If you want to get data from dictionary and add them into an array below code will help you, In this blog firstly i have created a NSMutableAarray and after that created a NSArray which contain the value like ram,13 etc then i created a NSMutableDictionary which create a key for array after that i have added all the data from dictionary into a mainArray and display all the data.

            NSMutableArray *mainArray = [NSMutableArray array];

            NSArray *array1 = [NSArray arrayWithObjects:@"Ram",
                     [NSNumber numberWithInteger:13],

                     [NSArray arrayWithObjects:@"Kumar",@"Singal",nil],

                     nil];

NSLog(@"The array contain the following element %@",array1);


NSMutableDictionary *dict = [NSMutableDictionary dictionary];
[dict setObject:array1 forKey:@"data"];

NSLog(@"the dictionary is %@",dict);

[mainArray addObjectsFromArray:[dict objectForKey:@"data"]];

NSLog(@"main array is %@",mainArray);
