I would like to use this method, or kind of…

i have a NSDictionnary and i want to replace this :

[[rootObj objectAtIndex:0] valueForKey:@”check”]

there is this method :

rootObj replaceObjectAtIndex:<#(NSUInteger)#> withObject:<#(id)#>

Answer 1

use this code for replace code

EDIT: Update answer according to user’s match

NSMutableDictionary *newDict = [[NSMutableDictionary alloc] init]; 
NSDictionary *oldDict = (NSDictionary *)[rootObj objectAtIndex:0]; 
[newDict addEntriesFromDictionary:oldDict];
[newDict setObject:@"1" forKey:@"check"];
[rootObj replaceObjectAtIndex:0 withObject:newDict];

In the above example i want to replace the object of @”Sales Qty”
so i have create dictionary and set the object in those dictionary then just set the value for @”Sales Qty” key and replace the whole dictionary in array
