Xcode: Get rid of forward class warning

Question

In Xcode, I have a forward class declared so as to avoid a circular import e.g.

@class MyClass;

And then I do a method call on that class e.g.

[MyClass myMethod];

But I get a forward class warning e.g.

warning: receiver 'MyClass' is a forward class and corresponding @interface may not exist

How can I hide those across my whole project?

Answer 1

have you imported the class in your implementation of class?

Answer 2

You use forward class declarations in your header file to prevent circular imports.

You must still import the MyClass header in your .m file. The circular import problem doesn't exist with .m files.

Answer 3

My answer to a similar question may be of use here.

The basic concept is this:

use @class in header files, and then use #import in the .m files.
