デフォルトのアプリからリマインダーを取得しようとしています。

if([eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)]) {
        // need user permission for iOS 6 and later
        [eventStore requestAccessToEntityType:EKEntityTypeReminder completion:^(BOOL granted, NSError *error) {
            if (granted) {
                //---- codes here when user allow your app to access theirs' calendar.
                [self performCalendarActivity:eventStore];
            }
            else {
                //----- codes here when user NOT allow your app to access the calendar.
            }
        }];

次のエラーが表示されます:- カレンダー デーモンへの述語呼び出しに失敗しました: エラー Domain=EKCADErrorDomain Code=1013 "The operation could not be completed. (EKCADErrorDomain error 1013.)"
