On the Meaning of Life
The Purpose Theory (PT) of the meaning of human life, addressed in the links below, can be considered an objectivist theory. According to PT, God’s creating human beings for a divine purpose is a necessary condition for human life to have objective meaning. Hence, if human life is objectively meaningful, then God exists and created humans for a purpose that he alone formulated.

Arguably, on PT, human meaning is not purely objective. Rather, human meaning is objective in one sense but subjective in another. Human life is objectively meaningful insofar as the source of meaning is completely independent of human attitudes, and thus not subjective in the sense of being wholly relative to the human mind. However, human life is subjectively meaningful in virtue of the fact that human meaning is grounded in God’s purpose, which is entirely subjective to God (i.e., relative to the divine mind) - a point which has raised some interesting objections. For example, would a good God create human beings merely for the sake of fulfilling a purpose that he decided for them? Is that a violation of human autonomy? Would that be to treat human persons as mere means?
In any case, PT should be described as an objectivist view with respect to human attitudes, but as a subjectivist view with respect to the divine mind.
