title: Adding subview to view with a PDFView as a subview
body: <p>I have a controller view. This controller has a PDFView as a subview and another subview which is like a controller to the pdf. </p>
  
  <p><img src="https://i.stack.imgur.com/vW0iJ.png" alt="image"></p>
  
  <p>The problem is that if I do the following in the controller:</p>
  
  <pre><code>self.view addSubview:pdfView];
  [self.view addSubview:pdfController];
  </code></pre>
  
  <p>The pdfController lays on the pdfView, but it will scroll with the pdf if you scroll it. I want to make pdfController view to be immobile and to just sit on the pdfView. Does anyone know how to get this behavior? </p>
