title: Imports in and iOS Today Extension not working
body: <p>I'm trying to import some libraries into a today extension (working fine in the main app). When I run the app, I get the errors:</p>
  
  <pre><code>Undefined symbols for 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 for architecture i386
  clang: error: linker command failed with exit code 1 (use -v to see invocation)
  </code></pre>
  
  <p>Here are the imports:</p>
  
  <pre><code>#import "JBBarChartView.h"
  #import "JBChartView.h"
  #import "Users.h"
  #import "Budget.h"
  </code></pre>
  
  <p>Any suggestions?</p>
