OC大作业_通讯录的实现

OC上机考试试题 ————通讯录

要求描述:⽤OC语言完成简易通讯录(实现增删改查)功 能.

(注:使⽤用MRC)

一、功能描述:

main函数中通过使用Person类和AddressBook类,创建对象、调⽤方法,实现以下要求 :

1).使⽤便利构造器创建四个Person类的实例(联系人).

姓名:Lucy 性别:⼥ 电话:123 年龄:21 姓名:Joe 性别:男 电话:456 年龄:17 姓名:Baby 性别:女 电话:789 年龄:27 姓名:Linda 性别:⼥ 电话:000 年龄:21

2).创建⼀一个AddressBook类的实例对象(通讯录). 3).使用AddressBook类中定义的⽅法实现:添加联系人,将四个联系人添加到通讯录

4).使⽤AddressBook类中定义的方法实现:根据电话查找联系人,并打印(查找电话456)

5).使用AddressBook类中定义的方法实现:根据性别查找联系人,并将查到的联系⼈按照年龄升序排序,并打印(查找性别:女)

6).使⽤AddressBook类中定义的方法实现:根据姓名,更改联系人信息.(修改Linda的 信息: 性别:女 电话:012 年龄:25);

7).使用AddressBook类中定义的⽅法实现:按照姓名删除联系人,并展示通信录中所 有人信息.(删除联系人:Baby)

8).使用AddressBook类中定义的方法实现:删除一个分组,并展示通信录中所有人信息.(删除L组) 所有联系人信息。

9).使用AddressBook类中定义的方法实现:实现3~8之间每个功能后,输出通讯录中所有联系人

以下代码是个人编写,不是按照题目中使用的联系人;

代码:
