Question

I’m having some error on the following relationship

I have 2 classes, Class A and Class B
inside Class A header, it will #import “B.h”
inside Class B header, it will #import “A.h”

I’m having error during compilation. Anyone know how can I resolve this?

Error looks something like this:
expected specifier-qualifier-list before ‘GameUILayer’

Answer 1

Instead of importing the headers in the .h files, use forward declarations. So instead of

#import "ClassA.h"

you use:

@class ClassA

etc

and then you use the import statement within the .m files.

See my earlier answer for the link to the documenation.
