Update

If you’re using Bundler, you can simply add gem ‘pspdfkit’ to your Gemfile. See more on https://github.com/tmeinlschmidt/rm-pspdfkit

As I’ve started using this famous framework, I’d like to use it in my rubymotion application. So, there’s my setup to include this fmw in rubymotion project

• extract PSPDFKit anywhere
• create directory vendor  in your RM project
• create symbolic link from your unzipped PSPDFKit to vendor/PSPDFKit.framework

cd vendor
ln -s ../../pdf/Products/PSPDFKit.embeddedframework/PSPDFKit.framework ./
cd ../resources
ln -s ../../pdf/Products/PSPDFKit.embeddedframework/Resources/PSPDFKit.bundle ./

and modify Rakefile accordingly

app.vendor_project('vendor/PSPDFKit.framework', :static, products: ['PSPDFKit'], headers_dir: 'Headers')

app.libs << '/usr/lib/libz.1.1.3.dylib'

app.frameworks += %w(MessageUI AssetsLibrary MediaPlayer PSPDFKit)

try rake , it should link and start simulator.

Next step

Add some PDF file into your app resources  folder.

And then you can try to modify app/app_delegate.rb  with simple example:

class AppDelegate
  def application(application, didFinishLaunchingWithOptions:launchOptions)

    documentURL = NSBundle.mainBundle.resourceURL.URLByAppendingPathComponent "DevelopersGuide.pdf"
    @document = PSPDFDocument.PDFDocumentWithURL documentURL

    pdfController = PSPDFViewController.alloc.initWithDocument @document
    navController = UINavigationController.alloc.initWithRootViewController pdfController

    @window = UIWindow.alloc.initWithFrame(UIScreen.mainScreen.bounds)
    @window.makeKeyAndVisible

    @window.rootViewController = navController
  end
end
