Why don't you use QLPreviewController or UIDocumentInteractionController?

Now in your case you can do it by using webView:

let req = NSURLRequest(url: pdf) //pdf is your pdf path
let webView = UIWebView(frame: CGRect(x:0,y:0,width:self.view.frame.size.width,height: self.view.frame.size.height-40)) //Adjust view area here
webView.loadRequest(req as URLRequest)
self.view.addSubview(webView)
