That works fine on 10.7 and later, but on 10.6.x, I get a runtime exception that [NSConcretePointerArray copyWithZone:] is abstract*. NSPointerArray documentation says that it supports NSCopying and is available from 10.5 and later. Was -copy not properly implemented until 10.7? How can I workaround this?
-[NSPointerArray copyWithZone:] was not implemented until 10.7. The alternative is to duplicate the contents of the array manually.
