A fast and customizable Objective-C framework for reading and rendering PDF files in iPhone and iPad apps. Build PDF reader apps or use it as a PDF viewer in your existing apps.

Powerful Objective-C PDF Rendering for iPhone and iPad apps

Getting PDF rendering right on the iOS platform is difficult and time consuming. Memory constraints and slow CPU conditions make it very hard to achieve fast PDF rendering. The PDF Touch SDK is the result of months of development time and years of optimization, providing you with a mature and performant solution for adding PDF capabilities to your iPhone or iPad app.

PDFTouch SDK provides a robust framework that is easy to use and customize to your needs. With just a couple of lines of code you can create a PDF view controller and display it in your app. The user interface is very similar to the iBooks app and also features a grid display for page thumbnails. For more details please refer to the Features section below.

Code Documentation

All public classes of PDFTouch SDK are documented using appledoc. See the documentation for further information.


The source code of PDFTouch SDK is developed on Xcode 6.1 with iOS Base SDK 8.1. PDFTouch SDK works on a deployment target of iOS 7 or greater on armv7, armv7s, arm64 and can be used in ARC and non-ARC projects.


PDFTouch SDK can be integrated in two ways into your app.

1. Add the binary PDFTouch.framework

  • Drag PDFTouch.framework into the "Frameworks" group of your Xcode project.
  • Add the required libraries as shown in the screenshot below.
  • Add PDFTouch.bundle to your projects resources as shown in the screenshot below.
  • Open the Build Settings tab and apply the following changes:
    • Other Linker Flags -> -all_load -ObjC
  • Add the following import statement everywhere you want to use PDFTouch SDK: #import <PDFTouch/PDFTouch.h> Binary

2. Add PDFTouch.xcodeproj as a dependency

  • Copy the whole PDFTouch folder into your project's root folder.
  • Drag PDFTouch.xcodeproj into the "Frameworks" group of your Xcode project.
  • Add PDFTouch as a target dependency.
  • Add the required libraries as shown in the screenshot below.
  • Add PDFTouch.bundle to your projects resources as shown in the screenshot below.
  • Open the Build Settings tab and apply the following changes:
    • Other Linker Flags -> -all_load -ObjC
    • Add the following paths to "Header Search Paths":
      • "PDFTouch/**"
  • Add the following import statement everywhere you want to use PDFTouch SDK: #import "PDFTouch.h" Source

Sample Usage

1. Set your license key in the app delegate. You can request your license key on this page: http://yakamozlabs.com/license-key.

[[YLPDFTouch sharedInstance] setLicenseKey:@"your-license-key"];

2. Create a YLDocument instance for the PDF file you want to display.

NSString *path = [[NSBundle mainBundle] PathForResource:@"Developers" withExtension:@"pdf"];
YLDocument *document = [[[YLDocument alloc] initWithFilePath:url] autorelease];

3. Create a YLPDFViewController instance and present it as a modal or child view controller.

YLPDFViewController *v = [[YLPDFViewController alloc] initWithDocument:document];
[v setDocumentMode:YLDocumentModeDouble];
[v setDocumentLead:YLDocumentLeadRight];
[v setPageCurlEnabled:YES];
[v setModalPresentationStyle:UIModalPresentationFullScreen];
[v setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
[self.navigationController presentModalViewController:v animated:YES];
[v release];


I am developing an application for a customer. Which license should I use? The single app license cannot be used for building applications for your customer since the license cannot be sub-licensed nor transferred to your customer. In that case you will either have to purchase a developer license or have your customer purchase a single app license which you can then use to develop the application. However purchasing the Developer license will be a valuable investment which will pay off if you'll use it in more than one client project.

What's the difference between the Developer and Enterprise license? Both the Developer and Enterprise license allow usage in unlimited number of apps. The only difference is that the Enterprise license doesn't require license key activation for each individual app. This is especially useful if you offer a product that generates custom iOS apps on demand.

Is it possible to upgrade between different licenses? An upgrade is possible. Contact us for more information or browse to the "My Purchases" section to upgrade your license.

My license is expired. What does this mean? Each of our licenses include 1 year free updates. If you want to keep receiving new updates and support you can do so by paying a renewal fee which is about 25% of the current license price. If you don't renew your license you can still keep using the version you have on hand. It will keep working without any restrictions.

  • A Amanda 1 day ago
    Hello, I'm using the API scrollToPage. It works fine on my iPad and iPhone using iOS 8 and up. But it is not working for my iPad running iOS 7.1.1. The thumbnails show the page it should be on, but the actual page is always page 1. Is this a known issue? Is there a workaround?
    • Kemal Taskin Publisher 7 hours ago
      Hi Amanda, I tested on an iPhone 4 device running iOS 7.1.2 but couldn't reproduce your issue. Are you calling the "scrollToPage" method after the "didDisplayDocument" delegate method is called?
    • A Amanda 4 hours ago
      No, i was calling it in the "willDisplayDocument" delegate. i changed to "didDisplayDocument" and its working, although you can see it go from page 1 to the page specified. Is there a better way to do this so when opening the document it will just display a specific page?
  • YL yonathan liang 1 month ago
    Hi, Kemal my company is planning to find suitable framework to be used in our magazine app. i have a few question if you don't mind 1. can PDFTouchSDK plays embedded video / sound inside PDF? 2. can we customize the viewer so that it scrolls vertically and then horizontally as well ( having multiple pdf, scrolls vertically for pdf content and horizontally to switch to next / previous pdf ) thanks for your answer
    • YL yonathan liang 1 month ago
      i forgot to mention that the pdf containing embedded video is made with indesign
    • Kemal Taskin Publisher 1 month ago
      Hi Yonathan, 1. PDFTouch SDK does not support embedded audio/video. Multimedia is supported by using custom link annotations which point to external video/audio resources. You can have a look at the "pdftouch.pdf" in the demo app to see this in action. 2. This is not supported. PDFTouch SDK with the complete source code so implementing this feature yourself is possible but it's of course not that straightforward.
  • CK Chaitanya Kulkarni 1 month ago
    Hi Team, I've downloaded a sample for PDFTouch SDK iOS , but could not find the functionality to add/view annotations. Could you please let me know if adding/viewing custom annotations and custom views will be possible by using this framework? Regards, Chaitanya
    • Kemal Taskin Publisher 1 month ago
      Hi Chaitanya, PDFTouch SDK does not support interactive annotation editing. Only embedded custom link annotations are supported to display audio, video, web pages and maps. Please have a look at the "pdftouch.pdf" file for a sample. You can also implement the YLPDFViewControllerDataSource protocol to supply custom UIViews to be displayed on a particular PDF page.
