title: Interface Builder - Xcode link broken with iPad-converted xib
body: <p>In porting my app to a universal iPhone / iPad app, the xibs I created by using Interface Builder's "Create iPad Version" will not link to the project properly: They don't pick up on classes and images from the project file.</p>
  
  <p>IB tells me that "there is no xcode project associated with this document" with a gray light in the status bar. Yet the xib is in the project, was launched by double-clicking in xcode, and both are open. The old xibs work fine though. I don't understand what could be causing this.</p>

  <p>So, my question is, how do I restore the link?</p>
