objective-c - ABPersonViewController 完成编辑通知

Question

根据 Apple 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完成编辑或已关闭，以便我可以更新我的数据存储中的一些缓存值。

Apple 的文档建议远 ionic 类化 ABPersonViewController。非常感谢任何建议!

Answer 1

    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(delegate)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;     
}

如果您不喜欢“后退按钮”方法 - 您可以将代码直接写入 personViewController shouldPerformDefaultActionForPerson:
