Hi,
I'm coming across the odd instance where the use of a class variable
would seem to make sense.
I can do this with a static definition in the class implementation
file, I suppose.
Question is: is this particularly frowned upon in the Cocoa world? If
so, why?
Thanks,
--colin
The canonical implementation of a singleton class uses a static to
hold the singleton instance. There are other examples in Apple sample
code of using class statics. So, I would say that it's not frowned
upon as long as there's a good reason to do it.
