    I am updating a TableViewController from entity that contains two strings and one integer. The strings work correctly the integer does not. Here is my code;
     - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
        static NSString *CellIdentifier = @"Cell";
        UsersCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
        if (!cell) {
            cell = [[GolfersCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
        Users *users = [_fetchedResultsController objectAtIndexPath:indexPath];
        cell.firstName.text = users.firstName;
        cell.lastName.text = users.lastName;
            int i = [users.gendID intValue] ;
        cell.genID.text = [NSString stringWithFormat:@"%d", i];
        [self configureCell:cell atIndexPath:indexPath];
        return cell;
    Now this does work, commenting out the line "int i = [users.gendID intValue] ;" and it will work correctly. Stepping though the program this the error that it returns;
     2012-04-30 16:49:02.369 My App [9757:fb03] -[Users gendID]: unrecognized selector sent to instance 0x6b8a6c0

    Thanks for the help

    What type is the gendID property? Post the code from interface Users that shows the @property line for gendID.

    If the Users class doesn't have a gendID property, then that's the problem: you've misspelled the property name. I mention this because the UsersCell class has a genID property, or possibly that's the GolfersCell class, which may or may not have an inheritance relationship with the UsersCell class.

    It's difficult to tell what's going on because you haven't shown any @interfaces for any of your classes. Without seeing types, no one knows what objects you're really talking about. It's like saying your pet is sick, but without saying whether it's a bird, a fish, a dog, or an iguana.

    thanks, I am thinking this is due to lack of sleep.

    There should have been a compiler warning at the misspelled line. If you're ignoring warnings, you're doing it wrong, especially if you're also tired.
