Right. So something like this then:
#import <Foundation/Foundation.h>
@class NSCFArray;
void logIfCFArray (id p)
{
if ([p class] == [NSCFArray class])
NSLog (@"Object is NSCFArray\n");
}
int main (int argc, char *argv[])
{
NSArray *a = [[NSArray alloc] init];
CFArrayRef b = CFArrayCreate (NULL, NULL, 0, &kCFTypeArrayCallBacks);
logIfCFArray ((id)a);
logIfCFArray ((id)b);
return 0;
}
But that doesn't seem to work. It produces:
2009-04-03 11:49:52.032 test[84218:10b] Object is NSCFArray
2009-04-03 11:49:52.034 test[84218:10b] Object is NSCFArray
So, I'm still confused.
Regards,
Chris
