    To paginate ePub, you have to extensively use WebView and column layout with custom CSS. Here is a typical workflow for each chapter:

    1. Create an in-memory or off-screen WebView component with required width and height;
    2. Load a chapter HTML with injected <script src="[local path]"></script> tag;
    3. JavaScipt code should enclose the whole content into one div tag using DHTML;
    4. Also, JavaScript should inject CSS with a property column-width set for that div tag;
    5. When WebKit engine completes rendering, you receive an event in JavaScript;
    6. Once you get the event, it’s time to count how many pages is in HTML: clientWidth / width.

    Then, you can use the same technique to render ePub into UIViewController, but this time on screen. While rendering how many pages are in ePub, you may want to display a progress indicator.
