Problem setting autosizing in interface builder

iphone interface-builder autoresizingmask

I have two viewControllers, one is a subclass of UIViewController (autoresizes correctly), the other one is a subclass of a subclass of UIViewController.
I did a layout in Interface Builder, I tested my code in the Simulator and everything works as expected. But if I rotate the device my views don't resize.
So I went back to Interface Builder and found out that I cannot change the Resizing property of the "root"-UIView. So I opened another file and the resizing property is fixed there, too. But it is set to resizing in both direction. This is the behavior I want.

How can I change the autoresizing of the top UIView so it does what I want?
There are not so many subviews that it is impossible to start again from scratch, but I don't want to do this.

I ran into this before and it was incredibly frustrating. It turns out that when you have Simulated User Interface Elements turned on then you can't change the struts and springs like you want.

Go to Attributes tab (Cmd-1) and make sure that Status Bar, Top Bar, Bottom Bar, and Split View are all set to "Unspecified." Then go back to the Size tab (Cmd-3) and you'll be able to click the lines and changes your Struts and Springs. Then finally you can go back to Cmd-1 and turn those simulated elements back on.
