OK. After nearly a week of head-banging, I'm just about ready to throw in the
towel, dump sandboxing and potentially the Mac App Store altogether.
I spent the best part of yesterday reinventing the wheel and implementing my
own scheduling mechanism to put into a helper app which would run in the
background constantly as a login item... the timing/scheduling bit works fine,
but the helper app can't actually DO anything because it runs in a different
sandbox from the main app!! This means I can't access the user's preferences
without a temporary entitlement, and can't access the resources within my main
app at all.
My helper app sits in Main.app/Contents/Library/LoginItems/MainHelper.app and
is launched (based on user prefs) by calling
SMLoginItemSetEnabled((CFStringRef)[NSString stringWithString:@"<my app
identifier>.helpername"], true)
I've tried giving the helper the same bundle identifier as the main app, but
that doesn't work (as expected, but I wanted to try anyway!).
I've even tried getting the path of the helper app ([[NSBundle mainBundle]
bundlePath]) and removing the last 4 path components to get the path to the
main application and launching it via NSWorkspace, so that I could then launch
my helper that way and inherit the sandbox, but sandboxd gives more permission
violations when attempting to launch the main application. I suspect that
would have been cause for appstore rejection anyway!
I feel like I've missed something obvious, but I just can't see it. Is there a
way to make the helper app run in the same sandbox as the main app?
Many thanks for your help.
Mark
