Thank you.

Use "webview.request.URL.absoluteString" to get the request-string of the clicked link in the delegate-method "webViewDidFinishLoad:" or "webViewDidStartLoad:". then you can scan this url for some special substring.

For example you could make a link like ".../index.php?iPhone_action=abcdef". In the delegate-methods you can check if the link has the substring "?iPhone_action=" and if it does, then put the part of the link, whick follows "?iPhone_action=" in a NSString. (in our example it would be "abcdef"). Depending on the value of this NSString you could fire a action in your app.

There is an undocumented method to catch the event when you click on a link in UIWebView. You can do whatever you want to do in that method.Search on google/stackoverflow for it. Or see my answer in this stackoverflow post.
