Displaying a UIDatePicker inside of a UIPopover - iphone

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];
}

Answer 1

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];
