Custom tableViewCell displays incorrectly when scrolled

I have a tableview populated with an array of names and images. I’ve added a custom cell by subclassing UITableViewCell. The custom cell contains a UIImage that has the mode set to “Aspect Fill” and the height and width set to 52 to fit neatly into my custom cell. When I run the application it loads all the images and correctly fits them into my container view at the dimensions I’ve specified. The problem is whenever I scroll the view, the reused cells displays the images as if I did not have a custom cell. In other words, incorrectly. Here is my cellForRowAtIndexPath method

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    static NSString *cellIdentifier = @"Cell";
    customCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
    contact = contactsArray[indexPath.row];
    NSString *firstName = contact[@"mutableFirstName"];
    NSString *lastName = contact[@"mutableLastName"];
    UIImage *image = contact[@"mutableImage"];
    cell.imageView.image = image;
    cell.firstNameLabel.text = firstName;
    cell.lastNameLabel.text = lastName;
    return cell;
}

What if, if your customCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; returns nil ...???

Modify your implementation as :

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    static NSString *CellIdentifier = @"Cell";

    customCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if(cell == nil) {
        cell = [[customCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        cell.backgroundColor = [UIColor clearColor];
    }

    cell.imageView.image = image;
    cell.firstNameLabel.text = [NSString stringWithFormat:@"%@", contact[@"mutableFirstName"]];
    cell.lastNameLabel.text = [NSString stringWithFormat:@"%@", contact[@"mutableImage"]];
    return cell;
}

Hope that helps.
