After adding Appirater to my iOS project, when I compile, I get the error:
Undefined symbols for architecture i386: \"_OBJC_CLASS_$_Appirater\", referenced
It seems that you haven't properly added the Appirater code to your project. Both Appirater.h and Appirater.m must be part of your project, and Appirater.m must be compiled like all your other files.
Appirater.h
Appirater.m
