It has an additional meaning, although the actual implementation of that meaning is not different from the C use case. In Objective-C, not only members of struct pointers can be accessed usig this operator, but instance variables too. However, since the Objective-C runtime is implemented in C, objects are just struct pointers, and ivar manipulation is just structure field manipulation.
