What do you mean by "treat some views as sheets"?

Sheets are fairly easy to implement, and are documented in the Cocoa developer documentation. In particular, see the documentation for the following AppKit functions to implement simple alert sheets:

NSBeginAlertSheet
NSBeginCriticalAlertSheet
NSBeginInformationalAlertSheet


To implement more complex sheets, see the documentation for the following NSApplication methods:

-beginSheet:modalForWindow:modalDelegate:didEndSelector:contextInfo:
-endSheet:
-endSheet:returnCode:

Note that with these three methods, you'll have to use -[NSWindow orderOut:] to remove the sheet from the screen once it's ended.

Also, there's a Programming Topic on Sheets in the Cocoa developer documentation installed with the Mac OS X Developer Tools. It's always a good idea to check out the Programming Topics when trying to figure out how to use a technique in Cocoa.
