ABPersonViewController已完成编辑通知

Question

按照苹果公司的快速联系人示例代码使用ABPersonViewController。

ABRecordRef person = (ABRecordRef)[people objectAtIndex:0];
    ABPersonViewController *picker = [[[ABPersonViewController alloc] init] autorelease];
    picker.personViewDelegate = self;
    picker.displayedPerson = person;
    picker.allowsEditing = YES;
    [self.navigationController pushViewController:picker animated:YES];

我需要一种方式来通知选择器已经完成编辑或者已经关闭，这样我就可以更新我的数据存储中的一些缓存值。

苹果的文档建议远离ABPersonViewController的子类化。任何建议都是非常感谢的！

    ABPersonViewController *personViewController = [[ABPersonViewController alloc] init];

        personViewController.personViewDelegate = self;
        personViewController.displayedPerson = person; 
        personViewController.allowsEditing=YES;
        personViewController.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Back",nil) style:UIBarButtonItemStylePlain target:self action:@selector(ReturnFromPersonView)] ;
        [self.navigationController pushViewController:personViewController animated:YES];
        [personViewController release];

然后编写您的ReturnFromPersonView方法和委托方法

- (BOOL)personViewController:(ABPersonViewController *)personViewController shouldPerformDefaultActionForPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifierForValue
{
        // you can write you code here with  [self.navigationController popViewControllerAnimated:YES];
        return YES;     
}

如果你不喜欢“后退按钮”方法--你可以把你的代码直接写进personViewController shouldPerformDefaultActionForPerson：
