It sounds like:
Code:
[[NSBundle mainBundle] resourcePath]
would get you what you want, but I am going to really, really recommend against doing this if you are going to write to that location. A much better target would be to write out to folders in ~/Library/Cache or ~/Library/Application Support. Or you could write out to the a folder in the users /var/folders folder (use confstr() with _CS_DARWIN_USER_TEMP_DIR, to get that). But I would caution against that last one, as it is not commonly known to users that that exists, and filling up their drive in a spot they are not likely to find is likely to make them angry.
