Array of objects via parameters in AFNetworking - ios

Question

I could able to POST the parameters as follows, it works if I have only one item for each dictionary item. In the following params I have only one pName and one price.
NSMutableDictionary *params= [NSMutableDictionary dictionaryWithDictionary:
#{#"pName":pData.pName,
#"price":pData.price,
#"notes":pData.notes}];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:#"text/html",nil];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
[manager POST:URL_SIGNIN parameters:params progress: nil
success:^(NSURLSessionTask *operation, id responseObject)
{
NSLog(#"JSON: %#", responseObject);
}
failure:
^(NSURLSessionTask *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
However, I wonder how could I able to put items as a parameters if I have more than one items such as pNames = [Beef, Coffee, Rice ,Sprite] and prices = ["$10", $"3", "$5", #"1"].
Consider as following object at the end.
orders = {#"Beef" : #"$10",#"Coffee" : #"$3", #"Rice" : #"$5", #"Sprite" : #"$1"}
Assume that it is restaurant application where user selects multiple items to check out.

You want an array ($[]), not a dictionary (${}).
In your example:
prices = #[#"$10", #"$3", #"$5", #"$1"];
EDIT:
As parameters:
NSMutableDictionary *params= [NSMutableDictionary dictionaryWithDictionary:
#{#"prices": #[#"$10", #"$3", #"$5", #"$1"]}];
OR:
NSArray *prices = #[#"$10", #"$3", #"$5", #"$1"];
NSMutableDictionary *params= [NSMutableDictionary dictionaryWithDictionary:
#{#"prices": prices];
