I Used GData to retrieve the Google spread sheet data and i build the application successfully on the simulator .

Question

But when i tried to build it on the device(iphone) it is giving some error . That is i got the error like this : "_OBJC_CLASS_$_GDataServiceGoogleSpreadsheet", referenced from: __objc_classrefs__DATA@0 in spreadsheetViewController.o and

"_kGDataGoogleSpreadsheetsPrivateFullFeed", referenced from: _kGDataGoogleSpreadsheetsPrivateFullFeed$non_lazy_ptr in spreadsheetViewController.o
