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.

    I see the PDFTouch SDK supports annotations, but it doesn't specifically call-out supporting hand drawn annotations. Are those supported?
  • K Kamal 4 weeks ago
    Hi Kemal, I am using PDFTouch as a plugin in my app. I want to add a feature where the PDF document opens up at a specify section (not just specific page) of the document which I can route by using some bookmark. Can you guide me on this? Which method and which class takes care of that?
    • Kemal Taskin Publisher 4 weeks ago
      Hi Kamal, There are methods in YLPDFViewController to add/remove bookmarks and go to a specific page. However there's no feature to open a document at a specific page. This will be added in the next update.

    am developing an app, similar to Plangrid with regards to the annotations on pdf drawings. This is a very small aspect of the app but extremely important since construction revolves around the drawings. PDF requirements: Form input (not creation) Export Mark-up to csv Export photos on sheets with unit # as a reference (similar to creating spaces in Bluebeam, so when you export to csv the photo will be tied to a specific are/unit# doality.com) Annotation Searchable text OCR for finding and tagging sheet number and title of page. I would like this to be more dynamic than Plangrids measuring length, square feet Turn all mark-up on/off for clean viewing of sheet Creating issues and exporting them to csv file What is the cost for something like this, is it a monthly cost or lump sum?
    • Kemal Taskin Publisher 1 month ago
      Hi Ed, PDFTouch SDK is not suited for a project like this. Our SDK can only be used to display PDF files in iOS apps. Advanced features like adding annotations, OCR and exporting data is not supported.
    • MB Mark Baker 1 week ago
      Kemal, it says on the front page that you support annotations. Is it the type of annotations that you don't support.
    • Kemal Taskin Publisher 1 week ago
      Hi Mark, Only link annotations with custom schemes for multimedia are supported. These link annotations should be prepared with a PDF editor. PDFTouch SDK does not support annotation editing.
