Go for option #1, use a "custom drag type" (in your case ships) to
pasteboard.
aha ok understood that part. I think I know how to do it, shouldn't be
different form registering a tiff representation of an image just
register the NSData of the custom object no?
You could update the pasteboard with the array of dictionary
objects, the dictionary could hold the image/link to image and an
identifier
field for the same.
didn't get that part good... :s, if I put in the pasteboard custom
objetcs (in my case ships) each Ship has an image associated with so
in my destination when I read the pasteboard I can get the ship, and
know exactly which instance of ship is? for example, a carrier or a
frigate or destroyer and so on. I design my model having a super class
Ship, and sub classes of Ship, carrier frigate and so on.
Thanks for your help

Hello.
I have in a view images of ships, and Im able to drag them to
another view
which is the sea board, now, what is better, to create the objects
of the
ships in the "shipsviewcontainer" and set the object in the
Pasteboard, or,
just have representative images in the "shipsviewcontainer" of each
ship,
and once dragged to the sea create the instances of the ship that
the images
represent. If the last one is correct Iw as thinking if how to
know which
Ship Object the images that is being dragged represents, (maybe by
image
Size? ) I dunno what do you think its better to do, if I explain my
self
good.
Thanks
