Integration

Using PSPDFKit

PSPDFKit can be integrated with just a few lines of code,
and it comes with a rich API, which allows for complete customization.

Swift
Copyimport PSPDFKit
import PSPDFKitUI

// Create the PSPDFDocument.
// This is the container for your PDF file. It can also manage multiple files.
let documentURL = Bundle.main.url(forResource: "Document", withExtension: "pdf")!
let document = PSPDFDocument(url: documentURL)

// Create the PDF view controller. This will present and manage the PSPDFKit UI.
let pdfController = PSPDFViewController(document: document)

// Present the PDF view controller within a UINavigationController to enable the toolbar.
present(UINavigationController(rootViewController: pdfController), animated: true)
Objective-C
Copy@import PSPDFKit;
@import PSPDFKitUI;

// Create the PSPDFDocument.
// This is the container for your PDF file. It can also manage multiple files.
NSURL *documentURL = [NSBundle.mainBundle URLForResource:@"Document" withExtension:@"pdf"];
PSPDFDocument *document = [[PSPDFDocument alloc] initWithURL:documentURL];

// Create the PDF view controller. This will present and manage the PSPDFKit UI.
PSPDFViewController *pdfController = [[PSPDFViewController alloc] initWithDocument:document];

// Present the PDF view controller within a UINavigationController to enable the toolbar.
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:pdfController];
[self presentViewController:navController animated:YES completion:nil];

Swift
Copyimport PSPDFKit
import PSPDFKitUI

let documentURL = Bundle.main.url(forResource: "Document", withExtension: "pdf")!
let document = PSPDFDocument(url: documentURL)

// Use the configuration to set main PSPDFKit options.
let configuration = PSPDFConfiguration { (builder) in
    // Switch to continuous vertical scrolling.
    builder.pageTransition = .scrollContinuous
    builder.scrollDirection = .vertical
    // Disable the thumbnail bar.
    builder.thumbnailBarMode = .none
    // etc.
}

// Create the PDF view controller, passing the configuration object.
let pdfController = PSPDFViewController(document: document, configuration: configuration)

present(UINavigationController(rootViewController: pdfController), animated: true)
Objective-C
Copy@import PSPDFKit;
@import PSPDFKitUI;

NSURL *documentURL = [NSBundle.mainBundle URLForResource:@"Document" withExtension:@"pdf"];
PSPDFDocument *document = [[PSPDFDocument alloc] initWithURL:documentURL];

// Use the configuration to set main PSPDFKit options.
PSPDFConfiguration *configuration = [PSPDFConfiguration configurationWithBuilder:^(PSPDFConfigurationBuilder *builder) {
    // Switch to continuous vertical scrolling.
    builder.pageTransition = PSPDFPageTransitionScrollContinuous;
    builder.scrollDirection = PSPDFScrollDirectionVertical;
    // Disable the thumbnail bar.
    builder.thumbnailBarMode = PSPDFThumbnailBarModeNone;
    // etc.
}];

// Create the PDF view controller, passing the configuration object.
PSPDFViewController *pdfController = [[PSPDFViewController alloc] initWithDocument:document configuration:configuration];

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:pdfController];
[self presentViewController:navController animated:YES completion:nil];

Swift
Copyimport PSPDFKit

let documentURL = // PDF URL from a writable location...
let document = PSPDFDocument(url: documentURL)

// Load a graphic resource from another PDF document.
let logoURL = Bundle.main.url(forResource: "Logo", withExtension: "pdf")!

// Create a custom stamp annotation on the first page.
let stampAnnotation = PSPDFStampAnnotation()
stampAnnotation.appearanceStreamGenerator = PSPDFFileAppearanceStreamGenerator(fileURL: logoURL)
stampAnnotation.boundingBox = CGRect(x: 180.0, y: 150.0, width: 444.0, height: 500.0)
document.add([stampAnnotation])

// This is a blocking save.
document.save()
Objective-C
Copy@import PSPDFKit;

NSURL *documentURL = // PDF URL from a writable location...
PSPDFDocument *document = [[PSPDFDocument alloc] initWithURL:documentURL];

// Load a graphic resource from another PDF document.
NSURL *logoURL = [NSBundle.mainBundle URLForResource:@"Logo" withExtension:@"pdf"];

// Create a custom stamp annotation on the first page.
PSPDFStampAnnotation *stampAnnotation = [[PSPDFStampAnnotation alloc] init];
stampAnnotation.appearanceStreamGenerator = [[PSPDFFileAppearanceStreamGenerator alloc] initWithFileURL:logoURL];
stampAnnotation.boundingBox = CGRectMake(180.f, 150.f, 444.f, 500.f);
[document addAnnotations:@[stampAnnotation] options:nil];

// This is a blocking save.
[document save];
