LiveCode Forums.

I've had an app rejected a couple of times by Apple to due data stacks being too big. They suggest that I set the stack files' "do not backup" attribute. The problem that I'm running into is that I cannot seem to set the attribute for a stack residing in the "engine" area.

When a user opens the app for the first time, it throws a copy of the "engine" stack into the documents area. The app uses the "documents" stack to maintain data within the app. At some point, however, users will want to reset the app to its baseline. When this happens, the "engine" stack is once again copied to the "documents" stack.

The code below executes when the "Launcher" stack is initially opened. The "documents" stack successfully has its "do not backup" flag set, but the "engine" stack does not.

I've seen posts where folks suggest that rather than use the documents area, the cache area should be used. I'm concerned that this would not work as users may lose the data stacks if the cache folder is flushed.

Any help would be greatly appreciated!

Hi,

Would it help if you compress those stacks before making a standalone and decompress them when writing them to the documents folder? I don't see a way to set the dontBackup flag for files that are part of the standalone.

Kind regards,

Mark
