UIDatePicker en UIActionSheet en el iPad

Question

En la versión de iPhone de mi aplicación, tengo un UIDatePicker en un UIActionSheet. Aparece correctamente Ahora estoy configurando la versión de iPad de la aplicación, y el mismo UIActionSheet cuando se ve en el iPad aparece como un cuadro en blanco en blanco.

Aquí está el código que estoy utilizando:

UIDatePicker *datePickerView = [[UIDatePicker alloc] init]; 
    datePickerView.datePickerMode = UIDatePickerModeDate; 

    self.dateActionSheet = [[UIActionSheet alloc] initWithTitle:@"Choose a Follow-up Date" 
                delegate:self cancelButtonTitle:nil 
            destructiveButtonTitle:nil otherButtonTitles:@"Done", nil]; 

    [self.dateActionSheet showInView:self.view]; 
    [self.dateActionSheet addSubview:datePickerView]; 
    [self.dateActionSheet sendSubviewToBack:datePickerView]; 
    [self.dateActionSheet setBounds:CGRectMake(0,0,320, 500)]; 

    CGRect pickerRect = datePickerView.bounds; 
    pickerRect.origin.y = -95; 
    datePickerView.bounds = pickerRect;

terminé creando un segmento separado del código para el Popover iPad:

//build our custom popover view 
UIViewController* popoverContent = [[UIViewController alloc] init]; 
UIView* popoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 344)]; 
popoverView.backgroundColor = [UIColor whiteColor]; 

datePicker.frame = CGRectMake(0, 44, 320, 300); 

[popoverView addSubview:toolbar]; 
[popoverView addSubview:datePicker]; 
popoverContent.view = popoverView; 

//resize the popover view shown 
//in the current view to the view's size 
popoverContent.contentSizeForViewInPopover = CGSizeMake(320, 244); 

//create a popover controller 
UIPopoverController *popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent]; 

//present the popover view non-modal with a 
//refrence to the button pressed within the current view 
[popoverController presentPopoverFromBarButtonItem:self.navigationItem.leftBarButtonItem 
          permittedArrowDirections:UIPopoverArrowDirectionAny 
              animated:YES]; 

//release the popover content 
[popoverView release]; 
[popoverContent release];
