Does XIB always need a view controller?

If I do an interface in IB must I always need a base UIViewController or can I just skip straight to a UIView ?

As of now I'm doing all my design in obj-c which makes for a bit more busy work.

If I have to use a UIViewController is there anyway to suck the UIView out of it if that's all I want?

I just want to be able to pull out static layouts from XIB instead of putting them together in obj-c.

Any suggestions are appreciated!

No, you don't need to associate a UIViewController with a XIB.

First, do not add a view controller to the XIB. Then, you'd often use NSNib or UINib APIs to access the top level objects of the nib -- so you can avoid a view controller and set up any structure you'd like in the NIB editor, and programmatically access the objects in the NIB as needed.

No, you don't need a UIViewController if it doesn't serve your needs.

After you have initialized a UINib, use its:

-instantiateWithOwner:options:

to access the nib contents. Make the nib's root object be a UIView (or subclass thereof). If you plan on making connections to File's Owner you will need to set File's Owner to a context-appropriate class.

UIViewController has that handy initWithNib: bundle: method that makes everything so easy, but there are also ways to get objects from xibs via:

NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"WhateverItsNamed" owner:self options:nil];

(and the nib array here contains objects which correspond to whatever objects are stored in the XIB file).

In iOS 5, XIB are not recommended to be used anymore, you should use a storyboard instead. And to simply answer your question, every top level view requires a view controller to be responsible for it.

All sub views can be an outlet in your view controller and be handled from there.
