.mm is an objective c++ class where you can code for both the languages

Step 4
Now in your ObjCCalls.h class write the following

We have made a static method so that we can directly call the method with class name from HelloWorld class
Step 5
In your ObjCCalls.cpp define the static method

Step 6
now in your HelloWorldScene.cpp class, include the ObjCCalls.h class and make a function and define the function as:

So now you are able to call the objective code from a c++ class
