在Objective C包装器中传递C ++对象

Question

From what I understand you cannot pass c++ objects directly in objectiveC...I think. Instead you have to pass a pointer. Do you have to pass a void pointer and cast it?

For example if I have two C++ objects b2World , and b2Body . If I then create two objective c wrappers World , Body do I then pass b2Body to World with a void pointer and cast it inside World ?

Answer 1

I discovered that I was originally correct. You can pass c++ objects around through void pointers and then cast them.
