Hello all,
I tried to launch a application named "abc.app" use NSTask, I write code
as follows:
NSArray * args = [[NSArray alloc] initWithObjects:@"2", nil];
[NSTask launchedTaskWithLaunchPath:@"/Users/feil/Desktop/abc.app"
arguments:args];
I always get error message:Task create for path abc.app failed.
You need to run the actual executable file, inside of the app wrapper.
Change the path to "/Users/feil/Desktop/abc.app/Contents/MacOS/abc".

Now, I'd like to retrieve the arguments in the launched application.
Ok, I can modifiy the "main(...)" function to get the arguments,
but I'd like to know if there is an other way to do this......
Any idea ?
If you're command line arguments can look like
-MyCommandLineArg Foo
then you can just use NSUserDefaults
value = [[NSUserDefaults standardUserDefaults]
stringForKey:@"MyCommandLineArg"];
if ([value isEqualToString:@"Foo"]){
/* Do stuff cuz MyCommandLineArg is == Foo */
}
This will not work if you have to pass the command line args in a very
specific way for other reasons.
else you could do
[[NSProcessInfo processInfo] arguments]
which returns an NSArray of the command line arguments and just parse them
your self.
