How to open a Link to a PDF with wkwebview

Question

I created a simple iOS app, which opens a URL with WKWebView. On the website, there is a link to a PDF Document. When I open the site on my browser, I can click onto the Lin

Answer 1

Likely, you are using target="_blank" in your anchor tag. That opens up a new window to display the link. WKWebView is blocking your attempt to open a new window (at least by default).

The code below still does not create a new window, but instead opens the PDF, etc link in the current WKWebView. The other option seems to be to create a new WKWebView and return it, so the ios and open the link in that, but I don't want extra Views being created by every click on a website inside the WKWebView.

In your ViewController.viewDidLoad

webView.uiDelegate = self

Then add the extension for the delegate

extension ViewController: WKUIDelegate {

    /**
     * Force all popup windows to remain in the current WKWebView.  
     * By default, WKWebView is blocking new windows from being created
     * ex text.
     * This code catches those popup windows and displays them in the current WKWebView.
     */
    func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {

        // open in current view
        webView.load(navigationAction.request)

        // don't return a new view to build a popup into (the default behavior).
        return nil;
    }
}
