Answer 1

Only way is Using the Quick Look Framework .

Use the Quick Look framework to provide previews of items that are in formats you don't handle—such as iWork or Microsoft Office . This framework affords you more control over the preview process than you get from the UIDocumentInteractionController class—including choosing whether the preview is displayed in the context of a navigation controller or modally (full screen). The primary class in this framework is QLPreviewController, which provides a specialized view for previewing an item. It relies on a delegate for mediating preview actions, and a data source for providing the preview items.

In iOS 4.2 and later, the specialized view presented by a Quick Look preview controller includes an action button with a Print item. If the controller can provide a preview of a file, it can also print it. There is no printing code for you to write.

To display a Quick Look preview controller you can use any of these options:

1. Push it into view using a UINavigationController object.
2. Present it modally, full screen, using the presentModalViewController:animated: method of its parent class, UIViewController .
3. Present a document interaction controller (as described in “Previewing and Opening Files.” The user can then invoke a Quick Look preview controller by choosing Quick Look from the document interaction controller's options menu.

A Quick Look preview controller can display previews for the following items:

Microsoft Office documents (Office '97 and newer)

iWork documents

Rich Text Format (RTF) documents

PDF files

Images

Text files whose uniform type identifier (UTI) conforms to the public.text type (see Uniform Type Identifiers Reference)

Comma-separated value (csv) files
