• 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>

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

Sample Usage

1. 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];

2. 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];
