我试图从Popover中的按钮中解除UIPopoverViewControler.另外我希望它将数据传回主视图.我有一个modalViewController但不适用于Popover.有谁知道我怎么能做到这一点？

//酥料饼

- (IBAction) save:(id)sender
{
    if ([self startDateIsValid] && [self endDateIsValid]) 
    {

        [[self parentViewController] setDatesForEvent:startDate eventEndDate:endDate allDay:[allDaySwitch isOn]];
        [self dismissModalViewControllerAnimated:YES];

    }

}

// AddEventViewController_iPad

#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#import "dateViewPopOverViewController_iPad.h"
@interface AddEventViewController_iPad : UIViewController <UITableViewDelegate,UITableViewDataSource, MFMailComposeViewControllerDelegate, UITextFieldDelegate,  UIAlertViewDelegate,UIPopoverControllerDelegate,UINavigationControllerDelegate,UIPopoverControllerDelegate,ABPeoplePickerNavigationControllerDelegate, ABNewPersonViewControllerDelegate,DismissPopoverDelegate> {

// datePopover

#import <UIKit/UIKit.h>
#import "AddEventViewController_iPad.h"
@protocol DismissPopoverDelegate <NSObject>

- (void) dismissWithData:(NSString *)data;

@end

@interface dateViewPopOverViewController_iPad : UIViewController<UIPopoverControllerDelegate> {
