Hey I have pasted in some code I wrote a while back to cover this scenario. There are two examples one with an actionsheet and one without an actionsheet:

- (void)textFieldDidBeginEditing:(UITextField *)myTextField{

             [myTextField resignFirstResponder];

             actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil];

             [actionSheet setActionSheetStyle:UIActionSheetStyleBlackTranslucent];

             CGRect pickerFrame = CGRectMake(0, 40, 0, 0);

             UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:pickerFrame];

              pickerView.showsSelectionIndicator = YES;

              pickerView.dataSource = self;

              pickerView.delegate = self;

              [actionSheet addSubview:pickerView];

              [pickerView release]; //NB this may result on the pickerview going black the next time you come back to the textfield, if this is the case just remove this statement

              UISegmentedControl *closeButton = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:NSLocalizedString(@"SUBMIT", @"")]];

              closeButton.momentary = YES;

               closeButton.frame = CGRectMake(260, 7.0f, 50.0f, 30.0f);

               closeButton.segmentedControlStyle = UISegmentedControlStyleBar;

               closeButton.tintColor = [UIColor blackColor];

               [closeButton addTarget:self action:@selector(dismissActionSheet:) forControlEvents:UIControlEventValueChanged];

               [actionSheet addSubview:closeButton];

               [closeButton release];

               [actionSheet showInView:displayedInView];

               [actionSheet setBounds:CGRectMake(0, 0, 320, 485)];

}

This is the code without the actionsheet:

- (void)textFieldDidBeginEditing:(UITextField *)myTextField{

         [myTextField resignFirstResponder];

          for (int component = 0;  component < (((NSInteger)numberOfComponentsForPickerView) - 1); component++) {

              NSInteger valueForRow = [[self.textField.text substringWithRange:NSMakeRange(component,1)] integerValue];

               [pickerView selectRow:valueForRow inComponent:component animated:YES];

          }

           [self fadeInPickerView];

            [view addSubview:pickerView];

            [pickerView release];

}
