How to add UIActivityIndicatorView to WKWebView? - ios

Question

I'm new to Swift and I need some help implementing the UIActivityInidicatorView to WKWebView. It should appear while the webpage is loading and disappear when the website finished loading.
Here is my code so far:
import UIKit
import WebKit
class ViewController: UIViewController {
#IBOutlet weak var webView: WKWebView!
override func viewDidLoad() {
super.viewDidLoad()
let myURL = URL(string: "https://www.google.com")
let myRequest = URLRequest(url: myURL!)
webView.load(myRequest)
}
}

Answer 1

import UIKit
import WebKit
class ViewController: UIViewController, WKNavigationDelegate, WKUIDelegate {
var webView: WKWebView!
var activityIndicator: UIActivityIndicatorView!
override func viewDidLoad() {
webView = WKWebView(frame: CGRect.zero)
webView.navigationDelegate = self
webView.uiDelegate = self
view.addSubview(webView)
activityIndicator = UIActivityIndicatorView()
activityIndicator.center = self.view.center
activityIndicator.hidesWhenStopped = true
activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.gray
view.addSubview(activityIndicator)
webView.load(URLRequest(url: URL(string: "http://google.com")!))
}
func showActivityIndicator(show: Bool) {
if show {
activityIndicator.startAnimating()
} else {
activityIndicator.stopAnimating()
}
}
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
showActivityIndicator(show: false)
}
func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {
showActivityIndicator(show: true)
}
func webView(_ webView: WKWebView, didFail navigation: WKNavigation!, withError error: Error) {
showActivityIndicator(show: false)
}
}

Answer 2

I finally got it working like this:
import UIKit
import WebKit
class ViewController: UIViewController, WKNavigationDelegate {
#IBOutlet weak var webView: WKWebView!
#IBOutlet weak var ActivityIndicator: UIActivityIndicatorView!
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
ActivityIndicator.stopAnimating()
}
override func viewDidLoad() {
super.viewDidLoad()
let myURL = URL(string: "https://www.google.com/")
let myRequest = URLRequest(url: myURL!)
webView.navigationDelegate = self
webView.load(myRequest)
}
}
