There is a bug that prevents setting the icon of files that already have
a custom icon, I sent in a bug fix for it but last time I looked Troy
hadn't released an update with the fix, he's a busy man. Also the class
works by creating a resource for the file and storing the icon data in
there with all correct flags set, but folders don't have resource fork.
In mac OS 9 this is done with and invisible file called 'Icon\n' pretty
sure it's a return that it ends with, OS X seems to be the same, you
might have success if instead of saving the custom icon to the folder
you specify the 'Icon\n' file instead. It would be good if IconFamily
handled this automaticly.
From your original post it seems to me what you want to do is create an
IconFamily with the iconFamilyWithIconOfFile: method passing it you
.icns file, and then apply it to your folder with the
setAsCustomIconForFile: method where you paths is "<folder
path>/Icon\n". There is no way to do this in Cocoa it's all carbon
wrapped in Cocoa.
You can change the tint of an image by simple creating a new image of
the same size, locking focus on it they drawing your original image at
(0,0) and then drawing over the image with the
NSRectFillUsingOperation(NSRect aRect, NSCompositingOperation op)
function, look at the source code example
/Developer/Examples/AppKit/CompositeLab to see what the different
operations do.

Hello!
Found some good learning code there but it does not solve my problem.
It looks like MAYBE the "saveThumbnailToIcnsFile:" action is what I am
looking for but when I try it out in the built app it does not work.
Furthermore I just want folders to be able to receive the custom icon
instead of ICNS files. Maybe if I explain more:
What will happen is first: my user will select a folder in the Finder,
then he will switch to my app (maybe have a utility panel with no hide
on deactivate command)
The user will then select an item from a pop up menu and it will be
inserted into a string with "iconlabel = [[iconlabelPopUpButton
selectedItem] tag];"
Then my app will test that string and based on the item selected it
will set the custom icon of that folder to the correct one in the app's
package.
Maybe if someone could point me to some documentation that describes
every method in detail?
Also, does any of you know how I would change the tint of an icon?
(Look in Can Combine Icons for an example)
Thanks!
Albert
