Is it possible to modify iTunes tracks using 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"]);
