Xcode WKWebView code to allow WebView to process popups - ios

Question

I am totally new to Xcode and the syntax is totally escaping me.
I have one thing left to do and then I've achieved what I need to within Xcode.
I need to insert a function that allows the WebView to process popups, but I have no idea where to begin inserting the code.
This is the current code:
import UIKit
import WebKit
class ViewController: UIViewController, WKNavigationDelegate {
override func viewDidLoad() {
super.viewDidLoad()
let webView = WKWebView()
let htmlPath = Bundle.main.path(forResource: "index", ofType: "html")
let folderPath = Bundle.main.bundlePath
let baseUrl = URL(fileURLWithPath: folderPath, isDirectory: true)
do {
let htmlString = try NSString(contentsOfFile: htmlPath!, encoding: String.Encoding.utf8.rawValue)
webView.loadHTMLString(htmlString as String, baseURL: baseUrl)
} catch {
// catch error
}
webView.navigationDelegate = self
view = webView
}
}
How do I edit this in order to allow popups?
Please remember that I don't know how to add the solutions that I'm finding, so please show me where to insert the snippet as well.

Try this code, hope it helps!
class ViewController: UIViewController {
var webView: WKWebView!
var popupWebView: WKWebView?
var urlPath: String = "WEBSITE_URL"
override func viewDidLoad() {
super.viewDidLoad()
setupWebView()
loadWebView()
}
//MARK: Setting up webView
func setupWebView() {
let preferences = WKPreferences()
preferences.javaScriptEnabled = true
preferences.javaScriptCanOpenWindowsAutomatically = true
let configuration = WKWebViewConfiguration()
configuration.preferences = preferences
webView = WKWebView(frame: view.bounds, configuration: configuration)
webView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
webView.uiDelegate = self
webView.navigationDelegate = self
view.addSubview(webView)
}
func loadWebView() {
if let url = URL(string: urlPath) {
let urlRequest = URLRequest(url: url)
webView.load(urlRequest)
}
}
}
extension ViewController: WKUIDelegate {
//MARK: Creating new webView for popup
func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {
popupWebView = WKWebView(frame: view.bounds, configuration: configuration)
popupWebView!.autoresizingMask = [.flexibleWidth, .flexibleHeight]
popupWebView!.navigationDelegate = self
popupWebView!.uiDelegate = self
view.addSubview(popupWebView!)
return popupWebView!
}
//MARK: To close popup
func webViewDidClose(_ webView: WKWebView) {
if webView == popupWebView {
popupWebView?.removeFromSuperview()
popupWebView = nil
}
}
}
}
