Is it possible to modify iTunes tracks using Objective-C? - objective-c

Question

The question is in the title :) I'm playing a bit with Objective-C and Scripting Bridge. I know it is possible to get information (readonly) from iTunes, but i see nowhere a way to modify a track, for exemple change its name. Is it possible with this or another technology ?
Thanks a lot :)

Answer 1

Well, from the Scripting Library in AppleScript Editor, I can see that a file_track inherits from item and an item has the read-write property name. So you should be able to set it just as easily as you can read it.
Edit: Actually, almost every piece of meta-data is part of track (of which file_track inherits aswell) and most are read-write properties...
Doug Adams has one such script which can change titles from song in iTunes. Maybe have a look at it?
As for setting it via Objective-C, perhaps this documention can help you.
Exerpt from the website:
Listing 2-3 Setting the locked property of Finder items
int main (int argc, const char * argv[]) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
FinderApplication *theFinder = [SBApplication applicationWithBundleIdentifier: #"com.apple.finder"];
SBElementArray *trashItems = [[theFinder trash] items];
if ([trashItems count] > 0) {
for (FinderItem *item in trashItems) {
if ([item locked]==YES)
[item setLocked:NO]; // <<<-- Setting the property
}
}
[pool drain];
return 0;
}
Have you tried:
iTunesApplication *iTunes = [SBApplication applicationWithBundleIdentifier:#"com.apple.iTunes"];
[[iTunes currentTrack] setName:#"The New Song Title"]);
