Making a string uppercase (Objective C)

Hello, The challenge asks me to make 'bookTitle' uppercase...

The code supplied does that but it appears that the challenge does not agree so. Any tips?

NSArray *booksArray = [NSArray arrayWithObjects:@"Hamlet", @"King Lear", @"Othello", @"Macbeth", nil];

NSString *bookTitle = [booksArray objectAtIndex:2];

bookTitle = [bookTitle upperCaseString];

Hi Brayden,

You have an uppercase C in upperCaseString, it should be uppercaseString, also you can do the following which is much tidier.

NSString *bookTitle = [[booksArray objectAtIndex:2] uppercaseString];

Wow, lifesaver! Thanks for that, did not realize that uppercaseString had a lower case C!
