"Can't create that directory"

[kcorey]

Hi All,

I found a /hugely/ useful error message just now.

My app is called "WriteOn.app", at least for the moment.

I called 'create folder' with the path to my app on my iPad:
/var/mobile/Applications/706ECCCF-DC1D-42F1-B71E-F3D96610DAEF/WriteOn.app/Downloaded

The error in 'the result' is "can't create that directory". Just lovely. Might as well put the "engine" light on my iPad. It would tell me as much.

Can anyone shed a tiny bit more light on that error message?
It /shouldn't/ be permissions, because it's within my app's sandbox.
It can't be space, as I've got 2.4GB remaining.
It shouldn't be rights, as the standalone downloads to the iPad just fine and is attempting to run when this error happens.
I don't have AFAICT any other app using the same signature (but that shouldn't matter anyway, should it)?

Are there any other reasons why one can't create a folder on iOS from within LiveCode?

Thanks,

-Ken

Hi Ken,

this IS a permission problem!
You are not allowed to write in the "Application" folder <specialfolderpath("engine")> on iOS!

Use the documents folder -> specialfolderpath("documents")

"can't create that directory/file" always points to a permission probem,
but yes, the error could be a tad more informative

Check "File and Folder Handling" in the "iOS Release Notes" -> Menu: Help

Hi Ken,

please don't forget, you read it here first!
