Question

我有来自服务器的数据，例如

名称地址电话

有没有办法让我创建一个像以下的NSDictionary：

(
  name=a_name,
  address=a_address,
  telephone=a_telephone
),
(
  name=b_name,
  address=b_address,
  telephone=b_telephone
)

然后，我将这个字典插入另一个字典。

所以基本上我会有一本下面的词典;

(
  User=me,
  Details
  (
    name=a_name,
    address=a_address,
    telephone=a_telephone
  ),
  (
    name=b_name,
    address=b_address,
    telephone=b_telephone
  )
)

我对数组和字典之间的使用感到困惑。

我有ff：code：

[test addObject:dictionary];

test是ns可变数组

这是一个数组，但是，我觉得如何将它添加到字典中很奇怪，因为没有方法可以添加数组值和只是字符串的键。

所以问题可能会拖延到如何将数组对象添加到NSDictionary。

感谢。

Answer 1

试试这个：

NSMutableArray *arr = [[NSMutableArray alloc]init];

while (response) {
    NSMutableDictionary *dict = [[NSMutableDictionary alloc]init];
    [dict setObject:@"name_i" forKey:@"name"];
    [dict setObject:@"address_i" forKey:@"address"];
    [dict setObject:@"telephone_i" forKey:@"telephone"];
    [arr addObject:dict];
}

还可以将Array添加到Dictionary

中

NSMutableDictionary *totalDict = [[NSMutableDictionary alloc]init];

[totalDict setObject:@"Me" forKey:@"User"];
[totalDict setObject:arr forKey:@"Details"];

   NSArray *dictionary = @[
                              @{
                                @"Source_lat": @"28.6287",
                                @"Source_lon": @"77.3208",
                                @"Dest_lat": @"28.628454",
                                @"Dest_lon": @"77.376945",
                                @"S_address": @"Vaishali,Delhi",
                                },
                              @{
                                  @"Source_lat": @"28.628454",
                                  @"Source_lon": @"77.376945",
                                  @"Dest_lat": @"28.5529",
                                  @"Dest_lon": @"77.3367",
                                  @"S_address": @"Noida Sec 63",
                                  },
    @{
                                  @"Source_lat": @"28.5529",
                                  @"Source_lon": @"77.3367",
                                  @"Dest_lat": @"28.6276",
                                  @"Dest_lon": @"77.2784",
                                  @"S_address": @"Noida Sec 44",
                                  },
     @{
                                  @"Source_lat": @"28.6276",
                                  @"Source_lon": @"77.2784",
                                  @"Dest_lat": @"28.6287",
                                  @"Dest_lon": @"77.3208",
                                  @"S_address": @"Laxmi Nagar,Delhi",
                                  },



                             ];

Answer 3

您应创建NSMutableDictionary，然后使用setObject:ForKey添加NSArray。

NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
[dict setObject:test forKey:@"test"];

Answer 4

你可以有一个字典数组。

 NSMutableArray *arr = [[NSMutableArray alloc]init];
NSMutableDictionary *dict = [[NSMutableDictionary alloc]init];

while (response) {
    [dict setObject:@"name_i" forKey:@"name"];
    [dict setObject:@"address_i" forKey:@"address"];
    [dict setObject:@"telephone_i" forKey:@"telephone"];
    [arr addObject:dict];
    [dict removeAllObjects];  
}

如果您愿意，也可以使用词典。

NSMutableDictionary *totalDict = [[NSMutableDictionary alloc]init];

        [totalDict setObject:dict forKey:@"i"];

是否可以拥有一个NSDictionary数组
