Is it possible to implement a custom behavior for 3D Touch on links with WKWebView?

Question

I'm trying to add my own implementation of 3D touch on links with WKWebView so I set the allowsLinkPreview property of my WKWebView to false.

But then, impossible to check whether the 3D touch was on a link and impossible to know what link neither.

So I'm wondering if there's a way to set the allowsLinkPreview property to true and then to catch the peek event that's triggered when 3D Touching a link?

Answer 1

It is possible. You should set the allowsLinkPreview value to true and then implement the following methods. Both methods need implemented or else it won't work.

optional func webView(_ webView: WKWebView,  previewingViewControllerForElement elementInfo: WKPreviewElementInfo,  defaultActions previewActions: [WKPreviewActionItem]) -> UIViewController?
optional func webView(_ webView: WKWebView,  commitPreviewingViewController previewingViewController: UIViewController)

In my case, I didn't want to create a previewViewController so I just returned an SFSafariViewController and passed in my url. That seemed to work perfectly. As for the commitPreviewingViewController method, that is where I put my code to open up a new tab in my browser.
