Local variables default to strong or weak?

Question

Lets say I have local variable(not property) Obj *x = d, is d's reference count incremented? Or is it default a weak reference?

Answer 1

Apple's documentation (Variable Qualifiers section) said:

__strong is the default. An object remains “alive” as long as there is a strong pointer to it.
