Using the Mail.app UI look in your own xcode project?

The smooth metal look is actually more iTunes than Mail... however, the Mail look is available; just check the "use unified toolbar"* checkbox in the window inspector in IB.


*something like that, anyway

 

Doable, but requires a lot of custom UI code.

Oh, you only wanted the unified look? If just that, then that's just a checkbox in IB like Catfish_Man said. But if you want to spice it up, check out those links. If you don't care, then that's fine too

 

It only works with a) a toolbar and b) 10.4+

 

Read up on NSToolbar.

 

You can have the NSToolbar delegate code in the same controller.h as the other stuff. Or you could put it in a category if you were feeling flash.

Please don't take this the wrong way but I get the feeling you're trying to run before you can walk. I'd strongly recommend getting the Hillegass book ( http://www.bignerdranch.com/products/cocoa1.shtml ) and learning a bit of the basics.
