Hi all, I'm having trouble figuring this out.
I have a logging function thus:
void GCLogObjCMethod( id obj, SEL selector, NSUInteger lineNumber,
NSString* tag, NSString* format, ... );
I'd like to be able to wrap this using a macro that automatically supplies the
object, selector, line number and 'tag' (which is usually the class name of the
object) and leaves only the format and the variable arguments to be supplied. I
haven't been able to come up with a way that works. Can it be done? i.e. what I
want is a macro:
GCLOGOC( @"this is a format string: %@, with any number of params: %@", paramA,
paramB );
and this expands to:
GCLogObjCMethod( self, _cmd, __LINE__, NSStringFromClass([self class]), @"this
is a format string: %@, with any number of params: %@", paramA, paramB );
(or expands to nothing at all if logging has been turned off).
How can I define the macro so it can handle the variable parameter list?
