Hi all,
I have a Core Data entity that has an attribute called charge (stored
as a float). So I am storing a number of records each of which has a
charge. I simply want to be able to show a running total of charges as
I add or remove items. I was hoping that I might be able to use a
simple binding for this: I created a label and thought I might be able
to bind its value to array controller.arrangedObjects.charge.sum or
something like that. No luck though.
I cannot see anything in the documentation or from searches. Can
anyone point me towards either examples or documentation?
Thanks,
Ian.
