Проблема в DatePicker и оповещении

Question

Я использую UIDATEPICKER.Проблема в том, что когда я нажимаю на кнопку, появляется лист предупреждения, и средство выбора даты добавляется как подпредставление, но я хочу две кнопки,

1-отмена 2-сделано

что я буду делать?

UIActionSheet * aac = [[UIActionSheet alloc] initWithTitle: @ "Сколько?"делегат: self cancelButtonTitle: nil destructiveButtonTitle: nil otherButtonTitles: nil];

aac.actionSheetStyle = UIActionSheetStyleBlackOpaque;

sheet = aac;
UIDatePicker *theDatePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0.0, 44.0, 0.0, 0.0)];
if(IsDateSelected==YES)
{
    theDatePicker.datePickerMode = UIDatePickerModeDate;
    theDatePicker.maximumDate=[NSDate date];
}else {
    theDatePicker.datePickerMode = UIDatePickerModeTime;
}

self.dtpicker = theDatePicker;
[theDatePicker release];
[dtpicker addTarget:self action:@selector(dateChanged) forControlEvents:UIControlEventValueChanged];

pickerDateToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
pickerDateToolbar.barStyle = UIBarStyleBlackOpaque;
[pickerDateToolbar sizeToFit];

NSMutableArray *barItems = [[NSMutableArray alloc] init];

UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:self action:nil];
[barItems addObject:flexSpace];

UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(DatePickerCancelClick)];
[barItems addObject:cancelBtn];

//// это не работает .. Я хочу это ....

что будетя делаю?

UIDatePicker появляется после нажатия кнопки UIB
