After hell of searching and experimenting I am ready to answer my own question, so others can save their time and efforts.
My conclusion is that for now there is no way HelperApp can launch MainApp with some arguments under the Sandbox. At least I have not found any way to do that.
Launch MainApp like this:
[[NSWorkspace sharedWorkspace] launchApplication:newPath];
In MainApp add the following:
Application_IsLaunchedByHelperApp = YES;
ProcessSerialNumber currPSN;
OSStatus err = GetCurrentProcess(&currPSN);
if (!err)
{
// Get information about our process
NSDictionary * currDict = [(NSDictionary *)ProcessInformationCopyDictionary(&currPSN,
kProcessDictionaryIncludeAllInformationMask) autorelease];
// Get the PSN of the app that launched us. Its not really the parent app, in the unix sense.
long long temp = [[currDict objectForKey:@"ParentPSN"] longLongValue];
long long hi = (temp >> 32) & 0x00000000FFFFFFFFLL;
long long lo = (temp >> 0) & 0x00000000FFFFFFFFLL;
ProcessSerialNumber parentPSN = {(UInt32)hi, (UInt32)lo};
// Get info on the launching process
NSDictionary * parentDict = [(NSDictionary*)ProcessInformationCopyDictionary(&parentPSN,
kProcessDictionaryIncludeAllInformationMask) autorelease];
// analyze
// parent app info is not null ?
if (parentDict && parentDict.count > 0)
{
NSString * launchedByAppBundleId = [parentDict objectForKey:@"CFBundleIdentifier"];
if (![launchedByAppBundleId isEqualToString:HELPER_APP_BUNDLE_ID])
{
Application_IsLaunchedByHelperApp = NO;
}
}
}
That's it. Application_IsLaunchedByHelperApp
now has correct value.
The solution is not mine. I've found it on the web (cocoabuilder, I guess). Good luck to everyone! And thanks for your attention to my questions.
UPDATE
Looks like there are cases when launched at login app shows launchedByAppBundleId = @"com.apple.loginwindow"
. So the last part of code will look like this:
//
// analyze
//
// parent app info is not null ?
if (parentDict && parentDict.count > 0)
{
NSString * launchedByAppBundleId = [parentDict objectForKey:@"CFBundleIdentifier"];
if (![launchedByAppBundleId isEqualToString:HELPER_APP_BUNDLE_ID] &&
![launchedByAppBundleId isEqualToString:@"com.apple.loginwindow"])
{
Application_IsLaunchedByHelperApp = NO;
}
}
