How to retrieve Objective-C variable from C++ method?

Question

I mixed some C++ codes with Objective-C in class with .mm extension.

I synthesized some variables in Objective-C, and I want to retrieve those variables in C++ methods. How to do that?

I tried [self aVariable], this->aVariable to retrieve the synthesized variables, but failed.

Answer 1

You cannot use self in a C++ class. this->aVariable doesn't say anything. It doesn't say whether you are trying to call a method. In fact it doesn't do anything with aVariable.

I assume the method is attached to an objective-C object. If so call it as follows from the C++ class:

[aVariable <method>];

Answer 2

I fixed my problem after reading this post:
