The language forbids passing objects by value. You must pass it by
reference. NSDictionary *, not just NSDictionary.

The language forbids setting a property if you haven't declared one,
either using @property or by declaring a getter/setter pair. It also
forbids setting a property using a pointer declared to be of type
"id". Either one of these could be your problem.
