ios - Add Array values to NSMutableDictionary -

i ran problem , can't find method on it. need make mutable dictionary values. values dynamic , them web service or 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 want add following tree dictionary can't figure how this.

i have necessary items in 2 nsarray artid , qty don't know how create bottom part can add dict.

carts {        cart {                 articleid : 22              quantity : 1             }        cart {                 articleid : 45              quantity : 3             }        ...       } 

i add [dict setobject:carts forkey:@"cart"] don't know how add values in such manner make dictionary on form presented you.

also, don't forget numbers or carts flexible. product.count.

thanks in advance.

if both array artid , qty have value @ same index create dictionary can try this

nsmutablearray *carts = [[nsmutablearray alloc] init]; for(nsinteger i=0; i<products.count; i++) {     //if have custom class `cart` use     cart *cart = [[cart alloc] init];     cart.articleid = [[products objectatindex:i] valueforkey:@"pid"];     cart.quantity = [[products objectatindex:i] valueforkey:@"qty"];      //if not have custom class 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 carts array dictionary key

[dict setobject:carts forkey:@"carts"];
