The tasks you want to accomplish in adding this new functionality to your QTKitPlayer application
are less complex than those in the previous chapter. You’ll build on the existing QTKitPlayer, using
the tools available to you in Interface Builder 2.5 and Xcode 2.0. The code you’ll need to add to the
project in order to make it work will be surprisingly simple—but powerful. You’ll do this:
1. Add a View Tests Window to your MainMenu.nib in Interface Builder and populate that window
with the QTMovieView objects you need to display QuickTime movies, as indicated in Figure
6-3.
2. Specify the attributes of the View Tests Window you’ve added to the nib.
3. Subclass NSObject with a ViewTestsController class in your MainMenu.nib and wire it up with
outlets and actions to handle the opening and display of movies in the View Tests Window.
4. Add to your Xcode project a new ViewTestsController.h declaration file in which you define
the instance variables and actions for your ViewTestsController class.
5. Add an ViewTestsController.m implementation file to your QTKitPlayer project in which you
handle getting and setting the movies you want to play, notifications, stopping and clearing the
movies that are playing, and adding a toolbar which can be shown or not shown.
6. Add a new menu title to the QTKitPlayer and a menu item to open the window
