仿趣頭條獲取系統通訊錄，並自定義通訊錄介面

阿新 • • 發佈：2018-12-09

我們有個專案需求要做一個方趣頭條的獲取通訊錄的要求，在此期間，對搜尋欄和邊欄首字母檢索，有些陌生，踩了一些坑。
先來看效果在這裡插入圖片描述

首先是獲取系統通訊錄，在iOS9之後，iOS對通訊錄的庫有了很大的改善。用起來很方便，但是點要注意在引用
#import <ContactsUI/ContactsUI.h>
#import <Contacts/Contacts.h>
這兩個庫的時候，需要手動新增.framework庫如下：在這裡插入圖片描述
如果不手動新增會出一個 clang 檔案的錯

“XLContact.h”

然後我們自定義一個通訊錄的model類

這裡要注意，我們定義這個model類一方面用來儲存聯絡人，一方面用來定義 contact_name 來讓程式碼對聯絡人按照首字母進行排序

注意這句程式碼NSArray *sortedPersonArrayForSection = [collation sortedArrayFromArray:personArrayForSection collationStringSelector:@selector(contact_name)];，我當時查資料是，始終不明白這個@selector(contact_name) 中的contact_name 方法那兒來的，後來自己琢磨才明白，原來是要定義contact_name 屬性，自動生成的get、set方法。
