Re: Simple menu-action question

I'm not sure if using Core Data would make a difference, but I'd just do this by responding to the menu command by putting up an NSOpenPanel then processing the filename it returns appropriately. I don't think there's any magic "proper" way to do this within the document architecture, except for...

Just list the file types (UTIs) that you can open in your info plist and map them to different NSDocument subclasses (if indeed a different document type is used for each different file type) or map different UTIs to the same class and differentiate the file type passed in the document's -readFromURL:ofType:error: method. This latter approach means you don't even need an "Import" menu, it just integrates into the existing Open file menu, which is more user friendly in my book - it "just works" rather than the user having to worry about what "Import" really means and whether, why and when they need to use it.

In the mishmash of Cocoa tutorials and other docs I've read, I never seem to be led through the fundamentals. With Cocoa doing so much basic stuff for me, and Xcode stationery doing a bunch more, a few things seem to fall through the cracks.

I have a pretty straightforward document application (using Core Data). I want to add an "Import" command to the File menu. What's the right way to go about this? I figure it's very similar to how Open works, but since so much of Open is already implemented by the base classes, etc, it's hard to know how to duplicate it.

Any suggestions on an example to study? Thanks!
