UITableViewCell и UITableView

Question

У меня есть этот класс ячеек (ModelPortrait2TableViewCell.h):

@interface ModelPortrait2TableViewCell : UITableViewCell
{
    UILabel *imageLabel;
    UILabel *imageLabel2;
    UIButton *boton;
    UIButton *boton2;
}

@property (nonatomic, retain)  UILabel *imageLabel;
@property (nonatomic, retain)  UILabel *imageLabel2;
@property (nonatomic, retain)  UIButton *boton;
@property (nonatomic, retain)  UIButton *boton2;

+ (id)cell;

ModelPortrait2TableViewCell.m

@synthesize imageLabel;
@synthesize imageLabel2;
@synthesize boton;
@synthesize boton2;

+ (id)cell
{
    ModelPortrait2TableViewCell *cell = [[[ModelPortrait2TableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"ModelPortrait2TableViewCell"] autorelease];

    float anchoDefinido = [GlobalData sharedGlobalData].width;
    float altoDefinido = [GlobalData sharedGlobalData].height;

    float spaceX = [GlobalData sharedGlobalData].spaceBetweenImagesPortraitWidth; 
    float spaceY = [GlobalData sharedGlobalData].spaceBetweenImagesPortraitHeight;

     cell.imageLabel = [[[UILabel alloc] initWithFrame:CGRectZero] autorelease];
     [cell.imageLabel setFrame:CGRectMake(spaceX,(altoDefinido-spaceY)+10.0,anchoDefinido,20)];
     [cell.imageLabel setTextAlignment:UITextAlignmentCenter];
     [cell.imageLabel setFont:[UIFont systemFontOfSize:11]];
     [cell.imageLabel setBackgroundColor:[UIColor clearColor]];

     cell.imageLabel2 = [[[UILabel alloc] initWithFrame:CGRectZero] autorelease];
     [cell.imageLabel2 setFrame:CGRectMake((anchoDefinido+spaceX+spaceX),(altoDefinido-spaceY)+10.0,anchoDefinido,20)];
     [cell.imageLabel2 setTextAlignment:UITextAlignmentCenter];
     [cell.imageLabel2 setFont:[UIFont systemFontOfSize:11]];
     [cell.imageLabel2 setBackgroundColor:[UIColor clearColor]];

     cell.boton = [UIButton buttonWithType:UIButtonTypeCustom];
     [cell.boton setFrame: CGRectMake(spaceX,spaceY,anchoDefinido,altoDefinido)]; 
     cell.boton.backgroundColor = [UIColor redColor];

     cell.boton2 = [UIButton buttonWithType:UIButtonTypeCustom];
     [cell.boton2 setFrame: CGRectMake((anchoDefinido+spaceX+spaceX),spaceY,anchoDefinido,altoDefinido)];
     cell.boton2.backgroundColor = [UIColor redColor];

    [cell setSelectionStyle:UITableViewCellSelectionStyleNone]; 

    return cell;
}

Я пытаюсь получить доступ к этой ячейке из моего UITableViewController, но я не могу.

Мой код:

ModelPortrait2TableViewCell *cell;
        cell = [tableView dequeueReusableCellWithIdentifier:@"ModelPortrait2TableViewCell"];

        if (!cell) 
        {
            cell = [ModelPortrait2TableViewCell cell];  
        }


[[cell boton] setFrame:imview.frame];
[[cell boton] setImage:imview.image forState:UIControlStateNormal];
[[cell boton] addTarget:self action:@selector(showInfo:) forControlEvents:UIControlEventTouchUpInside];
[[cell boton] setTitle:[articulo objectForKey:@"Modelo"] forState:UIControlStateNormal];
[[cell boton] setTag:imagen0];
[[cell imageLabel] setText:[articulo objectForKey:@"Modelo"]]; 

или

cell.boton.frame = imview.frame;
[cell.boton setImage:imview.image forState:UIControlStateNormal];
[cell.boton addTarget:self action:@selector(showInfo:) forControlEvents:UIControlEventTouchUpInside];
[cell.boton setTitle:[articulo objectForKey:@"Modelo"] forState:UIControlStateNormal];
[cell.boton setTag:imagen0];
[cell.imageLabel setText:[articulo objectForKey:@"Modelo"]];

Я не могу изменить свою ячейку с моего контроллера ... Любое решение ???
