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'"];

- (void)webViewDidFinishLoad:(UIWebView*)theWebView { [theWebView stringByEvaluatingJavaScriptFromString:@"document.body.style.webkitTouchCallout='none'; document.body.style.KhtmlUserSelect='none'"]; } But still not working for me – Achal Gandhi Feb 08 '17 at 12:44

@Denny this answer is from 2015 I might that webkit have changed a bit since then. The idea should be the same, inject javascript in to the web view that will disable the long touch. – Alex Terente Oct 01 '18 at 13:13

You can also add : `[webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.style.webkitUserSelect='none';"];` for Objective-C or `webView.stringByEvaluatingJavaScript(from: "document.documentElement.style.webkitUserSelect='none';")` for Swift – Bejil Jun 28 '19 at 15:25

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

You could try to override the following methods from the view controller :
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event;
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event;
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event;
this way you can replace the usual touches management with your own implementation.

Open your view in Interface Builder, click on the web view and then un-check the "User Interaction Enabled" checkbox in the attributes inspector.
If you want to do it in code, set the web view's userInteractionEnabled property to NO.
