How to read and display PDF in Objective-C?

回答1:

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

回答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:
