Thanks for you help guys, I;ve gotten a bit closer to solving my
problem. It seems I can't simply call an instance of a custom class by
making a variable with it as I had before:

ACRQuizProblemRowElement *newElement;

But instead needed to explicity allocate and initialize it:

ACRQuizProblemRowElement *newElement = [[ACRQuizProblemRowElement alloc] init];

Also taking your advice, my setters now utilize this format:

- (void) setContent: (NSString *)newContent
{
[_content release];
_content = [newContent copy];
}

This works fine in most situations, except when I am trying to set the array.

- (void) setAnswers: (NSArray *)newAnswers
{
[_answers release];
_answers = [NSArray copy];
}
