Add Array values to NSMutableDictionary - ios

Question

I ran into a problem and I can't find the method to get over it. basically I need to make a mutable dictionary with some values. All values are dynamic and I get them from web service or from other variables.
NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
[dict setObject:comment.text forKey:#"Comment"];
[dict setObject:name.text forKey:#"Name"];
[dict setObject:[NSString stringWithFormat:#"%d",isPublic] forKey:#"VisibleForAll"];
po dict
{
Comment = "no comment";
Name = "test";
VisibleForAll = 1;
-> carts
}
Furthermore I want to add the following tree to my dictionary but I can't figure how to do this.
I have the necessary items in 2 NSArray artID and qty but I don't know how to create the bottom part so I can add it to the dict.
Carts {
Cart {
ArticleID : 22
Quantity : 1
}
Cart {
ArticleID : 45
Quantity : 3
}
...
}
I will add it with [dict setObject:carts forKey:#"Cart"] but I don't know how to add values in such a manner that I will make my dictionary on the form I presented you.
Also, don't forget that the numbers or Carts is flexible. I will get it from a Product.count.
Thanks in advance.

Answer 1

If your both array artID and qty have value at the same index for create a dictionary you can try like this
NSMutableArray *carts = [[NSMutableArray alloc] init];
for(NSInteger i=0; i<products.count; i++) {
//If you have custom class `cart` than use that
Cart *cart = [[Cart alloc] init];
cart.ArticleID = [[products objectAtIndex:i] valueForKey:#"pid"];
cart.Quantity = [[products objectAtIndex:i] valueForKey:#"qty"];
//If you not have any custom class than use Dictionary
NSMutableDictionary *cart = [[NSMutableDictionary alloc] init];
[cart setObject:[[products objectAtIndex:i] valueForKey:#"pid"] forKey:#"ArticleID"];
[cart setObject:[[products objectAtIndex:i] valueForKey:#"pid"] forKey:#"Quantity"];
}
Now add this carts array to Dictionary with key
[dict setObject:carts forKey:#"carts"];

Answer 2

NSArray *pid = [products valueForKey:#"pid" ];
NSArray *qty = [products valueForKey:#"qty"];
NSMutableArray *carts = [[NSMutableArray alloc] initWithCapacity:products.count];
for(NSInteger i=0; i<products.count; i++) {
NSMutableDictionary *cart = [[NSMutableDictionary alloc] init];
NSMutableDictionary *cartemp = [[NSMutableDictionary alloc] init];
[cart setObject:[pid objectAtIndex:i] forKey:#"ArticleId"];
[cart setObject:[qty objectAtIndex:i] forKey:#"Quantity"];
[cartemp setObject:cart forKey:#"Cart"];
[carts addObject:cartemp];
}
[dict setObject:carts forKey: #"Carts"];
