I am fairly new to Cocoa (but not programming). I have a data model
containing an entity with a String attribute representing a path to a
folder. I am trying to use IB to bind an NSPathControl widget to the
attribute in the window controller. I assume I need a value
transformer to convert NSURL to String and back. I have written a
crude one to do this, but it fails. In IB I have set the content path
to the attribute name and the value transformer to the name of the
transformer class. When I run the app the transformer is called during
initialisation, but the value passed is an instance of NSCVString,
which makes no sense to me.
Has anyone any idea what could be wrong or could point me to a
tutorial that deals with this.
Cheers
Keith
