Accessing a property defined in the class extension from a category, in Objective-C: is it possible?

Question

One of my classes MyClass is very big and I want to split it into several categories MyClass(A), MyClass(B), ... . My problem is that some of the methods of MyClass+A make use of a @property defined in the class extension MyClass().

• Can I access it from the category, and if yes: how?

• If no, is there another way to proceed?

Answer 1

Can I access it from the category, and if yes: how?

Yes. Either:

1. define the continuation category in a different .h file (xxx_Private.h) and include that into your implementation files
2. Or, redefine the method in a category interface at the top of the implementation file.

Option 1 is the better solution.
