    What is the use of QLPreviewController in iOS?

    QLPreviewController class or Quick Look Preview Controller provides us facility to previewing an item. For displaying a QLPreviewController we have 2 options:
    - by pushing it into view using a UINavigationController object. OR
    - by presenting it modally, fullScreen using the presentModalViewController:animated: method of its parent class(UIViewController).

    We can use preview controller to display previews for following items:
    - Images,
    - PDF files,
    - Rich Text Format(RTF) documents,
    - MSOffice documents(Office'97 and newer),
    - iWork documents,
    - Comma-separated value(csv) files

    In iOS QLPreviewController class is available in the QuickLook.framework, so it is mandatory to import that framework for using features of QLPreviewController class.
