Now I am developing an cocoa application. One of the app's
function is to
synchronize the audio and video files to the iPod/iPhone. The
function is same
as the "iTunes Syncing" function.
You have no access to the user's iTunes or iPod libraries.
It's possible, though quite difficult, for a desktop app to access the
music library on an iPod. There are 3rd party apps such as PodWorks
and Senuti that do it. From what I've heard, I believe it would take a
lot of frustrating work to implement similar functionality, especially
since Apple has lately begun encrypting the library database file on
the iPod.
For the iPod Touch and iPhone, it's pretty much impossible. The older
iPods mount as dumb hard-drives, but iPhone OS devices use a custom
protocol over USB, which Apple has locked down as tightly as they can
to discourage messing with the phone's OS and apps.
An app running on an iPhone (or iPod Touch) can look at the device's
music library using the media framework, and can play tracks, but has
no ability to modify the library at all. So syncing is not possible.
