如何从ABPeoplepicker委托方法之前返回两个viewControllers

我正在开发一个应用程序，它使用ABPeopleViewController，并且我想当用户敲定选择联系人时，向后退回两个viewcontroller。以下是我如何到达ABPeoplePickerNavigationController：点击主视图控制器的按钮 - >加载模态（对话框）视图控制器 - >点击模态视图控制器的按钮 - >加载ABContacts。如何从ABPeoplepicker委托方法之前返回两个viewControllers

我在模态视图中实现了ABContacts的委托，而该模态视图又在主视图控制器中有一个委托。

我想从ABPeoplePicker委托方法返回到主视图控制器。

希望这理解，有人可以帮助我，我没有发现这样的事情。

我MainViewController.h：

@protocol ModalViewDialogDelegate 

- (void)didReceiveMail:(NSString *)mail; 

@end 

@interface SetUpViewController : UIViewController<UITextFieldDelegate, ModalViewDialogDelegate>{ 
} 
//...

我MainViewController.m：

//... 
    - (void)didReceiveMail:(NSString *)mail{ 

    [self.presentedViewController dismissViewControllerAnimated:YES completion:nil]; 
    //...

我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; 
//...

我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; 
}

尝试把这个

[_delegate didReceiveMail:self.mailSelected];

的

[self dismissViewControllerAnimated:YES completion:nil];

它之前完成块内。

（如果不工作，你可以简单地调用dissmiss两次对你maincontroller委托方法，每个驳回将从堆栈中删除一个）

非常感谢您！它通过在委托方法中调用dismissModalViewController两次来工作！ – sheinix 2012-07-20 02:03:35

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