Why won't the challenge accept this code (that I've checked in Xcode)?

I've been stuck at stage 3 of this code challenge, when it tells you to allocate and initialize a UIAlertView. The code I've used is: 

if(isCorrect == YES){
        UIAlertView * alertView = [[UIAlertView alloc] initWithTitle:@"Hooray!" message:@"You did it!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
}

And I've entered this code in Xcode and it compiles perfectly, but the code challenge throws a compilation error when I try this.

Any idea why?

You only need one nil at the end of the statment delete the ",nil".
