title: how to know which xib file uses the image?
body: <p>While running my project, I've got this error message.</p>
  
  <pre><code>Could not load the "bs_back_light.png" image referenced from a nib in the bundle with identifier "com.xxxxxxx.new"
  </code></pre>
  
  <p>I don't use the image file anymore, so I want to delete the image referencing in xib file. However, the project has a lot of xib files, and it is really hard to find xib file which references the image. If it is source file, I would use <strong>Find in Workspace</strong>(Shift + Command + F), but it doesn't search xib files.</p>
  
  <p>How to search the image referencing from xib(nib) files?</p>
  
  <p>I'm using Xcode Version 4.3.3 (4E3002)</p>
