Stuck on a question regarding objectAtIndex

I created an array called bookArray. Now the quiz asks me to create string variable and assign it the value of the 3rd item in the Array using objectAtIndex. I cannot get the right syntax by following the code written by Amit in the video. Please help.

I tried the following and it doesn't work:

NSString *bookTitles = bookArray [objectAtIndex:2.row];

Try this [bookArray objectAtIndex:2] after the equal sign.

Hi Gareth,

Sensational it works!

I put:

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

NSString *bookTitle = [booksArray objectAtIndex:2];

The frustrating thing is this syntax is never discussed in the videos. They put in the videos:

NSString *object = [self.titlesArray objectAtIndex:indexPath.row];

Thanks again.
