OC实现通讯录

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: 电话:123 年龄:21

         姓名:Joe 性别: 电话:456 年龄:17

         姓名:Baby 性别: 电话:789 年龄:27

         姓名:Linda 性别: 电话:000 年龄:21

    2).创建一个AddressBook类的实例对象(通讯录).

    3).添加联系人,将四个联系人添加到通讯录中.

    4).根据电话查找联系人,并打印(查找电话:456);

    5).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:)

    6).根据姓名,更改联系人信息.(修改Linda的信息: 性别: 电话:012 年龄:25);

    7).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).删除一个分组,并展示通信录中所有人信息.(删除L)

    9).实现3~8之间每个功能后,输出通讯录中所有联系人信息。
