Maintaining the order while iterating a NSDictionary

Question

I have a NSDictionary which im iterating and Im saving the datas to core data as follows,

NSDictionary *details = [valueDict objectForKey:@\"shipment_master\"];
         


        

Answer 1

NSMutableDictionary is not ordered. There is nothing you can do to guarantee the order of keys because NSDictionary makes no attempt to preserve any particular ordering. To go over a dictionary in a particular order, you have to make an NSArray of the keys that is in the order you want, then iterate that and fetch the corresponding values.
