通讯录(中级)

来源：互联网发布：windows 活动目录管理编辑：程序博客网时间：2024/05/04 13:05

实现中等难度通讯录。需求：
1、定义联系人类AddressContact。实例变量：姓名（拼音，首字母大写）、性别、电话号码、住址、分组名称、年龄。方法：自定义初始化方法（姓名、电话号码）、显示联系人信息 

2、在main.m中定义字典，分组管理所有联系人。分组名为26个大写的英文字母。 

3、可以添加联系人对象，如果姓名或电话号码为空，添加失败。添加联系人到匹配的分组。 

4、获取某个分组名称下所有联系人，并且按照姓名升序排列。 

5、从通讯录中根据电话号码搜索联系人。

 6、获取所有女性的联系人，并且按照年龄的降序排列。 

7、根据姓名删除某个联系人。

 8、删除某个分组的全部联系人。
