You should add some bindings between your webview and your Objective-C. You can do this using javascript.

You pretty much inject javascript into the webview so you will get a event when some HTML element is touched. Then your javascript will communicate to Objective C, to trigger some action.

This is technique is described pretty well here: http://blog.techno-barje.fr/post/2010/10/06/UIWebView-secrets-part3-How-to-properly-call-ObjectiveC-from-Javascript/
