In the game my dev team is doing next, we're trying to figure out how to do the levels. It will come with about 80 levels, than we're going to make DLC. We were wondering if the in-app purchases need to use plists or if we can make the levels in code. The plists would be easier, but would make the online score boards horrible because they would be cheated to holy hell. While code would be harder to hack, but we're not sure if we can use it for the DLC? Can someone explain how exactly the in-app purchases work? We know about the code part, but we don't know how the download gets used, what types of files are allowed in the DLC, etc.
