i may not fully understand your question, but can you not just use NSValue valueWithPointer as your collection keys? or, if a number at all, the number matching the pointer representation: [NSNumber numberWithLong:*(ptrdiff_t*)&pointer] or a string in a similar manner: [NSString stringWithFormat:@"%p", pointer]; in my experience resorting to tricks of objc_getAssociatedObject is asking for trouble (e.g. the associated object is not released with zombies).
