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

If you have still problem then let me know

Firstly get all keys like this:

    NSArray *arrKeys = [yourDictionary allKeys];

Now replace like this say u want replace second object :

 if([arrKeys objectAtIndex:1]) //key for second Object
 {
   [yourDictionary setObject:yourNewValueHere forKey:[arrKeys objectAtIndex:1]]; //it overwrites value
 }
