If I wanted to store an object in a dictionary and set its key as the object's memory address - how would I go about doing this?
I'm racking my brains trying to think of a good reason to do this and am drawing a blank. I can, however, think of myriad bad reasons.
Right now I'm doing this: int i; for (i = 0 ; i < 10 ; i++) { NSObject *myObject = [[NSObject alloc] init];[dictionary setValue:myObject forKey:[NSString stringWithFormat:@"%x", &myObject]];}The above does seem to work, but the memory address that I get always seems to be the same.
myObject is a variable (of type pointer) that is allocated on the stack. Its address is always going to be the same inside that tight loop, since the stack pointer isn't changing.
