I'm trying to figure out how to save a WebView to a PDF and totally stuck, would really appreciate some help?
I'm doing this in Cocoa & Swift on OSX, here's my code so far:
import Cocoa
import WebKit
class ViewController: NSViewController {
override func loadView() {
super.loadView()
}
override func viewDidLoad() {
super.viewDidLoad()
loadHTMLString()
}
func loadHTMLString() {
let webView = WKWebView(frame: self.view.frame)
webView.loadHTMLString("<html><body><p>Hello, World!</p></body></html>", baseURL: nil)
self.view.addSubview(webView)
createPDFFromView(webView, saveToDocumentWithFileName: "test.pdf")
}
func createPDFFromView(view: NSView, saveToDocumentWithFileName fileName: String) {
let pdfData = view.dataWithPDFInsideRect(view.bounds)
if let documentDirectories = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).first {
let documentsFileName = documentDirectories + "/" + fileName
debugPrint(documentsFileName)
pdfData.writeToFile(documentsFileName, atomically: false)
}
}
}
It's pretty simple, what I'm doing is creating a WebView and writing some basic html content to it which renders this:
And then takes the view and saves it to a PDF file but that comes out blank:
I've tried grabbing the contents from the webView and View but no joy.
I've found a similar problem here How to take a screenshot when a webview finished rending regarding saving the webview to an image, but so far no luck with an OSX Solution.
Could it be something to do with the document dimensions?
or that the contents is in a subview?
maybe if you capture the View you can't capture the SubView?
Any ideas?
