Jonathan,
Thanks for your reply. The cast would of course work, but seems icky
since the variable is not an NSArray, it could be an NSSet,
NSDictionary, etc. The snippit I gave is of course an example, but the
real code is in an NSValueTransformer subclass' "-(id)transformedValue:
(id)value" method, hence my use of 'id'.
I guess my real question is: are people using -Wstrict-selector-match or
do most of you run into annoying warnings like below?
Cheers,
Sean
