實作中等難度通訊錄。需求:
1、定義聯系⼈人類contact。執行個體變量:姓名(拼⾳音,⾸首字⺟母⼤大寫)、性别、電話号碼、 住址、分組名稱、年齡。⽅方法:⾃自定義初始化⽅方法(姓名、電話号碼)、顯⽰示聯系⼈人資訊
2、在main.m中定義字典,分組管理所有聯系⼈人。分組名為26個⼤大寫的英⽂文字⺟母。
3、可以添加聯系⼈人對象,如果姓名或電話号碼為空,添加失敗。添加聯系⼈人到比對的分 組。
4、擷取某個分組名稱下所有聯系⼈人,并且按照姓名升序排列。
5、從通訊錄中根據電話号碼搜尋聯系⼈人。
6、擷取所有⼥女性的聯系⼈人,并且按照年齡的降序排列。
7、根據姓名删除某個聯系⼈人。
8、删除某個分組的全部聯系⼈人。
