Exploring the Master-Detail Template

Challenge #1

Create an array named 'booksArray' with the following book titles: 'Hamlet', 'King Lear', 'Othello', 'Macbeth'.

Is there a booksArray property already defined? If not you'll have to make one. Try:

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

Use just comma's instead of semi-colons to separate the objects.

Bummer! Make sure you created an array with the correct variable name, and check your syntax!

Challenge # 2:

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

My code:

NSString *bookTitle = @"Othello";

Result:

Bummer! The method for finding an object in an array at a given index was not called.

Help! This is driving me nuts! Challenge is nowhere in the previous video :(
