I have assigned delegate to wkwebview uiDelegate and implemented it's method create web view with configuration, but it is not being called. I have even placed breakpoint but it is not hitting.
class ViewController: UIViewController, WKUIDelegate, WKNavigationDelegate {
#IBOutlet weak var webView: WKWebView!
override func viewDidLoad() {
super.viewDidLoad()
webView.navigationDelegate = self
webView.uiDelegate = self
let requestURL = URL(string: "https://www.google.com")!
let request = URLRequest(url: requestURL)
webView.load(request as URLRequest)
}
func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {
let config = WKWebViewConfiguration()
return WKWebView(frame: webView.frame, configuration: config)
}
func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {
}
}
It seems like it doesnt call the delegate on the initial init of the webview ... I recommend you to just create the webview from code
let configuration = WKWebViewConfiguration()
configuration.allowsInlineMediaPlayback = true
configuration.allowsAirPlayForMediaPlayback = true
configuration.mediaTypesRequiringUserActionForPlayback = []
webView = WKWebView(frame: containerView.frame, configuration: configuration)
webView.translatesAutoresizingMaskIntoConstraints = false
containerView.addSubview(webView)
NSLayoutConstraint.activate([
webView.leadingAnchor.constraint(equalTo: containerView.leadingAnchor),
webView.trailingAnchor.constraint(equalTo: containerView.trailingAnchor),
webView.topAnchor.constraint(equalTo: containerView.topAnchor),
webView.bottomAnchor.constraint(equalTo: containerView.bottomAnchor)
])
the containerview is just a basic UIView set in my xib so just set this uiview in your xib instead of a wkwebview and you should be good to go

I'm new to swift & am attempting to open a login page, login, use the WKNavigationDelegate to get the redirect uri and save the response. I was able to open the url using UIApplication.shared.open but attempting to hit the url using WKWebview, I am getting a loaded response but no view appears.
Am I not declarling the view correctly or is WKWebView not supposed to be used in that manner? This is the code i'm running, its building succesfully and responding that its 'loaded'. Any help would be be appreciated thanks.
import UIKit
import WebKit
class ViewController: UIViewController, WKUIDelegate, WKNavigationDelegate {
// The webview
var webViewObj: WKWebView!
var webNav: WKNavigation!
// this calls the dbhelper to create a db and a table
let db = DBHelper()
var list = [DBGrade]()
override func loadView() {
super.loadView()
let webConfiguration = WKWebViewConfiguration()
webViewObj = WKWebView(frame: .zero, configuration: webConfiguration)
}
override func viewDidLoad() {
super.viewDidLoad()
let url = URL(string: "https://www.hackingwithswift.com")
let request = URLRequest(url: url!)
webViewObj.navigationDelegate = self
self.webViewObj.uiDelegate = self
webViewObj.load(request)
}
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
print("loaded")
}
func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {
if navigationAction.targetFrame == nil {
webView.load(navigationAction.request)
}
return nil
}
func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: #escaping (WKNavigationActionPolicy) -> Void) {
let hostStr = String(describing: navigationAction.request.url)
let host = hostStr
if host.range(of: "hackingwithswift.com") != nil {
decisionHandler(.allow)
print("did it")
return
}
else{
decisionHandler(.cancel)
}
}
}
So moving my delcaration of 'self.webViewObj.uiDelegate = self' & adding 'view = webViewObj' to the loadView() function worked & I'm able to see the webpage appear.
I'm developing an app that is basically a Web View displaying a website designed to mimic an app. The majority of URLs will be internal however there will be a few which will redirect to other sites. All these links will have target="_blank".
I've spent days browsing this site and others to find a solution that will open _blank URLs in safari however everything I've tried has failed.
Any help with this would be much appreciated. I've added below the code from my View Controller
import UIKit
import WebKit
class ViewController: UIViewController, WKUIDelegate, WKNavigationDelegate {
#IBOutlet weak var webView:WKWebView!
override func viewDidLoad() {
super.viewDidLoad()
webView.uiDelegate = self
let myURL = URL(string:"https://example.com")
let myRequest = URLRequest(url: myURL!)
webView?.load(myRequest)
}}
func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {
if let frame = navigationAction.targetFrame,
frame.isMainFrame {
return nil
}
webView.load(navigationAction.request)
return nil
}
replace your createWebViewWith with this one
extension ViewController: WKUIDelegate {
//This opens maps or any other url given in new tab
func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {
if navigationAction.targetFrame == nil {
webView.load(navigationAction.request)
}
return nil
}
}
First of all I'm new in swift. I have a WebView app for iOS device using swift language , can add button back to previous page ?
import WebKit
class ViewController: UIViewController, WKNavigationDelegate {
var webView: WKWebView!
override func loadView() {
webView = WKWebView()
webView.navigationDelegate = self
view = webView
}
override func viewDidLoad() {
super.viewDidLoad()
let url = URL(string: "https://google.com/")!
webView.load(URLRequest(url: url))
webView.allowsBackForwardNavigationGestures = true
let statusBarFrame = UIApplication.shared.statusBarFrame
let statusBarView = UIView(frame: statusBarFrame)
self.view.addSubview(statusBarView)
statusBarView.backgroundColor = .systemBackground
}
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
title = webView.title
}
}
My code successfully loads the web page that I want it to; however, I'm having issues adding my activity indicator for while it is loading.
