Replace a value in NSDictionary in iPhone

Question

I have a array (dataArray) of NSDictionary \"item\". It has datas like \"david\" for key \"name\" and \"85\" for key \"marks\" etc for 5 students. I want to replace the mark

Answer 1

You first need an NSMutableDictionary with it you can change the key and value.

It would be like this:

NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithObjectsAndKeys:@"david", @"name", "85", @"marks", nil];

[dict setObject:@"90" forKey:@"david"];
