(I filed a Radar for this shortly after asking the question here.) A new method was just added a few days ago (thanks jcesarmobile for pointing it out): Add -[WKWebView evaluateJavaScript:completionHandler:] http://trac.webkit.org/changeset/169765 The method is available in iOS 8 beta 3 and up. Here’s the new method signature: /* @abstract Evaluates the given JavaScript string. … 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
You can also request for access programmatically, which I prefer because in most cases you need to know if you took the access or not. Swift 4 update: //Camera AVCaptureDevice.requestAccess(for: AVMediaType.video) { response in if response { //access granted } else { } } //Photos let photos = PHPhotoLibrary.authorizationStatus() if photos == .notDetermined { PHPhotoLibrary.requestAuthorization({status … Read more
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
You can implement WKNavigationDelegate, add the decidePolicyForNavigationAction method and check there the navigationType and requested url. I have used google.com below but you can just change it to your domain: Xcode 8.3 • Swift 3.1 or later import UIKit import WebKit class ViewController: UIViewController, WKNavigationDelegate { let webView = WKWebView() override func viewDidLoad() { super.viewDidLoad() … 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
My solution is to cancel the navigation and load the request with loadRequest: again. This will be come the similar behavior like UIWebView which always open new window in the current frame. Implement the WKUIDelegate delegate and set it to _webview.uiDelegate. Then implement: – (WKWebView *)webView:(WKWebView *)webView createWebViewWithConfiguration:(WKWebViewConfiguration *)configuration forNavigationAction:(WKNavigationAction *)navigationAction windowFeatures:(WKWindowFeatures *)windowFeatures { if … Read more
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
This is kind of a hack, but the only way I found to accomplish this. First set yourself as WKWebView navigation delegate: self.webView?.navigationDelegate = self Now listen to all navigation changes, and save the requested url: func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) { if let urlStr = navigationAction.request.url?.absoluteString { … Read more
They finally solved the bug! Now we can use -[WKWebView loadFileURL:allowingReadAccessToURL:]. Apparently the fix was worth some seconds in WWDC 2015 video 504 Introducing Safari View Controller For iOS8 ~ iOS10 (Swift 3) As Dan Fabulish’s answer states this is a bug of WKWebView which apparently is not being solved any time soon and as … Read more
