title: View 3D PDF on iOS using objective-c
body: <p>I have at hand a 3D PDF export using AUTOCAD, has some way to view this file in iOS?</p>
  
  <p>Note that do not want to simply display a common PDF, I want to display a 3D object that is in it.</p>
  
  <p>Any solution with other file formats like 3drw is already of great help.</p>
  
  <p><strong>Edit:</strong> </p>

    <p>Note: I do not mean the applications that are in the apple store, what
    I need is a way to implement the code as necessary to integrate it
    into the app I'm working on.</p>
