Question

我的应用需要将自定义类的实例与iPhone的AddressBook中的联系人记录相关联。当我呈现 ABPeoplePickerNavigationController 并允许用户选择现有的联系人时，一切都很好。问题是没有明显的方法允许用户轻松添加联系人记录，如果他们正在寻找的联系人记录已经存在于他们的地址簿中。

人们如何以轻松的方式从 ABPeoplePickerNavigationController 转到 ABNewPersonViewController 对用户来说直观吗？

Answer 1

您可以创建一个UIBarButton并将其添加到ABPeoplePickerNavigationController的UINavigationBar中。

    peoplePicker.topViewController.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addPerson:)];

-(IBAction)addPerson:(id)sender{
    ABNewPersonViewController *view = [[ABNewPersonViewController alloc] init];
    view.newPersonViewDelegate = self;
    UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:view];
    [self.picker presentModalViewController:nc animated:YES];
}

我遇到的问题是ABPeoplePickerNavigationController有一个取消按钮放在rightBarButtonItem插槽中，我不得不更新

上的导航栏

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated{

我已使用blog在我的worked example上记录了整个过程，该过程应该允许您创建类似于iPhone上的联系人样式应用程序。希望这会有所帮助。

我发现Scott Sherwood的方法以及他在他的网站上发布的演示非常有帮助。作为他博客上提到的评论者之一，编辑模式中的取消按钮存在问题。

我刚刚提出修复Scott的演示，以及针对Person View Controller的不同方法： http://finalize.com/2013/05/12/using-and-customizing-the-address-book-ui/

我对Person View Controller的建议是在协议方法peoplePickerNavigationController：shouldContinueAfterSelectingPerson：for ABPeoplePickerNavigationControllerDelegate中手动启动它。

// Displays the information of a selected person
- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person
{

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

    view.personViewDelegate = self;
    view.displayedPerson = person; // Assume person is already defined.
    view.allowsEditing = YES;
    view.allowsActions = YES;

    [peoplePicker pushViewController:view animated:YES];

    return NO;
}

这里唯一的问题是编辑后名称的人员选取器表视图不会自动刷新。这可以通过使用通讯簿回调来修复。我将在我发布的GitHub项目中展示如何做到这一点：

似乎无法直接从ABPeoplePickerNavigationController添加新联系人。因此，当用户单击添加按钮时，我将呈现带有两个按钮的UIActionSheet：

- (void) addContact{

    contactMenu = [[UIActionSheet alloc] 
                           initWithTitle: nil 
                           delegate:self
                           cancelButtonTitle:@"Cancel"
                           destructiveButtonTitle: nil
                           otherButtonTitles:@"Select a contact", @"Add a new contact", NULL];

    [contactMenu showInView:self.view];

}

以下是关联的委托方法：

    - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{



        if(buttonIndex == 0){
            // select an existing contact   
            ABPeoplePickerNavigationController *peoplePicker = [[ABPeoplePickerNavigationController alloc] init];
            peoplePicker.peoplePickerDelegate = self;
            [self presentModalViewController:peoplePicker animated:YES];

        }

        if(buttonIndex == 1){

            // add a new contact
            ABNewPersonViewController *newPersonViewController = [[ABNewPersonViewController alloc] init];
            newPersonViewController.newPersonViewDelegate = self;

            UINavigationController *personNavController = [[UINavigationController alloc] initWithRootViewController:newPersonViewController];
            [self presentModalViewController:personNavController animated:YES];

            [personNavController release];
            [newPersonViewController release];

        }

            if(buttonIndex == 2){
        // cancel the operation
        [actionSheet dismissWithClickedButtonIndex:2 animated:YES];
    }


}

如何绕过ABPeoplePickerNavigationController缺少“添加”按钮？
