NSArray of NSArray creation

Question

In my app I've to create a structure like this:

$arrProducts = array(
    array(
        “product_id” => “1”,
        “qty” => 2
                "options" => array(         
                    optionId_1 => optionValue_1,
                    ...,
                    optionId_n => optionValue_n
                 )

I did this array of array so:

NSDictionary *dict = @{
       @"product_id" : productID,
       @"qty": self.qty
   };
NSArray *array2 = @[dict];

This array should work with a Magento store, when I run the app it shows me this message:

error cart_product.add: SQLSTATE[21000]: Cardinality violation: 1241 Operand should contain 1 column(s)

I guess this problem, depends on how I create this array, but I'm not understanding what's wrong with this array, can you help me to fix it?

UPDATE:

The library I'm using to connect to Magento needs this structure:

[Magento call:@[@"customer.create", @{
     @"email": email,
     @"password": password,
     @"firstname": firstname,
     @"lastname": lastname,
     @"website_id": @1,
     @"store_id": Magento.service.storeID
}] success:^(AFHTTPRequestOperation *operation, id responseObject) {
    Magento.service.customerID = responseObject;
    NSLog(@"signUp customerID = %@", Magento.service.customerID);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"error %@", error.localizedDescription);
}];

I will use it to add a product into a cart if you take a look in Magento SOAP API to add a product to cart you can see that in phpthey add product by using an array of an array. I need to replicate the same structure.

Did you consider using a dictionary, as it seems to be more like a key/value based structure. — Leijonien

I need to do a stuff like this, because the library I'm using to connect to Magento needs the structure I will show you in my question — lucgian841

First, you put an NSDictionary in an array, and after that you do it again. That's wrong. Do it like this:

NSDictionary *product1 = @{@"product_id" : productID, @"qty": self.qty, "options" : @{optionId_n : optionValue_n}};
NSDictionary *product2 = @{@"product_id" : productID, @"qty": self.qty, "options" : @{optionId_n : optionValue_n}};
NSArray *products = @[product1, product2];

It's not the same I did in my code? I will add only one product, so I guessed I've to create a single NSDictionary and then I need to put this NSDictionary in an NSArray

I tried it and it doesn't work... It gives me the same error: error SQLSTATE[21000]: Cardinality violation: 1241 Operand should contain 1 column(s)
