OC 字典 存储联系人信息 求大神优化代码

1、定义联系?人类Contact。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。
