I spend 2 hours to solve this problem:

It's working for me

//  GenreDataSource.h

#import Foundation/Foundation.h

    @interface GenreDataSource : NSObject  {
        NSArray *dataSource;
        CGSize cellSize;
    }

@property(nonatomic, assign) CGSize cellSize;

@end



//  GenreDataSource.m
#import "GenreDataSource.h"

@implementation GenreDataSource
@synthesize cellSize;

-(id)init{

    self = [super init];
    if ( self != nil ) {

        dataSource = [[NSArray alloc] initWithObjects:@"All",@"Folk",@"Disco",@"Blues",@"Rock",@"Dance",@"Hip-Hop",@"R&B",@"Soul",@"Lounge",@"Techno",@"Bubstep", nil];
    }
    return self;
}

#pragma mark - UITableViewDataSource

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    return [dataSource count];
}

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

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {

        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero] autorelease];
        [cell setSelectionStyle:UITableViewCellSelectionStyleGray];

        //сконфигурируем структуру
        FontLabel *fLabel= [[FontLabel alloc] initWithFrame:CGRectMake(30, 
                                                                       5, 
                                                                       cellSize.width-30, 
                                                                       cellSize.height-5)
                                                   fontName:@"HelveticaNeueCondensedBlack" 
                                                  pointSize:18.0f];
        [fLabel setTextColor:[UIColor darkTextColor]];
        [fLabel setTag:101];
        [fLabel setBackgroundColor:[UIColor clearColor]];
        [cell.contentView addSubview:fLabel];
        [fLabel release];
    }

    FontLabel *fLabel = (FontLabel*)[cell viewWithTag:101];
    [fLabel setText:[dataSource objectAtIndex:indexPath.row]];

    return cell;
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
    return 1;
}
