Migrating from UIWebView to WKWebView

Question

in my app I\'m migrating from UIWebView to WKWebView , how can I rewrite these function for WKWebView?

    func webViewDidStartLoad(webView: UIWebView){}
            


        

Answer 1

Here is the Objective-C methods for the migration

1) shouldStartLoadWithRequest -> decidePolicyForNavigationAction

Remember to call the decisionHandler

- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler {
       if (navigationAction.navigationType == UIWebViewNavigationTypeLinkClicked) {

       }
       NSString *url = [navigationAction.request.URL query];

       decisionHandler(WKNavigationActionPolicyAllow);
}

2) webViewDidStartLoad -> didStartProvisionalNavigation

- (void)webView:(WKWebView *)webView didStartProvisionalNavigation:(WKNavigation *)navigation {
}

3) webViewDidFinishLoad -> didFinishNavigation

- (void)webView:(WKWebView *)webView didFinishNavigation:(WKNavigation *)navigation {
}

4) didFailLoadWithError -> didFailNavigation

- (void)webView:(WKWebView *)webView didFailNavigation:(WKNavigation *)navigation withError:(NSError *)error {
}
