介绍：

本教程将介绍怎样通过代码从地址簿中获取联系人信息。在iPhone上这实际上比你想象的更容易。你可以提取任何存储于地址簿中的信息，如图片（照片），email地址。注意： iPhone提供了简易的用户联系信息的提取方法但附加了编辑限制。你的程序可以访问所有信息但不允许修改。本教程中，我将介绍提取用户联系信息的简单步骤，最终输出如下所示：

开始

现在开始介绍从地址簿提取联系信息的步骤。
步骤1.建立一个新Xcode项目，取名为 ‘RetrieveContactInfo’。

图1. 建立Xcode项目

图2. 命名你的Xcode项目

步骤 2. 在 ‘Group & File’ 面板打开 ‘Frameworks’。右击任意framework并选择‘Reveal in Finder’ (图 3)。在Finder窗口移到最前面找到‘AddressBook.framework’和 ‘AddressBookUI.framework’。将它们拖入 ‘Frameworks’ 文件夹；不要选取 ‘Copy items into destination group’s folder’。

[peoplePicker dismissModalViewControllerAnimated:YES];

return YES;
}

return NO;
}

- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker
{
// assigning control back to the main controller
[picker dismissModalViewControllerAnimated:YES];
}

5. 打开 ‘RetrieveContactInfoViewController.xib’文件。在视图中加入三个标签和一个按钮。
