title: xcode iphone project and ipad project into universal app
body: <p>If I have a project that was written for iphone and a project written for ipad. Is there a recommended way to combine them into a universal app?</p>
  
  <p>My understanding is that you would take the existing app (iphone project) and convert it to a universal app then rename the classes to class_iphone, class_ipad etc.</p>
  
  <p>The process of coverting includes xcode generating a new MainWindow nib for the ipad and other related files...  But this sound painful to go into the project and duplicate the files etc..</p>
  
  <p>please advise.</p>
