title: View controller uses one nib fine but crashes with another
body: <p>I'm working on a universal app and the iPhone version works just fine. I created a new nib for iPad and set the files owner to be the viewcontroller class. The I connected all the IBOutlets and IBActions. When I run the app on an iPad (and in the iPad simulator) it crashes when I touch any of the controls. I tried setting break points in the IBActions for each but it doesn't even make it to those before the crash happens. What's going on?</p>
