title: Changing to landscape in interface builder. Xcode 4 (iOS)
body: <p>I'm working on an iPad app that's going to be in landscape. But how I change so the window in interface builder is in landscape? I remember in the old Interface Builder I just needed to click on an arrow and it switched to landscape. </p>
  
  <p>I'm using Xcode 4.</p>
  
  <p>Thank you in advance! :)</p>
