实现中等难度通讯录。需求:
1、定义联系⼈人类Contact。实例变量:姓名(拼⾳音,⾸首字⺟母⼤大写)、性别、电话号码、
住址、分组名称、年龄。⽅方法:⾃自定义初始化⽅方法(姓名、电话号码)、显⽰示联系⼈人信息
2、在main.m中定义字典,分组管理所有联系⼈人。分组名为26个⼤大写的英⽂文字⺟母。
3、可以添加联系⼈人对象,如果姓名或电话号码为空,添加失败。添加联系⼈人到匹配的分
组。
4、获取某个分组名称下所有联系⼈人,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人。
6、获取所有⼥女性的联系⼈人,并且按照年龄的降序排列。
7、根据姓名删除某个联系⼈人。
8、删除某个分组的全部联系⼈人。
