PDFTouch SDK is already a solid framework that has all the basic needs for rendering PDF pages very fast. But we want to offer more than that. By purchasing the initial version of PDFTouch SDK you get the opportunity to be part of the future of this product. You'll be the one who decides which features will be implemented first or request new features.

By purchasing the initial version you'll also benefit from the %50 price cut and get all future updates for free. As new features are added the price of PDFTouch SDK will increase over time.

Here's an overview of the product roadmap that we have in mind:

• Annotations support
  • Page links
  • Web links
• Interactive elements
  • Video
  • Audio
  • Image gallery
  • Embedded web pages
  • Custom overlays
• Page-curl transition support
• Bookmark support
• Double-page support

• Fast multithreaded PDF rendering using Grand Central Dispatch.
• Highly optimized caching algorithm.
• Offline pre-rendering of pdf pages at different sizes integrated with the caching system.
• Thumbnail grid display.
• Pinch to zoom.
• Double tap to zoom in and out.
• Text search and highlighting.
• Outline view (TOC).
• Retina Display ready.
• Optimized for both the iPhone and iPad.
• Includes a demo Xcode project demonstrating the common usage of the SDK's features.

The following system frameworks are required by the PDFTouch SDK:

• Foundation.framework
• UIKit.framework
• CoreGraphics.framework
• QuartzCore.framework

PDFTouch SDK requires a base SDK setting of iOS 4.0.

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

NSURL *url = [[NSBundle mainBundle] URLForResource:@"Developers" withExtension:@"pdf"];
YLDocument *document = [[[YLDocument alloc] initWithURL:url] autorelease];

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

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

• Complete source code of PDFTouch SDK.
• Demo Xcode project.
• Documentation with integration instructions.
