Extending the QT<strong>Kit</strong>Player Application<br />
If you’ve built the simple QT<strong>Kit</strong>Player application described in the previous chapter, you are now<br />
ready to extend its functionality by following the steps outlined in this chapter. If you skipped the<br />
previous chapter, you may want to familiarize yourself with the section “Working With the QT<strong>Kit</strong><br />
Palette” (page 21), which introduces the new Cocoa-QT<strong>Kit</strong> palette available in the <strong>QuickTime</strong> <strong>Kit</strong><br />
framework. This chapter assumes that, at very least, you have:<br />
■ A basic knowledge of Cocoa development as well as the fundamentals of the Objective-C<br />
programming language<br />
■ An understanding of Xcode, Interface Builder, and the QT<strong>Kit</strong> palette<br />
When completed, your extended QT<strong>Kit</strong>KPlayer application will allow you not only to open and play<br />
<strong>QuickTime</strong> movies, but also to import and export them, as shown in Figure 3-1.<br />
This added capability means that your application will be able to import and display a wide range<br />
of media types that <strong>QuickTime</strong> understands and supports in Mac OS X, including but not restricted<br />
to MP4 clips, JPEG images, and audio files, as you can see in the illustration in Figure 3-2 (page 31).<br />
In so doing, your application moves beyond a simple media player and provides useful functionality<br />
for handling a variety of media types and playback tasks.<br />
