我想创建一个自定义视图，就像iPhone中的联系人一样。有没有可用于制作自定义视图的教程，就像ABPeoplePickerNavigationController一样？
请注意，我不想打开AddressBookUI框架提供的默认人员选取器控制器。另外，我确实希望将此导航控制器绑定到我的主视图中。
为了参考我想要的东西，你可以在iOS设备上推荐Whatsapp的联系人标签。
编辑：我已经有了一个联系人列表，并在表格视图中显示了人员的姓名。现在，我想从A-Z创建一个字母索引，并在点击该索引时，表视图应该滚动到那些联系人。另外，如何通过他/她的姓或名来实现搜索功能以查找用户？
答案 0 :(得分：3)
我在目前正在构建的应用程序中完全相同，我们也从Whatsapp这样的应用程序中获得了灵感。
我使用了一个简单的桌面视图，其中包含用于视觉效果的自定义单元格，只需使用名称＆amp;图片。
我的流程如下：
contact对象（或另一种保持数据的持久方式）通过ABAddressbook框架，您可以浏览所有联系人，并在新的联系人对象中对其进行转换。在ABPerson对象中保留Contact的引用，这样您以后只需使用引用即可查找和更新您的联系人。如果您不这样做，则每次要更新联系人时都必须浏览所有ABPersons。
你可以直接使用ABPersons，但代码真的很痛苦。
一旦您提取了所有联系人，请确保在使用核心数据时保存上下文，或将其存储在.sqlite中。
This appcoda tutorial是一个适合tableview教程的自定义单元格。你可以通过谷歌搜索找到一千多个＆＃34; tableview定制单元ios＆＃34;并找到你可能喜欢的不同的东西。最后，您只需要一个带有标签和图片的单元格，您可以使用我用于＆＃34;联系人＆＃34;的另一个桌面视图的简单UITableViewCell。类型。
使该联系人列表保持最新（获取正确的数字，图片，名称等）并确保它们在更新之前存在，检查联系人是否已被删除，添加等等。所有必须按顺序完成为了让你的清单准确，这是一个非常漫长/烦人的过程。
我可以分享我的Contact类，但它包含了许多不相关的代码，可能会让您感到困惑，因为： - 我还要检查这些联系人是否已经是我的应用的用户，以便在我的桌面视图的特定部分中移动它们 - 我将我的tableview分成27个部分（用户，然后是字母）。
另外，我会用最后一条通用编程建议来阻止它：首先写下你需要的东西和你需要的东西，获得所有的可能性是个好主意。我碰到了许多简单的问题，我花了一段时间才解决，要么是因为我没有正确计划，要么是因为它被隐藏了。
例如：
因为这是非常特定于应用程序的，所以我不会重复我所遇到的每一个问题以及我为此所做的事情，但是你明白了:)尽管我可以随意提出任何非常具体的问题。已经有一个非常具体的解决方案，因为我几乎不得不从头开始复制whatsapp的联系人，而且，我做到了。 （我实际上和Anonymess和iOS完全相同）
编辑：以下是我的ABPerson提取方法的一些方法; ContactDAO主要与我的持久模型（CoreData）进行交互，我相信他们的名字足够清晰，可以让您了解发生了什么。我对评论和变量名感到满意，所以你应该毫不费力地阅读它。这里有一大堆代码。

说到索引，this tutorial应该没问题。

表格视图的方法有助于提供您想要的结果：
- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView
和
- (NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title
