'=' and '==' are equivalent in predicate format strings (predicates
are queries, so assignment isn't possible)
I should probably have made clear in the first post:
The program returns a list of all tracks that are marked as gapless
from my mp3 collection (and only those marked gapless), the problem is
that those objects all say that the tracks aren't gapless.

Hi,
I've been trying to do some python scripting of iTunes using pyobjc
and ScriptingBridge, and I've been having some problems (I reduced
everything to objective-c on its own in order work out if it was
caused by pyobjc).
According to:
http://developer.apple.com/releasenotes/scriptingautomation/RN-ScriptingBridge/index.html
running:
sdef /Applications/iTunes.app/ | sdp -f h --basename iTunes
should generate an objective-c header file which you can use in
conjunction with [SBApplication
applicationWithBundleIdentifier:@"com.apple.iTunes"]
(which it does).
An excerpt from the file I generated (included in the zip file):
@interface iTunesTrack : iTunesItem
...
@property BOOL gapless; // is this track from a gapless album?
...
@end
So there should be an accessor method on iTunesTrack objects called
gapless that returns a BOOL.
[track respondsToSelector:@selector(gapless)] returns YES
However it doesn't seem to work, the code provided in the zip
archive (when executed on my machine), produces a list of all the
gapless tracks in my mp3 collection, but every line ALSO claims
that the track is 'not gapless'.
(The original python code that I was using seemed to get different
answers depending on ordering of operations, including calling the
accessor twice in a row on the same object giving different answers).
Am I doing something wrong? The other accessors that I call appear
to return the right data, though I've not done exhaustive testing.
(As a background to what I'm doing, I want my iTunes playlists
random except for gapless cds, which I want to be seamless, the
shuffle provided by itunes can't make that distinction for itself).
<tester.zip>
From test.m :
NSPredicate* predicate = [NSPredicate
predicateWithFormat:@"gapless=YES"];
this should probably be : .....
predicateWithFormat:@"gapless==YES"];
