uiwebview

I want to generate some HTML content and put this into a UIWebView. The HTML contains some buttons. Is it possible to define actions for these buttons? I want to call a method (e.g. firstButtonPressed) in my objective-c code when someone presses this button in the UIWebView. Thanks you for helping me. Just to follow up on this, it is possible, and not to difficult to connect HTML/javascript events to objective-c methods.
