UITableViewCell(s) with default image overwritten with other images upon scrolling

Question

Oops,I am facing an issue with table view cells having no image,i.e. the cell with default image.Upon scrolling the default image disappears and some image from a cell is appearing on it.I have implemented the suggestion from Mr.Rckoenes here .Even then I was unable to fix the issue.Here is my implementation code for understanding:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{    
    ReminderClass *reminderToDisplay = [self.remindersArray objectAtIndex:indexPath.row];

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:kCellIdentifier];

    // Now create the cell to display the data
    if (cell == nil) 
    {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:kCellIdentifier] autorelease];
        cell.textLabel.lineBreakMode = UILineBreakModeWordWrap;
        cell.textLabel.numberOfLines = 0;
        cell.textLabel.font = [UIFont fontWithName:kHelvetica size:17.0];
        cell.textLabel.adjustsFontSizeToFitWidth = YES;
        cell.backgroundColor = [UIColor clearColor];
    }

    ......

    if (Image != nil) 
    {
        UIImageView *imageView=[[UIImageView alloc] initWithFrame:CGRectMake(240, 3, 70, 63)];
        imageView.backgroundColor=[UIColor clearColor];
        [imageView setImage:Image];
        cell.accessoryView = imageView;
        [imageView release];
    }
    else
    {
        UIImageView *imageView=[[UIImageView alloc] initWithFrame:CGRectMake(240, 3, 70, 63)];
        imageView.backgroundColor=[UIColor clearColor];
        UIImage *defaultImage = [UIImage imageNamed:kDefaultImage];
        [imageView setImage:defaultImage];
        cell.accessoryView = imageView;
        [imageView release];
    }
    cell.textLabel.text = reminderDetailsString;
    return cell;
}

Can any one please help me,thanks in advance :)

Answer 1

just set dequeueReusableCellWithIdentifier to nil and also reuseIdentifier to nil like bellow..

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:nil];

and

cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil] autorelease];

and also add your other code in this if (cell == nil) if condition..

UPDATE:

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    NSString *CellIdentifier = [NSString stringWithFormat:@"Cell%d%d",indexPath.section,indexPath.row]; 
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease];
        cell.textLabel.lineBreakMode = UILineBreakModeWordWrap;
        cell.textLabel.numberOfLines = 0;
        cell.textLabel.font = [UIFont fontWithName:kHelvetica size:17.0];
        cell.textLabel.adjustsFontSizeToFitWidth = YES;
        cell.backgroundColor = [UIColor clearColor];

        tableView.backgroundColor = [UIColor clearColor];

    NSString *dateString = [dateFormat stringFromDate:reminderDate];

    NSString *valueString = [NSString stringWithFormat:kNameEvent,reminderToDisplay.Name,reminderToDisplay.Event];
    NSString *onString = [NSString stringWithFormat:kOn,dateString];

        self.contactName = [firstName stringByAppendingString:lastName];

        //Now check whether the contact name is same as your reminderToDisplay.Name
        if([reminderToDisplay.Name isEqualToString:contactName] && ABPersonHasImageData(person))
        {
