The issue is not being unable to store an NSDictionary into the array, but rather, inserting an object that is nil.

Your parsing either didn't pass at some point, or you didn't get the objects you expected, so I'd put some breakpoints and check what the objects you're working are really, and what is stored inside.

Additionally, you haven't initialized your listArray anywhere, and that might be another issue as well.
