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：
