1,773 PointsThe Quiz doesn't accept my Array
I put the following:
self.booksArray = [NSArray arrayWithObjects:@"Hamlet",@"King Lear",@"Othello",@"Macbeth", nil];
It keeps complaining that I din't use the array name "booksArray" or there's something wrong with the syntax.
Can anyone give me some help?

1,773 PointsOkay, I went back to a previous lesson on NSArray and typed in the following that worked.
NSArray *booksArray = @[@"Hamlet",@"King Lear",@"Othello",@"Macbeth"];
However, Amit uses the:
self.booksArray = [NSArray arrayWithObjects:@"Hamlet",@"King Lear",@"Othello",@"Macbeth", nil];
in the video so I was assuming I could use the way he coded the Array in the quiz! Very frustrating!

it asks you to create an array. just an array, it does NOT say to use an array property (there isnt one). if it said to use the property booksArray then yes using self.booksArray would work. However in this case you are not using a property, which is why you dont use self.booksArray

3,634 PointsAfter a few attempts, I entered: NSArray *booksArray = @[@"Hamlet",@"King Lear",@"Othello",@"Macbeth"];
And it did not work. The editor cursor was all over the place. I then spent ages trying everything including self....
A complete waste of time and utterly frustrating.
I will try a few more of these, but if this frustration is typical in your teaching style - goodbye Treehouse.
The solution is simple, give people a few goes and then provide the answer or hints.
