Sprite-kit: removeFromParent when parent gone

Question

Is it safe to call [n removeFromParent]; after the parent to n has been released (and thus does not exist)?

I guess n.parent will be nil at that point.

Do I have to do something like

if (n.parent != nil)
  [n removeFromParent];

Yes, I do it all the time. If you want to validate, simply do something like this the next time you call want to do it.

[n removeFromParent];
[n removeFromParent];
[n removeFromParent];
[n removeFromParent];

You'll notice no side effects.
