How to go back two viewControllers before, from ABPeoplepicker delegate method - objective-c

Question

I'm developing an app which uses ABPeopleViewController, and i want to when the user finalized choosing a contact, go backward two viewcontroller before.
Here's how i am arriving to ABPeoplePickerNavigationController:
Tap in a button of a main view controller --> load modal (dialog) view controller --> tap in a button of the modal view controller --> load ABContacts.
I'm implementing the delegate of ABContacts in the modal view, which in turn has a delegate in the main view controller.
I want to go back from ABPeoplePicker delegate method to the main view controller.
Hope this understands and someone can help me, i didn't find anything like this.
My MainViewController.h:
#protocol ModalViewDialogDelegate
- (void)didReceiveMail:(NSString *)mail;
#end
#interface SetUpViewController : UIViewController<UITextFieldDelegate, ModalViewDialogDelegate>{
}
//...
My MainViewController.m:
//...
- (void)didReceiveMail:(NSString *)mail{
[self.presentedViewController dismissViewControllerAnimated:YES completion:nil];
//...
My ModalView.h:
#import <AddressBook/AddressBook.h>
#import <AddressBookUI/AddressBookUI.h>
#protocol ModalViewDialogDelegate;
#interface DialogViewController : UIViewController<ABNewPersonViewControllerDelegate, ABPeoplePickerNavigationControllerDelegate>{
id<ModalViewDialogDelegate> delegate;
}
#property (nonatomic, assign) id<ModalViewDialogDelegate> delegate;
#property (nonatomic, retain) NSString * mailSelected;
//...
My modalView.m:
- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier{
//...here i get the email person property and then i want to go backwards to the main view controller, not the modal.
[self dismissViewControllerAnimated:YES completion:nil];
//don't know if it's ok like this, because in the implementation also dismiss presented viewcontroller.
[_delegate didReceiveMail:self.mailSelected];
return NO;
}
return YES;
}

Answer 1

Try putting this
[_delegate didReceiveMail:self.mailSelected];
inside the completion block of the
[self dismissViewControllerAnimated:YES completion:nil];
that precedes it.
(If that doesnt work you can simply call the dissmiss twice on your maincontroller delegate method, each dismiss will remove one from the stack)

Answer 2

[[[self presentingViewController] presentingViewController] dismissViewControllerAnimated:NO completion:nil];
