Trying to uppercase a string

Real quick question: Where does the variable to make the string uppercase go so that the NSLog will print the string uppercase?

NSArray *booksArray = [NSArray arrayWithObjects:@"Hamlet", @"King Lear", @"Othello", @"Macbeth", nil]; NSString *bookTitle = [booksArray objectAtIndex: 2]; NSLog(@"%@", bookTitle, uppercaseString);

The problem is in uppercaseString--otherwise everything works.

This is returning an error and I looked through my past intro to objective-c material and cannot find the solution to this.

Thanks in advance.

you dont need to use NSLog, simply use the NSString method uppercaseString. call that method like so:

NSArray *booksArray = [NSArray arrayWithObjects:@"Hamlet", @"King Lear", @"Othello", @"Macbeth", nil];
NSString *bookTitle = [[booksArray objectAtIndex: 2] uppercaseString];

the string thats at index 2 of your books array will be uppercased
