Displaying a UIDatePicker inside of a UIPopover

Question

I'm using the following code to display a UIDatePicker within a UIPopover that is displayed when a user clicks a UIButton.

The problem is, it is being displayed in an awkward position and I want to add a UIToolBar above the datePicker where there is extra space. This will have cancel and done button. How can I accomplish this? The button that it is displayed from is the Date of Birth one.

- (IBAction)dateOfBirthButtonPressed:(id)sender{
    UIViewController* popoverContent = [[UIViewController alloc] init];

    UIView *popoverView = [[UIView alloc] init];
    popoverView.backgroundColor = [UIColor blackColor];

    UIDatePicker *datePicker=[[UIDatePicker alloc]init];
    datePicker.frame=CGRectMake(0,44,320, 216);
    datePicker.datePickerMode = UIDatePickerModeDateAndTime;
    [datePicker setMinuteInterval:5];
    [datePicker setTag:10];
//    [datePicker addTarget:self action:@selector(dateChanged) forControlEvents:UIControlEventValueChanged];
    [popoverView addSubview:datePicker];

    popoverContent.view = popoverView;
    UIPopoverController *popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent];
    popoverController.delegate=self;
    [popoverContent release];

    [popoverController setPopoverContentSize:CGSizeMake(320, 264) animated:NO];
    [popoverController presentPopoverFromRect:self.dateOfBirthButton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}

Is there a reason you couldn't just use a UIToolbar?

UIToolbar* toolbar = [[UIToolbar alloc] initWithFrame: CGRectMake(0.0, 0.0, 320.0, 44.0)];
UIBarButtonItem* cancelButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem: UIBarButtonSystemItemCancel
                                                                              target: self
                                                                              action: @selector(cancel)];
UIBarButtonItem* space = [[UIBarButtonItem alloc] initWithBarButtonSystemItem: UIBarButtonSystemItemFlexibleSpace
                                                                       target: nil
                                                                       action: nil];
UIBarButtonItem* doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem: UIBarButtonSystemItemDone
                                                                            target: self
                                                                            action: @selector(done)];

NSMutableArray* toolbarItems = [NSMutableArray array];
[toolbarItems addObject:cancelButton];
[toolbarItems addObject:space];
[toolbarItems addObject:doneButton];
[cancelButton release];
[doneButton release];
[space release];
toolbar.items = toolbarItems;

Then just add the toolbar to your view. Make sure to size it correctly and implement the done and cancel selectors.

[popoverController presentPopoverFromRect:self.dateOfBirthButton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

Use sender in place of self.view

[popoverController presentPopoverFromRect:((UIButton *)sender).bounds inView:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
