hey! i am trying to do the Modifying the master detail template but i keep getting stuck on the last thing!! can someone help? it says i need to capitalise it so here is my code
NSArray *booksArray = [[NSArray alloc]initWithObjects:@"Hamlet", @"King Lear", @"Othello", @"Macbeth", nil]; NSString *bookTitle = [[booksArray objectAtIndex:2] bookTitle uppercaseString];
then i tried to make it like this:
NSArray *booksArray = [[NSArray alloc]initWithObjects:@"Hamlet", @"King Lear", @"Othello", @"Macbeth", nil]; NSString *bookTitle = [booksArray objectAtIndex:2]; bookTitle = [bookTitle uppercaseString];
and that didn't work so i then tried this:
NSArray *booksArray = [[NSArray alloc]initWithObjects:@"Hamlet", @"King Lear", @"Othello", @"Macbeth", nil]; NSString *bookTitle = [booksArray objectAtIndex:2]; [bookTitle uppercaseString];
but i still don't know what is wrong can someone help me?!

NSArray *booksArray = [[NSArray alloc] initWithObjects:@"Hamlet", @"King Lear", @"Othello", @"Macbeth", nil];
NSString *bookTitle = [booksArray objectAtIndex:2];
//bookTitle is now all uppercase
[bookTitle uppercaseString];

42,016 PointsCan you provide a link to the challenge?
its already capitalized in the literal value in your array so shouldnt have to call any additional methods to capitalize it. did you try
NSArray *booksArray = [[NSArray alloc]initWithObjects:@"Hamlet", @"King Lear", @"Othello", @"Macbeth", nil];
NSString *bookTitle = [booksArray objectAtIndex:2]

24,657 Pointsi just did what you did and it said this "Bummer! There was no method called to convert the string to uppercase." am i being really silly?

42,016 Pointssorry, I thought you were on task 2 for a minute. see my other post below about what you did wrong

24,657 Pointsthank you so much!!!!!!!! it worked!!! i wonder why it didn't the first time haha!

42,016 Pointsno problem. the challenge most likely wanted it in 2 separate lines in order to keep the code for task 2 and task 3 separate.
//task 1 code
NSArray *booksArray = [[NSArray alloc] initWithObjects:@"Hamlet", @"King Lear", @"Othello", @"Macbeth", nil];
//task 2 code
NSString *bookTitle = [booksArray objectAtIndex:2];
//task 3 code
//bookTitle is now all uppercase
[bookTitle uppercaseString];
whereas at first you had
//task 1 code
NSArray *booksArray = [[NSArray alloc] initWithObjects:@"Hamlet", @"King Lear", @"Othello", @"Macbeth", nil];
//you combined task 2 and 3 code into one line, so the challenge thinks task 2 is no longer passing
NSString *bookTitle = [[booksArray objectAtIndex:2] bookTitle uppercaseString];
It gives the correct output, but task2 is expecting the bookTitle to be @"Othello", not @"OTHELLO" so the challenge thinks task 2 is no longer passing.
