Suggested save name of an untitled NSDocument

Question

Is there a way to suggest a file name for the initial save dialog (of an untitled document) to use for a document in the nsdocument framework?

Answer 1

In OSX 10.8 you can add this method

- (NSString *)defaultDraftName

Answer 2

In Mac OS X v10.7 and later:

- (void)setDisplayName:(NSString *)displayNameOrNil

v10.6, override in your NSDocument subclass:

- (BOOL)prepareSavePanel:(NSSavePanel *)savePanel
{
    if( [savePanel.nameFieldStringValue isEqualToString:@"Untitled"] )
        [savePanel setNameFieldStringValue:@"hello"];

    return [super prepareSavePanel:savePanel];
}

In fact the default implementation is empty and returns YES so could just do that.

Not sure about testing for "Untitled" though, won't work if they have already saved as "Untitled" and want to keep that name, and maybe it won't localise, so maybe set a flag in

- (id)initWithType:(NSString *)type error:(NSError **)error

or is there already one?
