问题
I am rendering a local index.html file inside my Xcode project, using WKWebView
. The thing is, the html and css code inside the file are successfully displayed inside the webView, but the javaScript
however, is not rendered at all.
I have searched similar questions on this issue on stackoverflow and what I came up with is that Apple does not execute js in a local html file, and in order to execute js I am required to use a local webserver using GCDWebServer
.
To be honest I am new to the hole webServer concept and I'm finding it hard to figure how to run the html in a local webServer and how to this with GCDWebServer
.
What's the simple way to run my index.html file on a local server inside WKWebView and how to do so
here is my code:
override func viewDidLoad() {
super.viewDidLoad()
let resourceUrl = Bundle.main.url(forResource: "index", withExtension: "html")
let urlRequest = URLRequest.init(url: resourceUrl!)
webView.load(urlRequest)
webView.allowsBackForwardNavigationGestures = true
}

This is how I managed to create a GCDWebServer
local server with js files rendering successfully with html
script tags and with no need for JS injections such as WkUserscript
or evaluateJavaScript
my code:
import UIKit
import WebKit
import GCDWebServer
class ViewController: UIViewController, WKUIDelegate, WKNavigationDelegate{
var wkWebView: WKWebView!
var webServer = GCDWebServer()
var contentController = WKUserContentController()
func initWebServer() {
let folderPath = Bundle.main.path(forResource: "www", ofType: nil)
webServer.addGETHandler(forBasePath: "/", directoryPath: folderPath!, indexFilename: "index.html", cacheAge: 0, allowRangeRequests: true)
webServer.start(withPort: 8080, bonjourName: "GCD Web Server")
}
public override func viewDidLoad() {
super.viewDidLoad()
initWebServer()
let config = WKWebViewConfiguration()
config.userContentController = contentController
wkWebView = WKWebView(frame: view.bounds, configuration: config)
wkWebView.scrollView.bounces = false
wkWebView.uiDelegate = self
wkWebView.navigationDelegate = self
view.addSubview(wkWebView!)
wkWebView.load(URLRequest(url: webServer.serverURL!))
}
}
