adding options to IKSaveOptions?

Question

I have an ImageKit program that needs to be able to save images, so I'm using the IKSaveOptions accessory view, to allow the user to choose a file type, etc.

However, I want to remove some of the options, and add a checkbox to the panel for TIFFs. Alternatively, I want to add a type of file. However I can't figure out how to do this. I assume I'm going to have to subclass off of IKSaveOptions and over-ride something, but I can't find any sample code or documentation that tells me how to do this.

ETA: In particular, I need to be able to allow the user to distinguish between multi-page tiff, and a bunch of single-page tiffs with a page-number appended.

ETA: So, SO is telling me "I have only a few hours before the bounty expires so I should choose an answer" But ... there are no answers! (You'd think that SO would be smart enough to see that, but oh well B-)

Answer 1

IKSaveOptions is inherited from NSObject. Real accessory view is built internally and is not accessible with public API:

@interface IKSaveOptions : NSObject
{
@private
    void *  _privateData;
    id      _saveOptionsView;
}

So your best bet is to build your own save dialog accessory view with blackjack and hookers. You can start with NSView custom view in interface builder. Then it is simply:

NSSavePanel *saveDialog = [NSSavePanel savePanel];
[saveDialog setAccessoryView:mySaveAccessoryView];
