Hello,
Thanks to help from this forum I have developed a simple plugin
system that uses a formal protocol. In my main application I am
creating an array of objects of different classes that all implement
the protocol. One pair of methods common to all the objects (and in
the protocol) is name and setName. I want to display the name of
each object in an NsTableView. I approached the problem by creating
an NsArrayController in IB and creating a key for name. In the
inspector I set the object class name to the name of the header file
containing my protocol. I set the bindings in the NsTableView as I
would for a 'regular' NsArrayController. When I fire up the
application I am told that the class is not key value coding
compliant for the key I defined. Is it a problem to use a protocol
file as the object class name? Is there another way to approach
this? Would switching to an informal protocol help?
Thank you,
Ryan
