如何自定义iOS通讯录

苹果给用户提供了自己的通讯录，但是根据业务的需求，需要自定义通讯录，我们就需要根据业务需求来自定义。
首先我们需要知道苹果的提供的一些Foundation、UIKit框架，了解其中的一些特性，可以打开手机查看苹果系统提供的原生的通讯录，可以看到：

1.搜索框
2.右侧搜索条
3.联系人分组
4.添加联系人
5.获取联系人头像及联系方式

根据需求，可以总结出自定义通讯录需要做的一些功能，一项大的功能可以差分成一些小的功能，然后一个一个实现，将复杂的问题差分成小问题解决。

1.自定义搜索框
2.获取首字母
3.权限判断
4.排序
5.自定义搜索
6.自定义联系人界面（考虑多值的情况，获取通讯录头像）

简答介绍下排序：

IOS项目中会用到对通讯录的联系人或是会员按姓名为关键字排序，因为NSArray并不直接支持对汉字的排序，这就要通过将汉字转换成拼音完成按A~Z的排序，这看起来是个头疼的问题，因为牵扯到汉字转为拼音，获取汉字的首字的首字母，如将“王”变成“W”。

函数原理是：我们知道，在Objective C语言中，字符串是以unicode进行编码的。在unicode字符集中，汉字的编码范围为4E00 到 9FA5 之间（即从第19968开始的20902个字符是中文简体字符）。我们把这些字符的拼音首字母按照顺序都存放在一个char数组中。当我们查找一个汉字的拼音首字母时，只需把这个汉字的unicode码（即char强制转换为int）减去19968，然后用这个数字作为索引去找char数组中存放的字母即可。
给出项目的源码，注释很清楚。代码如：
RYAddressBook.h

#import <Foundation/Foundation.h>
#import "RYPersonInfo.h" 

typedef void (^AddressBookBlock) (NSArray *personInfos); 

@interface RYAddressBook : NSObject 

/**
 * 将数字转化为字母 0~26 1~25=a~z 26=#
 */

/**
 * 获取索引
 */
int Index(NSString *firstSpell);
/**
 * 获取用户所有通讯录信息
 *
 * @return 所有通讯录数据信息数组
 */
+ (void)getPersonInfo:(AddressBookBlock)addressBookBlock; 

/**
 * 根据关键字匹配所有用户信息
 *
 * @param keyWord 匹配关键字
 *
 * @return 匹配到的通讯录数据信息数组
 */
+ (void)searchPersonInfo:(NSString *)keyWord addressBookBlock:(AddressBookBlock)addressBookBlock; 

/**

 *
 * @param personInfos 获取的通讯录数据信息数组
 */
