Right, but the original question was about figuring out what they are
at runtime which I don't believe is possible and it's not clear to me
whether you think it is possible. You seem to be suggesting it might
be. Perhaps you could complete this but of test code:
#import <Foundation/Foundation.h>
void logIfCFArray (const void *p)
{
if (/* some test here */)
NSLog (@"Object is CFArray\n");
}
int main (int argc, char *argv[])
{
NSArray *a = [[NSArray alloc] init];
CFArrayRef b = CFArrayCreate (NULL, NULL, 0, &kCFTypeArrayCallBacks);
logIfCFArray (a);
logIfCFArray (b);
return 0;
}
Regards,
Chris
