iPhone应用程序中的核心数据错误。 “ _OBJC_CLASS _ $ _ NSFetchedResultsController”

Question

"_OBJC_CLASS_$_NSFetchedResultsController", referenced from: objc-class-ref-to-NSFetchedResultsController in RootViewController.o

I'm getting 7 of the errors above in my iphone app. I had an app that used core data but i wanted to use an rss xml parser with it, so i created a new empty app and put both of the projects into it, now i have 7 errors all the same as above!? Any ideas?

确保已将CoreData Framework添加到项目中。
