NSInvalidUnarchiveOperationException when loading the nib / storyboard means there an object in the nib / storyboard that the runtime doesn’t understand. This is because the framework that defines that kind of object is missing. So, in this case, you need to link your app target against the WebKit framework so that the app understands what … Read more
Cookies used (created) by the WKWebView are actually correctly stored in the NSHTTPCookieStorage.sharedHTTPCookieStorage(). The problem is that the WKWebView does not write back the cookies immediately. I think it does this on its own schedule. For example when a WKWebView is closed or maybe periodically. So eventually they do end up in there, but when … Read more
To solve this you need a WKUIDelegate for your web view. It is the duty of the delegate to decide if an alert should be displayed, and in what way. You need to implement this for alert, confirm and text input (prompt). Here is sample code without any validation of the page url or security … Read more
If you are using swift, first import the WebKit module in any files you’re using web kit API: import WebKit Then you can use the web view: let webView = WKWebView()
I think I read every answer on this subject and all I had was part of the solution. Most of the time I spent trying to implement KVO method as described by @davew, which occasionally worked, but most of the time left a white space under the content of a WKWebView container. I also implemented … Read more
Correct as usual, King Friday. It turns out that the WKUserContentController retains its message handler. This makes a certain amount of sense, since it could hardly send a message to its message handler if its message handler had ceased to exist. It’s parallel to the way a CAAnimation retains its delegate, for example. However, it … Read more
You are correct – it doesn’t seem to work. If you look in the headers, you’ll see: – (instancetype)initWithCoder:(NSCoder *)coder NS_UNAVAILABLE; which implies that you can’t instantiate one from a nib. You’ll have to do it by hand in viewDidLoad or loadView.
Check if you use in your code the UIWebView class; if yes replace your implementation with WKWebView, else need check your Pods. Go with terminal into your project folder and execute the command: grep -r “UIWebView” . All matched pod must be updated. Now I’m stuck because I found UIWebView into Google AdMob (version 7.49.0) … Read more
Finally, solved the problem above. I was receiving errors Could not signal service com.apple.WebKit.WebContent: 113: Could not find specified service Since I have not added WKWebView object on the view as a subview and tried to call -loadHTMLString:baseURL: on the top of it. And only after it was successfully loaded I was adding it to … Read more
you can also try the WKUserScript. here’s my working config: NSString *jScript = @”var meta = document.createElement(‘meta’); meta.setAttribute(‘name’, ‘viewport’); meta.setAttribute(‘content’, ‘width=device-width’); document.getElementsByTagName(‘head’)[0].appendChild(meta);”; WKUserScript *wkUScript = [[WKUserScript alloc] initWithSource:jScript injectionTime:WKUserScriptInjectionTimeAtDocumentEnd forMainFrameOnly:YES]; WKUserContentController *wkUController = [[WKUserContentController alloc] init]; [wkUController addUserScript:wkUScript]; WKWebViewConfiguration *wkWebConfig = [[WKWebViewConfiguration alloc] init]; wkWebConfig.userContentController = wkUController; wkWebV = [[WKWebView alloc] initWithFrame:self.view.frame configuration:wkWebConfig]; you can … Read more
