对象中的NSMutableDictionary和NSMutableArray对象

Question

我用NSDictionary和NSArray为我的头粉碎了我的脑袋。

我得到2个可变数组，我想合并它们。

的NSMutableArray 1：

{ 
     email = "a@a1.com"; 
     "password" = "2017-05-23 13:08:03"; 
    } 

的NSMutableArray 2

(
     { 
     "created_at" = "2017-06-22 00:00:00"; 
     "id_weather_city" = 1; 
     name = Cityname; 
     "updated_at" = "2017-06-22 00:00:00"; 
    }, 
     { 
     "created_at" = "2017-06-22 00:00:00"; 
     "id_weather_city" = 2; 
     name = Cityname2; 
     "updated_at" = "2017-06-22 00:00:00"; 
    } 
) 

我想他们这样的结合在一起，但我不知道如何正确 数组：

{ 
    email = "a@a1.com"; 
    "password" = "2017-05-23 13:08:03"; 
    "weather":(
     { 
     "created_at" = "2017-06-22 00:00:00"; 
     "id_weather_city" = 1; 
     name = Cityname; 
     "updated_at" = "2017-06-22 00:00:00"; 
    }, 
     { 
     "created_at" = "2017-06-22 00:00:00"; 
     "id_weather_city" = 2; 
     name = Cityname2; 
     "updated_at" = "2017-06-22 00:00:00"; 
    } 
) 
} 

Answer 1

第一个不是数组，它是一个字典。知道，你可以做

NSMutableDictionary *dict = [item1 mutableCopy]; 
dict[@"weather"] = [item2 copy]; 

只需复制的第一部字典，然后将第二个为weather关键

Answer 2

试试这个：

NSMutableDictionary *finalDictionary = [[array1 objectAtIndex : 0] mutableCopy]; 
[finalDictionary setValue : array2 forKey:@"weather"];
