Reuse Custom Cell using NIB

Question

Hi I'm new to IOS developement and I created a UITableView which uses custom cells that are created in a nib. Below is my code from my ViewController that is loading the cells however if I scroll up and down 3 times the app crashes because I don't think I'm reusing the cells correctly. I googled around but much of the code/solutions I found seemed to be outdated. My code is below any help is greatly appreciated!

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"CustomCell";
    CustomCell *cell = (CustomCell *) [tableView dequeueReusableCellWithIdentifier:@"cellIdentifier"];
    if (cell == nil) {
        NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil];
        for (id currentObject in topLevelObjects){
            if ([currentObject isKindOfClass:[UITableViewCell class]]){
                cell =  (CustomCell *) currentObject;
                break;
            }
        }
    }
    cell.TITLE.text = [NSString stringWithFormat:@"\"%@\"", [TITLE objectAtIndex:indexPath.row]];
    cell.desc.text = [desc objectAtIndex:indexPath.row];
    cell.votes.text = [votes objectAtIndex:indexPath.row];
    return cell;
}

change the row

CustomCell *cell = (CustomCell *) [tableView dequeueReusableCellWithIdentifier:@"cellIdentifier"];  

to be

CustomCell *cell = (CustomCell *) [tableView dequeueReusableCellWithIdentifier: CellIdentifier];  

Go to your CustomCell .xib file in IB, look for the identifier field and set it to CustomCell
