Undefined symbols for architecture i386 “_OBJC_CLASS_$_Appirater”

Question

After adding Appirater to my iOS project, when I compile, I get the error:

Undefined symbols for architecture i386:
  \"_OBJC_CLASS_$_Appirater\", referenced         


        

Answer 1

I just had the same problem, and fixed it.

The cause of my issue is I had dragged and dropped a file from other project to the current.

Of course it is working when we remove and recreate the file.
