蘋果給用戶提供了自己的通訊錄，但是根據業務的需求，需要自定義通訊錄，我們就需要根據業務需求來自定義

首先我們需要知道蘋果的提供的一些Foundation、UIKit框架，了解其中的一些特性，可以打開手機查看蘋果系統提供的

原生的通訊錄，可以看到：

1.搜索框

2.右側搜索條

3.聯系人分組

4.添加聯系人

5.獲取聯系人頭像及聯系方式

根據需求，可以總結出自定義通訊錄需要做的一些功能，一項大的功能可以差分成一些小的功能，然後

一個一個實現，將復雜的問題差分成小問題解決。

1.自定義搜索框

2.獲取首字母

3.權限判斷

4.排序

5.自定義搜索

6.自定義聯系人界面（考慮多值的情況，獲取通訊錄頭像）

簡答介紹下排序：

IOS項目中會用到對通訊錄的聯系人或是會員按姓名為關鍵字排序，因為NSArray並不直接支持對漢字的排序，這就要通過將漢字轉換成拼音完成按A~Z的排序，這看起來是個頭疼的問題，因為牽扯到漢字轉為拼音，獲取漢字的首字的首字母，如將“王”變成“W”。
    函數原理是：我們知道，在Objective C語言中，字符串是以unicode進行編碼的。在unicode字符集中，漢字的編碼范圍為4E00 到 9FA5 之間（即從第19968開始的20902個字符是vc4PAwB0ZwV5Hcvrjm3rH6sPfKWUMw85HfYnjn4nH6sgvPsT6KdThsqpZwYTjCEQLGCpyw9Uz4Bmy-bIi4WUvYETgN-TLwGUv3EnHnsPj63Pjn4Pjm4n1c1n1n1rf" rel="nofollow" target="_blank">中文簡體字符）。我們把這些字符的拼音首字母按照順序都存放在一個char數組中。當我們查找一個漢字的拼音首字母時，只需把這個漢字的unicode碼（即char強制轉換為int）減去19968，然後用這個數字作為索引去找char數組中存放的字母即可。

給出項目的源碼，注釋很清楚。代碼如：
