WKWebView equivalent for UIWebView's scalesPageToFit

Question

I am updating my iOS app to replace UIWebView with WKWebView. However I don't understand how to achieve the same behavior with WKWebView. With UIWebView I used scalesPageToFit to ensure the web pag was displayed with the same size as the screen size (so as to appear full screen without scrolling).

I found that solution on the web however it does not work :

- (void)webView:(WKWebView *)webView didCommitNavigation:(WKNavigation *)navigation {     NSString *javascript = @"var meta = document.createElement('meta');meta.setAttribute('name', 'viewport');meta.setAttribute('content', 'width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no');document.getElementsByTagName('head')[0].appendChild(meta);";     [webView evaluateJavaScript:javascript completionHandler:nil]; } 

Answer 1

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 add additional configuration to your WKWebViewConfiguration.
