My goal is to replace an existing setting in the NSArgumentDomain, so
storing the setting in the application domain isn't good enough as
NSArgumentDomain takes precedence over the application defaults. The
docs only talk about setting NSArgumentDomain args from the
command-line, but since they are passed to NSApplicationMain I figured
I could also set them programmatically somehow.
That seems like a peculiar goal. If you don't want to know what was
really passed on the command line, why perform a query that returns
what is passed on the command line? As suggested, just put the data
you're interested in somewhere else and look it up from there.
In your original email, the argument list you set up wasn't
constructed in a way which would have affected NSArgumentDomain.
Perhaps that was just for illustration purposes, but you would need
something like { arg1, "-someDefaultKey", "theValue", NULL }. Note
the leading dash on the key.
You can also try replacing the contents of the NSArgumentDomain in the
shared user defaults object by doing:
NSDictionary* myValues = [NSDictionary dictionaryWith...];
[[NSUserDefaults sharedUserDefaults]
removeVolatileDomainForName:NSArgumentDomain];
[[NSUserDefaults sharedUserDefaults] setVolatileDomain:myValues
forName:NSArgumentDomain];
This will only affect the shared user defaults object. Code which
allocates and initializes its own NSUserDefaults object presumably
won't see the same contents. Also, an invocation of +[NSUserDefaults
resetStandardUserDefaults] will undo that replacement.
