var documentInteractionController: UIDocumentInteractionController!

@IBAction func openDocument(sender: UIButton) {
  let URL: NSURL = NSBundle.mainBundle().URLForResource("yourPDF", withExtension: "pdf")!

    if (URL != "") {
        // Initialize Document Interaction Controller
        self.documentInteractionController = UIDocumentInteractionController(URL: URL)

        // Configure Document Interaction Controller
        self.documentInteractionController.delegate = self

        // Present Open In Menu
        self.documentInteractionController.presentOptionsMenuFromRect(sender.frame, inView: self.view, animated: true)
            //presentOpenInMenuFromRect
    }
}

// UIDocumentInteractionControllerDelegate
func documentInteractionControllerViewControllerForPreview(controller: UIDocumentInteractionController) -> UIViewController {
    return self
}
