I am using Quartz to display a PDF if my iPad app rather than a webview as I dont link the borders and drop shadow effects the webview adds.
Can I still use embedded links in the PDFs? If so do I need to do anything special or will they just work?

I have an IPhone application in which i need to have pdf pages view like a book.Is there any way to load a PDF document in a UIWebview so that it can scroll horizontally instead of vertically? Is it possible?If so some one give me the way to do this .Can someone help me?
You cannot do that using a UIWebView neither a QLPreviewController. They do what they do and are no customizable. They use a vertical scroll to present pages from a pdf document.
Your only chance is to open PDF with Quartz framework and access to each page, there are good apple tutorials for this topic. Then you can present separate pages as you want in a UIScrollView with a UIPageControl, much better, a UIPageViewController.
I found an open project. i think it's use full

I've written an iPhone App that downloads a PDF. I want to present this PDF to the user but not draw it in an UIView in my App itself. Is this even possible?
You can use Quartz APIs. CGContextDrawPDFPage and the related samples would be a nudge in the right direction.
UIWebView is another approach. As WTP noted below: UIWebView automatically does pagination and allows the user to scroll, zoom and select content.
UIWebView is the typical 'free' approach, but you may need Quartz APIs if you have special needs.
i need to create a pdf reader with an overview page showing thumbnails of the pdf. like with the pdfs in ibooks.
what would be the best approach for that?
i am thinking about using a uiscrollview and placing uiviews with tiledlayers for pdf rendering? how can i best determine which view is visible and recycle them accordingly?
thanks

Apple has sample code to get a PDF thumbnail on their developer site. I believe it is in the Quartz2d Programming Guide (unfortunately the site is down for me at the minute so I can't confirm).
I'm working on a mobile-optimized version of a client site that contains many HTML5 video tags. When viewing on the iPhone it's displaying the default play button watermark. Is it possible to customize this icon?
I don't think you can do this in the HTML, because the play icon you're seeing is in fact an (undocumented) UIButton subclass that's laid on-top of the webpage. It's not an HTML element, it's a UIKit one.
I have messed around in the past with modifying this button, but you need to perform various dodgy operations on a UIWebView from Objective-C, not HTML, so it's probably not much help to you (even if it was, it's all undocumented so not suitable for production use anyway).
I have a strange issue in phonegap framework. I want to display PDF file in my application, when I am trying to add PDF file with iFrame tag it doesn't show a PDF with horizontal scroll and with a big zoom size. so getting out of screen.
I tried by another way using embed tag, its also having same problem with addition to that its showing PDF for only first time in the application.
If anybody know how to display a PDF in phonegap with specified zoom level or with scroll bar. Above code is working fine in iPhone mobile safari, but not in phonegap. Any Idea?
Thanks.
To display pdf in phonegap,
have lots of trouble,
but best solution so far,is to used ChildBrowser Plugin for phonegap here is the link-
https://github.com/purplecabbage/phonegap-plugins/tree/master/iPhone/ChildBrowser
this will help you to call child native uiwebview in your application(only for iphone),
so you can easily enjoy pinch zoom feature
Using Phonegap you'll have only one UIWebView so probably the best idea is to open the pdf as a new object link using rel=external
Other suggestion is look at the view-port size, maybe you'll have to increase it's size to allow the pinch and zoom.
