Re: nsdocument/nsapp delegate question

Where I'm stuck is that I need find out in applicationWillFinishLaunching: whether or not the app was launched via a document or via the app. But, application:openFile: is not sent until after applicationWillFinishLaunching: and by the time applicationDidFinishLaunching: is sent, there is already an untitled document opened automatically. How else can I check how the app was launched via a document?

I think you can get the behaviour you describe just by implementing -applicationShouldOpenUntitledFile: in your app delegate. That shouldn't get called until the app is finished launching.

Thanks- at first I didn't think that -applicationShouldOpenUntitledFile: was the answer, however with some judicious setting of flags to see if the app is finishing launching, and if another document has been loaded already, I've got it working:

- (BOOL)applicationShouldOpenUntitledFile:(NSApplication *)sender
{
if(! launching) // don't interfere w/ normal use of untitled files
return YES;
if((! hasOpenedDocument) &&
(! [[NSUserDefaults standardUserDefaults]
boolForKey:@"loadPreviousDocumentOnStartup"]))
{
return YES;
}
return NO;
}

This works, but my cocoa sense expected to find a method like [NSApp wasLaunchedByDocumentIcon] or somesuch.
