Greetings,
I have a Core Data application that uses inheritance of entities. I
have an entity that contains some common attributes, and then a
number of other entities that add their own attributes.
I want to have an uber tableview that contains all of the different
kinds of entities (mainly for overview / debugging). By turning off
the "Raises for not applicable keys", I can have all of the different
objects displayed in the tableview.
The problem I'm having is when there is an attribute that lives in
one entity but not in the other. I get a "Not Applicable" in the
cell, but I'd rather just show an empty cell. These columns have
number formatters, and IB wants an integer value for the placeholder,
so an empty string is not allowed.
I came across setDefaultPlaceholder:forMarker:withBindg:, but I'm not
sure what class I should direct that to (plus there's not a huge
amount of stuff on the web that refers to that)
Is there a way to set the Not Applicable marker in the tableview, or
do I need to use setPlaceholderString: on all of the table cells
involved?
Thanks in advance,
