How to add checkboxes to UITableViewCell??

Make a unchecked and checked image..

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {    static NSString *CellIdentifier = @"Cell";    UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];    if (cell == nil) {        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];    }    if ([selectedRowsArray containsObject:[contentArray objectAtIndex:indexPath.row]]) {        cell.imageView.image = [UIImage imageNamed:@"checked.png"];    }    else {       cell.imageView.image = [UIImage imageNamed:@"unchecked.png"];    }    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleChecking:)];    [cell.imageView addGestureRecognizer:tap];    cell.imageView.userInteractionEnabled = YES; //added based on @John 's comment    //[tap release];    cell.textLabel.text = [contentArray objectAtIndex:indexPath.row];    return cell;}- (void) handleChecking:(UITapGestureRecognizer *)tapRecognizer {    CGPoint tapLocation = [tapRecognizer locationInView:self.tableView];    NSIndexPath *tappedIndexPath = [self.tableView indexPathForRowAtPoint:tapLocation];    if ([selectedRowsArray containsObject:[contentArray objectAtIndex:tappedIndexPath.row]]) {        [selectedRowsArray removeObject:[contentArray objectAtIndex:tappedIndexPath.row]];    }    else {        [selectedRowsArray addObject:[contentArray objectAtIndex:tappedIndexPath.row]];    }    [self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:tappedIndexPath] withRowAnimation: UITableViewRowAnimationFade];}

One of the way I can think of is you do custom UITableViewCell (this tutorial is good for starting. This is another, similar one). Inside the custom UITableViewCell you need to put a UIButton there with a circle image. When user select the button, you change the image to the green circle
