That selector is a unique index that points to a method of a specific class.
Methods themselves belong to a specific class and can't operate outside of
their classes. (They compile down to regular C functions that accept an
additional object parameter.)
So, it doesn't make sense to use one class's selector on another class.
Maybe these two classes should inherit from a common parent that has the
method you want to share.
