1.創(chuàng)建AddressBook類.
1)使用字典作為容器,字典的Key值為分組名(姓名首字母负拟，大寫),value值為數(shù)組,數(shù)組中存放聯(lián)系人(Person實(shí)例).
2)添加聯(lián)系人.要求
a.判斷姓名和電話不能為空否則添加失敗.
b.判斷是否已經(jīng)存在分組,存在直接存儲(chǔ).不存在創(chuàng)建分組后再存儲(chǔ).(注:聯(lián)系人不能有重名).
c.添加成功返回YES,姓名為空或者有重名的添加失敗返回NO.
d.數(shù)據(jù)使用Person存儲(chǔ).
e.方法:- (BOOL)addPerson:(Person *)aPerson;
2.獲取某個(gè)分組名稱下所有聯(lián)系人,并且按照姓名升序排列毅弧。
3.從通訊錄中根據(jù)電話號(hào)碼搜索聯(lián)系?人授滓。
4.獲取所有?女性的聯(lián)系?,并且按照年齡的降序排列。
5.根據(jù)姓名刪除某個(gè)聯(lián)系?真屯。
6.刪除某個(gè)分組的全部聯(lián)系?誊役。
