Ok, depois de lutar por um longo tempo com a estúpida visualização de seleção no iOS 4, decidi mudar meu controle para uma tabela simples: aqui está o código:
ComboBoxView.m = which is actually looks more like pickerview.

@synthesize displayedObjects;

if (cell == nil) {

//cell.contentView.frame = CGRectMake(0, 0, 230.0,16);

return cell;
}

Aqui está o arquivo .h para isso:
//
// ComboBoxView.h
// iTrophy
//
// Created by Gal Blank on 8/18/10.
//
#import <UIKit/UIKit.h>
@interface ComboBoxView : UITableViewController {
NSMutableArray *displayedObjects;
}
@property (nonatomic, retain) NSMutableArray *displayedObjects;
@end
now, in the ViewController where I had Apple UIPickerView I replaced with my own ComboBox view and made it size what ever I wish.
ComboBoxView *mypickerholder = [[ComboBoxView alloc] init];
[mypickerholder.view setFrame:CGRectMake(50, 220, 230, 80)];
[mypickerholder setDisplayedObjects:awardTypesArray];
é isso, agora a única coisa que resta é criar uma variável de membro na visão combobox que manterá a seleção de linha atual, e estamos prontos.
Aproveite todos.
