Do I have to release this variable?

UIViewController *parentController;
for (UIView* next = [self superview]; next; next = next.superview) {
    UIResponder* nextResponder = [next nextResponder];
    if ([nextResponder isKindOfClass:[UIViewController class]]) {
        parentController = (UIViewController*)nextResponder;
    }
}

In this code, do I have to release the parentController? Then, when?

You don't have release it because you haven't increase it's retain count (by new, alloc, retain or copy).

As you didn't take the ownership(retain/alloc/copy/new) of parentController object so you don't have to release it.

No. You are not taking ownership, so no need to release it either.
