You can do whichever you like. I tend to wander objects up and down my various controller and delegate chains as I write code because where I think I want it, I sometimes don't want it. Ask yourself this, what is this sheet most closely tied to? Is it something which is going to be used in the delegate on some kind of delegate callback? If so, you probably want the delegate to own it. Or is it something the WindowController really wants to 'own'? If that's the case then let it own it. If (in the code you posted) you're at that point in your AppDelegate then 'self', the thing you pass as owner, is the wrong type for the way you say you have your XIB configured. You need to make sure that the 'owner' is an object of the class you've told the XIB that File's Owner is; it can be what you like, but you have to be consistent. If you want it to be in your NSWindowController subclass, then for 'owner' you need to pass that window controller subclass object and the window you require will end up bound to some properly (you define) of that, then you pass [ yourWindowController thePropertyYouChose ] as the window to your sheet method. And don't forget, in your XIB .. you need to make the connection to the property in File's Owner. Oh yes it's easily said but so easily overlooked and you'll be asking why your sheet doesn't come up after you loaded the NIB and it will be because the outlet is nil because you didn't actually hook it up graphically in IB. > It's possible I shouldn't separate this, at least to do what I want to be > able to do with sheet.s In the books I've read, that's the way they've set up > objects and controllers for MVC...
