Return custom cell from cellForRowAtIndexPath:

I have a problem and am looking for help.

I need to store an identifier in a cell, so I subclassed UITableViewCell and added an identifier property to it. In my opinion I create cells as follows:

- (SidebarCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell* tableViewCell = [super tableView:tableView cellForRowAtIndexPath:indexPath];
    SidebarCell * cell = (SidebarCell *)tableViewCell;
    Category *category = [categoryDataController.categories objectAtIndex:indexPath.row];
    cell.textLabel.text = category.name;

    if (category.checked == 1) {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
    } else {
        cell.accessoryType = UITableViewCellAccessoryNone;
    }

    return cell;
}

The problem is that when I select one of the cells, the cellForRowAtIndexPath method: instead returns a UTableViewCell SidebarCell object, so I don't have access to the identifier property:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView deselectRowAtIndexPath:[tableView indexPathForSelectedRow] animated:NO];
    SidebarCell *cell = (SidebarCell *)[tableView cellForRowAtIndexPath:indexPath]; // Trying to cast from UITableViewCell to SidebarCell

    if (cell.accessoryType == UITableViewCellAccessoryNone) {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
        [CategoryDataController updateRow:cell.identifier status:1]; // Here the app crashes
    } else if (cell.accessoryType == UITableViewCellAccessoryCheckmark) {
        cell.accessoryType = UITableViewCellAccessoryNone;
        [CategoryDataController updateRow:cell.identifier status:0];
    }    
}

Is there a way for cellForRowAtIndexPath: to return a Sidebarcell object?

Thanks in advance.

Edit

SidebarCell.h

#import <UIKit/UIKit.h>

@interface SidebarCell : UITableViewCell

@property (nonatomic) NSInteger identifier;

@end

SidebarCell.m:

#import "SidebarCell.h"

@implementation SidebarCell

@synthesize identifier;

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    return self;
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state
}

@end

In my case, I used a custom cell of the tempTableViewcell class

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSString *identifier = @"cellidentifier";

    tempTableViewcell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];

    if (cell == nil) {
        cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
    }

    cell.textLabel.text = @"abc";
    return cell;
}
