Question

I am working on a Cocoa WebView based browser application.

Basically, I would like to have it so when the user navigates to a url, for example:
http://a/b.php, by clicking on a link on the previous page of a website, my application intercepts the “on navigate” event and changes the URL to http://a/b.php?enableapi=1

Any ideas??

Thanks in advance.

You need to assign an object as the web view’s WebPolicyDelegate and implement the webView:decidePolicyForNavigationAction:request:frame:decisionListener: method.

In that method, you must call one of the WebPolicyDecisionListener protocol methods on the object that is passed as the decisionlistener parameter to the method. The three WebPolicyDecisionListener protocol methods are ignore, use or download.

You can then pass ignore to the listener and handle the link some other way for those links you’re interested in intercepting.
