How to disable long touch in UIWebView?

The UIWebView is no longer supported. So, you should implement WKWebView and there is a property called allowsLinkPreview with that you can enable or disable the long touch previews.

 webView.allowsLinkPreview = false

In webViewDidFinishLoad delegate I run a javascript on the loaded html page that disable the long touch.

[webView stringByEvaluatingJavaScriptFromString:@"document.body.style.webkitTouchCallout='none'; document.body.style.KhtmlUserSelect='none'"];
