Я проверил ваш новый URL, и он работает отлично.Попробуйте использовать ниже код:
import UIKit
import WebKit
class WebViewController: UIViewController {
let webView: WKWebView = {
let v = WKWebView()
return v
}()
lazy var backButton: UIButton = {
let v = UIButton()
v.layer.cornerRadius = 5
v.clipsToBounds = true
v.backgroundColor = UIColor.black.withAlphaComponent(0.5)
v.setTitle("<", for: .normal)
v.setTitleColor(.white, for: .normal)
return v
}()
var url: String?
var activityIndicator: UIActivityIndicatorView?
func setupUI(){
view.backgroundColor = .black
activityIndicator = UIActivityIndicatorView(activityIndicatorStyle: .gray)
activityIndicator?.center = self.view.center
[webView,backButton,activityIndicator!].forEach{view.addSubview($0)}
webView.fillSuperView()
if #available(iOS 11.0, *) {
backButton.anchor(top: view.safeAreaLayoutGuide.topAnchor, left: view.leadingAnchor, bottom: nil, right: nil, size: .init(width: 30, height: 30), padding: .init(top: 8, left: 20, bottom: 0, right: 0))
} else {
backButton.anchor(top: topLayoutGuide.bottomAnchor, left: view.leadingAnchor, bottom: nil, right: nil, size: .init(width: 30, height: 30), padding: .init(top: 8, left: 20, bottom: 0, right: 0))
}
}
override func viewDidLoad() {
super.viewDidLoad()
setupUI()
backButton.addTarget(self, action: #selector(didSelect(_:)), for: .touchUpInside)
}
@objc func didSelect(_ sender: UIView){
switch sender {
case backButton:
navigationController?.popViewController(animated: true)
default:
break
}
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
webView.navigationDelegate = self
webView.load(URLRequest(url: URL(string: url ?? "https://demo.dukanje.com/index.php?route=product/product_option&product_id=206&store_id=52&language_id=1")!))
activityIndicator?.startAnimating()
}
}
extension WebViewController: WKNavigationDelegate{
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
self.activityIndicator?.stopAnimating()
self.activityIndicator?.removeFromSuperview()
self.activityIndicator = nil
}
}
Я использовал расширения, чтобы помочь макет:
extension UIView{
func fillSuperView(){
translatesAutoresizingMaskIntoConstraints = false
guard let superview = superview else {return}
anchor(top: superview.topAnchor, left: superview.leadingAnchor, bottom: superview.bottomAnchor, right: superview.trailingAnchor)
}
func anchor(top: NSLayoutYAxisAnchor?, left: NSLayoutXAxisAnchor?, bottom: NSLayoutYAxisAnchor?, right: NSLayoutXAxisAnchor?, size: CGSize = .zero, padding: UIEdgeInsets = .zero){
translatesAutoresizingMaskIntoConstraints = false
if let top = top{
topAnchor.constraint(equalTo: top, constant: padding.top != 0 ? padding.top : 0).isActive = true
}
if let left = left{
leadingAnchor.constraint(equalTo: left, constant: padding.left != 0 ? padding.left : 0).isActive = true
}
if let bottom = bottom{
bottomAnchor.constraint(equalTo: bottom, constant: padding.bottom != 0 ? -padding.bottom : 0).isActive = true
}
if let right = right{
trailingAnchor.constraint(equalTo: right, constant: padding.right != 0 ? -padding.right : 0).isActive = true
}
if size.width != 0{
widthAnchor.constraint(equalToConstant: size.width).isActive = true
}
if size.height != 0{
heightAnchor.constraint(equalToConstant: size.height).isActive = true
}
}
}
