here’s the code for my “cellForRowAtIndexPath”

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"AbfahrtszeitResultTableCell";

    AbfahrtszeitResultTableCell *cell = (AbfahrtszeitResultTableCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"AbfahrtszeitResultTableCell" owner:nil options:nil];

        for (id currentObject in topLevelObjects) {
            if ([currentObject isKindOfClass:[UITableViewCell class]]) {
                cell = (AbfahrtszeitResultTableCell *) currentObject;
                break;
            }
        }

        // make cell not-selectable
        cell.selectionStyle = UITableViewCellSelectionStyleNone;

        // background color
        BOOL day = [self isDayView];

        if (day) {
            UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:ABFAHRTSZEIT_RESULT_TABLE_CELL_BACKGROUND_IMAGE_RED]];
            cell.backgroundView = imageView;
            [imageView release];
        } else {
            UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:ABFAHRTSZEIT_RESULT_TABLE_CELL_BACKGROUND_IMAGE_BLUE]];
            cell.backgroundView = imageView;
            [imageView release];
        }

        // text color
        cell.textLabel.textColor = [UIColor whiteColor];
    }

    // Set up the cell...
    AbfahrtszeitResult *result = [abfahrten objectAtIndex:indexPath.row];
    cell.linienLabel.text = [TextUtil cleanUpString:result.linie];
    cell.zielLabel.text = [TextUtil cleanUpString:result.ziel];
    cell.zeitLabel.text = [TextUtil cleanUpString:result.zeit];

    return cell;
}

    You read the stack from the bottom to the top. Here’s the key area:

    12  Foundation                      0x0002cbc6 -[NSPlaceholderMutableString initWithString:] + 78
13  here_my_app                     0x0002c35e 0x1000 + 176990
14  here_my_app                     0x00029a6c 0x1000 + 166508
15  UIKit                           0x000a9248 -[UITableView(UITableViewInternal) _createPreparedCellForGlobalRow:withIndexPath:] + 644

    It looks like 15 is UIKit trying to create cells for a UITableView. 13 and 14 are in your code, likely your tableView:cellForRowAtIndexPath: method. 12 is a Foundation method dealing with strings.

    I would take a look at your tableView:cellForRowAtIndexPath: method and see what you could be doing wrong with string initialization or post your method for us to examine.