I am relatively new to swift, so I was reading other stackexchange examples. I created a UIActivityIndicator, set it in the override func, but it doesn't show up.
The webpage loads fine. Here is the runnable code.
import UIKit
import WebKit
class FeedbackWebViewController: UIViewController, WKNavigationDelegate {
let indicator = UIActivityIndicatorView(style: .gray)
var webView: WKWebView!
override func loadView() {
webView = WKWebView()
webView.navigationDelegate = self
indicator.center = webView.center
indicator.hidesWhenStopped = true
webView.addSubview(indicator)
view = webView
}
override func viewDidLoad() {
super.viewDidLoad()
let url = URL(string: "https://www.apple.com")!
webView.load(URLRequest(url: url))
webView.allowsBackForwardNavigationGestures = true
self.indicator.startAnimating()
}
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
indicator.stopAnimating()
}
func webView(_ webView: WKWebView, didFail navigation: WKNavigation!, withError error: Error) {
indicator.stopAnimating()
}
}
DONT override loadView. bad things may happen.
move code in didLoad. it should work.
try to put the related 3 lines to viewDidAppear rather than viewDidLoad. It works for me.
I have a wkwebview app, I need help with my code, I can't seems to open external links from my website inside my app.
import UIKit
import WebKit
import UserNotifications
class ViewController: UIViewController, WKUIDelegate, WKNavigationDelegate {
var webView: WKWebView!
var activityIndicator: UIActivityIndicatorView!
var bgImage: UIImageView!
var urlString = ""
override func loadView() {
super.loadView()
let webConfiguration = WKWebViewConfiguration()
webView = WKWebView(frame: .zero, configuration: webConfiguration)
webView.uiDelegate = self
webView.navigationDelegate = self
view = webView
}
func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {
if navigationAction.targetFrame == nil {
let vc = ViewController()
vc.urlString = navigationAction.request.url?.absoluteString ?? "https://mywebsite"
vc.view.frame = UIScreen.main.bounds
vc.webView = WKWebView(frame: UIScreen.main.bounds, configuration: configuration)
navigationController?.pushViewController(vc, animated: false)
return vc.webView
}
return nil
}
override var prefersStatusBarHidden: Bool{
return true
}
override func viewDidLoad() {
super.viewDidLoad()
let image : UIImage = UIImage(named:"bgx1")!
bgImage = UIImageView(image: image)
bgImage.frame = CGRect(x: 0, y: 0, width: 1000, height: 2000)
view.addSubview(bgImage)
let myURL = URL(string: "https://mywebsite/")
let myRequest = URLRequest(url: myURL!)
webView.load(myRequest)
webView.allowsBackForwardNavigationGestures = true
activityIndicator = UIActivityIndicatorView()
activityIndicator.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
self.activityIndicator.center = CGPoint(x:self.view.bounds.size.width/2.0,y: self.view.bounds.size.height/2.0);
activityIndicator.autoresizingMask = (UIView.AutoresizingMask(rawValue: UIView.AutoresizingMask.RawValue(UInt8(UIView.AutoresizingMask.flexibleRightMargin.rawValue) | UInt8(UIView.AutoresizingMask.flexibleLeftMargin.rawValue) | UInt8(UIView.AutoresizingMask.flexibleBottomMargin.rawValue) | UInt8(UIView.AutoresizingMask.flexibleTopMargin.rawValue))))
activityIndicator.hidesWhenStopped = true
activityIndicator.style = UIActivityIndicatorView.Style.whiteLarge
activityIndicator.color = UIColor.darkGray
self.view.addSubview(activityIndicator)
}
func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {
activityIndicator.startAnimating()
bgImage.startAnimating()
}
func webView(_ webView: WKWebView, didFailProvisionalNavigation navigation: WKNavigation!, withError error: Error) {
print("It is an error")
activityIndicator.stopAnimating()
bgImage.stopAnimating()
let alert = UIAlertController(title: "Network Error", message: "You have no internet connection", preferredStyle: .alert)
let restartAction = UIAlertAction(title: "Reload page", style: .default, handler: { (UIAlertAction) in
self.viewDidLoad()
})
alert.addAction(restartAction)
present(alert, animated: true, completion: nil)
}
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
activityIndicator.stopAnimating()
bgImage.stopAnimating()
bgImage.isHidden = true
}
}
What am I doing wrong? Please help.
You have to implement the webView(_:decidePolicyFor:decisionHandler:) function of WKNavigationDelegate protocol in order to allow following the links in your web view.
Here is the documentation
please use this webview as I shown in image
code:-
#IBOutlet weak var webView: UIWebView!
override func viewDidLoad() {
super.viewDidLoad()
webView.delegate = self;
webView.loadRequest(URLRequest.init(url: URL(string: "https://mywebsite")!));
}
func webViewDidStartLoad(_ webView: UIWebView) {
SVProgressHUD.setDefaultMaskType(SVProgressHUDMaskType.custom)
SVProgressHUD.show();
}
func webViewDidFinishLoad(_ webView: UIWebView) {
SVProgressHUD.dismiss();
}
