PDFTouch SDK

PDFTouch SDK

Released 3 years ago , Last update 1 week ago

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.

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];

F.A.Q

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.

    Hi, I am working on a app of iOS to display some documents. But now these documents include 3D pdf files, for example, a engine CAD 3D model pdf, a engine 3D PRC type pdf. I want to know if your PDF reader or viewer can be called by my app to display 3D pdfs correctly on Ipad or Iphone? Thank you very much Grid Qian
    • Kemal Taskin Publisher 5 days ago
      Hi Grid, PDFTouch SDK does not have support for 3D PDF files.

    Hello, My company is considering to purchase this SDK, but first we need to know: 1. Can I create a new one and edit existing PDF files with PDFTouch SDK? 2. In our software we need to edit some paragraph in PDF document. Is it possible with this lib (programatically, without user interaction)? Regards, Marcin
    • Kemal Taskin Publisher 1 week ago
      Hi Marcin, PDFTouch SDK does not have editing capabilities. It can only be used to view PDF files.
  • JD Johnny Delphino 2 weeks ago
    Hi, currently I'm evaluating your framework for our app in development. I have some questions you hopefully can answer: 1 If I search for a term and click the link to one of the found results in the tableview before the searching finishes my search-results/term are not saved. If I click another time into the search field I have to start over. You can try in your e.g. in your Demo with the "Developers" Document - Search for "dev" and click the first result as it appears in the tableview. Then click again in the search field -> it is empty. Is this behaviour intended? Is there a way /flag to change this? 2 If I have a view controller that conforms to the "YLSearchDelegate" protocol where do I have to assign this view controller as search-delegate? In the YLPDFViewController, YLDocument, anywhere else? If I assign my YLSearchDelegate to the delegate property of YLPDFViewController the delegation-methods are never called 3 Is there a way to open all hyperlinks (with the http:// scheme) of the PDF in the AnnotationWebview /in the App and not switch to safari. 4 If they can not be opened in the App: Is there a way to directly open them in Safari without the alert shown? Another way would be to change all links to your ylweb:// Scheme. But that would be much work to change our existing PDFs. How can I create the Matching Links that are opened correctly inside the PDFTouch Webview in InDesign? All my trials didn't work. Sorry for this bunch of questions. I hope you can help me further. Thanks in advance. Best regards, Johnny
    • Kemal Taskin Publisher 2 weeks ago
      Hi Johnny, 1) Yes, this is the intended behaviour because the search operation is very CPU/memory intensive. If the user selects a search result before the search operation is completed, the search operation will be cancelled. There's currently no flag to change this behaviour. 2) You should set your view controller as the search delegate like this: [pdfViewController.document.scanner setSearchDelegate:self]; The scanner property is an instance of YLDocumentScanner. 3) No, http:// links are opened in Safari. 4) There's currently no property to suppress the alert view. If you want to open a link in the internal browser you should use the following format: "ylweb://yakamozlabs.com?modal=1". If you don't supply the modal parameter the web page will be embedded on the PDF page as a subview. PDFTouch SDK comes with the complete source code so it's pretty easy and convenient to customize it to your needs. Best, Kemal
    • JD Johnny Delphino 2 weeks ago
      Thanks for the fast reply Kemal, 4) Links in Style "ylweb://yakamozlabs.com?modal=1" should be sufficient. I tested it and works. Is there a way to customize the web view (back/forward-buttons, etc)? Will your URL-Scheme work with more complex links, like: https://www.google.de/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=javascript%20string%20replace >PDFTouch SDK comes with the complete source code so it's pretty easy and convenient to customize it to your needs. But that's not the case when I only purchase the Framework-Binary for 999$? Thank you very much
    • Kemal Taskin Publisher 2 weeks ago
      4) Yes, it will also work with more complex URLs. Customizing the internal browser is only possible if you have access to the source code. All licenses except the "Single App Binary ($999)" license come with the source code.
