How can I show a UIDatePicker inside a Popover on iPad using StoryBoard?

Question

I have achieved to show the datepicker inside the popover, doing it programmatically as it is shown in UIDatePicker in UIPopover.

But I have been trying to do it in interface Builder, I already made a View Controller named DatePickerViewController.m with a DatePicker in it and its corresponding IBoulet

#import <UIKit/UIKit.h>

@interface DatePickerViewController : UIViewController
@property (strong, nonatomic) IBOutlet UIDatePicker *birthdayDatePicker;

@end

Then I need this to be shown in a popover when the Birthday text field is being edited. so I use the following code

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField{
    //Assign DatePicker to Birthday TextField
    //build our custom popover view
    DatePickerViewController* popoverContent = [[DatePickerViewController alloc] init];
    //resize the popover view shown
    //in the current view to the view's size
    popoverContent.contentSizeForViewInPopover = CGSizeMake(320, 216);

    // dismiss existing popover
    if (self.popoverControllerBirthday)
    {
        [self.popoverControllerBirthday dismissPopoverAnimated:NO];
        self.popoverControllerBirthday = nil;
    }

    //create a popover controller with my DatePickerViewController in it
    UIPopoverController *popoverControllerForDate = [[UIPopoverController alloc] initWithContentViewController:popoverContent];
    //Set the delegate to self to receive the data of the Datepicker in the popover
    popoverControllerForDate.delegate = self;
    //Adjust the popover Frame to appear where I want
    CGRect myFrame =textField.frame;
    myFrame.origin.x = 260;
    myFrame.origin.y = 320;

    //Present the popover
    [popoverControllerForDate presentPopoverFromRect:myFrame 
                                          inView:self.view 
                        permittedArrowDirections:UIPopoverArrowDirectionDown 
                                        animated:YES];
    self.popoverControllerBirthday = popoverControllerForDate;
    return NO; // tells the textfield not to start its own editing process (ie show the keyboard)

}

And I also import the custom DatePickerViewController in my current ViewController

#import "DatePickerViewController.h"

But it is not showing the datepicker inside the popover.

Does anybody know what could be happening?

You might want to avoid all the work in the storyboard by creating the ViewController and the DatePicker programmatically:

//build our custom popover view
UIView *v = [[UIView alloc] init];
CGRect pickerFrame = CGRectMake(0, 0, 320, 216);
UIDatePicker *pView=[[UIDatePicker alloc] initWithFrame:pickerFrame];
pView.datePickerMode = UIDatePickerModeDate;

self.datePicker = pView;
[v addSubview:self.datePicker];

UIViewController *popoverContent = [[UIViewController alloc]init];
popoverContent.view = v;


//resize the popover view shown
//in the current view to the view's size
popoverContent.contentSizeForViewInPopover = CGSizeMake(320, 216);

// dismiss existing popover
if (self.pcDatePicker)
{
    [self.pcDatePicker dismissPopoverAnimated:NO];
    self.pcDatePicker = nil;
}

//create a popover controller with my DatePickerViewController in it
UIPopoverController *popoverControllerForDate = [[UIPopoverController alloc] initWithContentViewController:popoverContent];

//Set the delegate to self to receive the data of the Datepicker in the popover
popoverControllerForDate.delegate = self;

//Adjust the popover Frame to appear where I want
CGRect myFrame = sender.frame;//CGRectMake(SCREEN_WIDTH / 2, SCREEN_HEIGHT / 2, 320,     200);
myFrame.origin.x = 260;
myFrame.origin.y = 320;

//Present the popover
[popoverControllerForDate presentPopoverFromRect:myFrame
                                          inView:self.view
                        permittedArrowDirections:UIPopoverArrowDirectionAny
                                        animated:YES];

self.pcDatePicker = popoverControllerForDate;

And then use the delegate Method to get the date:

- (void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController
{
    self.startDate = self.datePicker.date;
}

Solved

All I have to do is instantiate the StoryBoard Date Picker View Controller like :

...
DatePickerViewController* popoverContent = [[DatePickerViewController alloc] init];

popoverContent =[[UIStoryboard storyboardWithName:@"MainStoryboard"
                                         bundle:nil]
               instantiateViewControllerWithIdentifier:@"DatePickerVC"];
//resize the popover view shown
//in the current view to the view's size
popoverContent.contentSizeForViewInPopover = CGSizeMake(320, 216);
...

where the identifier is set in StoryBoard Attributes Inspector

and now it is shown
