OC之实现中级通讯录

OC之实现中级通讯录

//实现中级通讯录.

/作业1: 实现通讯录.需求:
        //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./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, 并且按照年龄的升序排列.
        //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
