Drag and drop .app files into NSImageView and get the file path

I have an NSWindow containing and NSImageView. I want that the user can drag 'n drop a .app file (application) into the NSImageVie开发者_JS百科w, and my application see which file is dropped. Is there a way to do this (okay, I'm sure there is a way to do this -_- but which one :p )?

So much like iWeb does it with image files.

A tutorial would be nice (english or dutch).

Thanks in advance.

1. Subclass NSImageView
2. Implement NSDraggingDestination protocol
3. Register an instance of your subclass to accept your defined PBoardType
