仿趣头条获取系统通讯录，并自定义通讯录界面

其他 2018-12-09 00:55:02 阅读次数: 0

我们有个项目 需求要做一个方趣头条的获取通讯录的要求，在此期间，对搜索栏和边栏首字母检索，有些陌生，踩了一些坑。
先来看效果在这里插入图片描述

首先是获取系统通讯录，在iOS9之后，iOS对通讯录的库有了很大的改善。用起来很方便，但是点要注意在引用
#import <ContactsUI/ContactsUI.h>
#import <Contacts/Contacts.h>
这两个库的时候，需要手动添加.framework库如下：在这里插入图片描述
如果不手动添加 会出一个 clang 文件的错

“XLContact.h”

然后我们自定义一个通讯录的model类

这里要注意，我们定义这个model类一方面用来存储联系人，一方面用来定义 contact_name 来让 代码对 联系人按照首字母进行排序

注意这句代码NSArray *sortedPersonArrayForSection = [collation sortedArrayFromArray:personArrayForSection collationStringSelector:@selector(contact_name)];，我当时查资料是，始终不明白这个@selector(contact_name) 中的contact_name 方法那儿来的，后来自己琢磨才明白，原来是要定义contact_name 属性，自动生成的get、set方法。
