Okay, I'm thoroughly confused now. What exactly is this hash value? The
documentation just says its "an integer that can be used as a table address in
a
hash table structure." That doesn't mean much to me.
Do the following two objects have the same hash value, and if so, why do thay?
How is it assigned?
id myStr1 = @"8760";
id myStr2 = @"8760";
