Why can not inserted third item to the string

Create a string variable called 'bookTitle' and assign it the third item from the 'booksArray'.

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

NSString *bookTitle = [self.booksArray objectAtIndex:2];

your booksArray object is not a property, so you dont reference it using self. you just the the variable name. try

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

NSString *bookTitle = [booksArray objectAtIndex:2];
