How to catch UIWebView popup menu and customize items

Question

Hello everyone

I have a project need to catch the url link on UIWebView.

I hope it can customize the standard url popup menu 'open'-'Copy'-'Cancel'

change to 'Open'-Download'-'Cancel'.

I know the function

- (BOOL) webView:(UIWebView *)webView
        shouldStartLoadWithRequest:(NSURLRequest *)request
                    navigationType:(UIWebViewNavigationType)navigationType

but do not know how to make this works

Welcome any comment

Best Regards
