How to ignore certain PCH defines in some classes? (Cannot find interface declaration for)

For example, I created a category UILabel+AALabel.h

And has added it into PCH: #import "UILabel+AALabel.h"

But this obviously causes an error in my category file (UILabel+AALabel.h), because it attempts to import itself: "Cannot find interface declaration for 'UILabel'".

Is there any way to keep using PCH on a project-level, without having such issues? Maybe there are directives which check the file to which its (pch) contents are imported?

Thanks.

Have you included `#import ` in your category header? – Steve Wilford Oct 27 '15 at 10:49
Don't put it in the PCH file, it's lazy, put it where you actually need it. – Wain Oct 27 '15 at 10:54
Yes, I included and I need it for optimizing – Андрей Бронников Oct 27 '15 at 11:10
