it's not getting called at all. Is it because my method is defined
in category? As I wrote already, I'm able to call my methods from
gdb so my category is up and running
NSLog(@"%@", [[[ppl arrangedObjects] objectAtIndex:0] lastName]);
as opposed to
Value (ABPeople.arrangedObjects.lastName)
Because the view uses a binding, it's actually going to call
'valueForKeyPath:@"lastName"', isn't it? Normally, you'd expect that
to end up at your 'lastName' method via [NSObject valueForKey:], but
since it isn't getting to your custom accessor, you know that
'valueForKey:@"lastName"' is itself returning nil or an empty string.
This suggests to me that ABRecord (the superclass of ABPerson, the
documentation says) may override valueForKey: with new behavior that
doesn't call custom accessors or return anything useful. If that's so,
I can only speculate that it's to prevent you using valueForKey when
you're "supposed" to use valueForProperty instead.
Does that sound plausible?
