Just call the "get" method on the track object that currentTrack
returns to get the iTunesFileTrack object. I.e. this works
iTunesFileTrack *currentTrack = [[iTunes currentTrack] get];
NSLog("location is %@", currentTrack.location);
The documentation for the "get" method from the SBObject.h header is:
// Evaluate the object by sending it to the target application.
Depending on what
// the object points to, the result may be a Foundation object such
as an NSString
// (for most properties), an NSAppleEventDescriptor (for properties
of a type with
// no Foundation equivalent), or another SBObject (for most elements).
Another example of where you need to use it in the iTunes SB interface
is when accessing iTunes.selection property, which returns an
SBObject, but then if you call "get" on it, you get an NSCFArray of
tracks, which is what you wanted in the first place. I'm not sure
what the logic is behind the "get" method, but there it is.

Hello!
I want to retrieve the path to the currently played file in iTunes.
I thought scripting bridge would be the perfect tool for this,
however i've run into some problem. I have this code:
iTunesApplication *iTunes = [[SBApplication alloc]
initWithBundleIdentifier:@"com.apple.iTunes"];
iTunesTrack *currentTrack = [iTunes currentTrack];
if ([currentTrack isKindOfClass:[iTunesFileTrack class]]) {
…
}
The problem is, that the class of the object returned is _always_
iTunesTrack, and not iTunesFileTrack, as i expect it to be. If i run
the following applescript code:
tell application "iTunes" to current track
I get a "file track", which makes it possible to fetch the path
using the "location" attribute. If I, in the ObjC example, try
[currentTrack location], I'm told that it doesn't respond to that
selector.
I have made certain that the object is of class iTunesTrack by
typing 'po [currentTrack class]' in gdb.
Very thankful for help!
