儲存：

        [NSKeyedArchiver archiveRootObject:self.contatcs toFile:contactsPath]; // 此種情況存的是contacts的集合

        [NSKeyedArchiver archiveRootObject:self.contact toFile:contactsPath]; // 此種情況存的contact對象

讀取：

　        self.contatcs =  [NSKeyedUnarchiver unarchiveObjectWithFile:contactsPath]; // 此種情況擷取的是contact的集合

　　      self.contact =  [NSKeyedUnarchiver unarchiveObjectWithFile:contactsPath]; // 此種情況擷取的是contact對象
