用OC语言完成简易通讯录(实现增删改查)功能.

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8个功能：

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中.


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)

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信息

实现程序：
