Hello, Team.
We used WKWebView for our project. We loaded the HTML file into the webview and added the following configuration.
weak var webView: WKWebView!
func configWebView() {
let webViewConfig = WKWebViewConfiguration()
let controller = WKUserContentController()
controller.add(self, name: "sometest")
webViewConfig.userContentController = controller
webViewConfig.processPool = WKProcessPool()
webViewConfig.setValue(true, forKey: "allowUniversalAccessFromFileURLs")
webViewConfig.mediaTypesRequiringUserActionForPlayback = []
let webpagePreferences = WKWebpagePreferences()
webpagePreferences.allowsContentJavaScript = true
webViewConfig.defaultWebpagePreferences = webpagePreferences
webViewConfig.websiteDataStore = WKWebsiteDataStore.default()
webView = WKWebView(frame: .zero, configuration: webViewConfig)
webView.navigationDelegate = self
webView.uiDelegate = self
webView.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(webView)
NSLayoutConstraint.activate([
webView.topAnchor.constraint(equalTo: view.topAnchor),
webView.bottomAnchor.constraint(equalTo: view.bottomAnchor),
webView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
webView.trailingAnchor.constraint(equalTo: view.trailingAnchor)
])
loadWebView()
}
func loadWebView() {
guard let documentsDirectoryURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first else {
return
}
let contentFolderURL = documentsDirectoryURL.appendingPathComponent("content")
let assetFolderURL = contentFolderURL.appendingPathComponent(interactiveGUID)
if FileManager.default.fileExists(atPath: assetFolderURL.path) {
let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first!
let documentsURL = URL(fileURLWithPath: documentsPath)
let fileToLoadPath = (documentsPath as NSString).appendingPathComponent("content/index_p.html")
let fileURL = URL(fileURLWithPath: fileToLoadPath)
autoreleasepool {
DispatchQueue.main.async { [weak self] in
guard let self = self else { return }
self.webView.loadFileURL(fileURL, allowingReadAccessTo: documentsURL)
}
}
}
We are experiencing webview crashes when loading an HTML file. What happened when I loaded the video file? It automatically looped. Webview frequently crashes when the HTM/JS file is loaded.
When a webview crashes, the delegate method usually calls webViewWebContentProcessDidTerminate. This method calls webview.reload().
Also we are clear and cache/ deallocate eveything when i initialized those configuration mentioned as the above.
Can you suggest a solution to this? Why is webview crashing?
Thank you.
