I am building a RSS feed on a tableview. When i run the app, on my iPhone could run smoothly while in ipad, it crashed and showed "Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'Could not instantiate class named UIRefreshControl'"
I tried to run the app on my ipad simulator, it also could run smoothly. May I know what is the problem for that?
Thanks
