[launchd-dev] launchd-dev Digest, Vol 41, Issue 5

[Per Ejeklint]

 OK, I get the idea, Thanks. Can't get it to work though. Here's example code:

NSString *installedToolPath = [[NSString alloc] initWithFormat:@"file://Library/PrivilegedHelperTools/se.ejeklint.mytool"];
NSDictionary *installedToolDict = [[NSBundle bundleWithURL:[NSURL URLWithString:installedToolPath]] infoDictionary];

and I get a NULL dictionary back. Same goes for the tool embedded in my app. URLs are ok. I have the link flag like this:

-sectcreate __TEXT __info_plist "$(SRCROOT)/daemon-info.plist" 

What have I missed?

Only thing is that the user must authenticate at every launch of the app and not just when the provided daemon is actually newer than the running one. Is there a way work around this with ServiceManagement framework? Or another simple way? I'm new to this part of Mac OS X stuff, so I apologize if I'm posting to the wrong list.
