objective c - Imports in and iOS Today Extension not working -

i'm trying import libraries today extension (working fine in main app). when run app, errors:

undefined symbols architecture i386: "_objc_class_$_budget", referenced from: objc-class-ref in todayviewcontroller.o "_objc_class_$_jbbarchartview", referenced from: objc-class-ref in todayviewcontroller.o "_objc_class_$_users", referenced from: objc-class-ref in todayviewcontroller.o ld: symbol(s) not found architecture i386 clang: error: linker command failed exit code 1 (use -v see invocation)

here imports:

#import "jbbarchartview.h" #import "jbchartview.h" #import "users.h" #import "budget.h"

any suggestions?
