Hi,
I've been struggling to find any information on writing visualizers
for iTunes 10.4. Is there a modern equivalent of the venerable

I have an NSManagedObject with a transformable property

Hi,
I'm in the process of converting an existing iPhone app to use Core
Data for its backend storage. I've got a model that manages an upload
of its own attributes to a server - it has a retained NSURLConnection
instance variable. Traditionally, I'd just release the connection in
the model's dea

Heya,
I'd like to get hold of the top level objects returned by -[NSBundle

Sadly UIViewController doesn't seem to provide any way of accessing

Heya,
I'm struggling a bit with an NSArrayController with content bound to
NSUserDefaultsController.
The NSArrayController manages dictionaries, and so it appears that I
need to select 'Handles Content as Compound Value'. Without this,

Heya,
I ran into a memory leak recently that I finally managed to track down
to NSURLConnection retaining its delegate.
It appears that cancelling an NSURLConnection won't actually release
its delegate until the next time around the run loop. Normally this
is fine, but I was running on a separate

I'm struggling a bit with NSViewControllers. My app displays a list
