How to display a PDF in Objective-C? [closed]

Answer 1

If you just want to display it, the easiest way is to load it in a UIWebView.

Answer 2

If you want to solely read and display PDFs to users, as the Mail app does on your iOS device with all the scrolling and zooming done for you, then I would use a UIDocumentInteractionController.

You'll find some useful code in one of my recent questions, here:

UIDocumentInteractionController crashing upon exit

Hope this helps.

Answer 3

the easiset way is with the UIDocumentInteractionController

Drawback: you need a local file-url
