Code Challenge What is NSDictionary? from IOS "Getting Data from the Web"

In the Code Challenge: Create an NSDictionary object called book1 with the following keys and values: 'Title' - 'Art of War', 'Author' - 'Sun Tzu'

I don't understand what is wrong with my answer? Thank you for your help, Mark. NSDictionary *book1 = [NSDictionary dictionaryWithObjectsAndKeys:@"Art of War",@"title",@"Sun Tzu",@"author", nil];

I don't think I'm spoiling anything by saying this: your syntax is just fine, but in this example, it wants the keys to be capitalized: so use 'Title' and 'Author' instead of 'title' and 'author'. I had this same problem.

You are correct, a capitalized "Title" and "Author" fixed the problem. Thank you very much, Nathan
