> In Tiger that was the best means available, but if you're
targeting Leopard
there is a better option available:
Create your fetch request to fetch all instances of a given entity and
execute the fetch with countForFetchRequest:error: which will simply return
the number of instances/rows that match your query.
Though Steve mentioned off-list that he's targeting Tiger, I had
managed to completely forget about this method - my apologies for the
misinformation.
Well, it's probably best to ask the NSManagedObjectContext
-respondsToSelector:@selector(countForFetchRequest:error:) and use
the slow -executeFetchRequest:error: if the result is NO.
