Trigger Javascript Function on Web Page with Button on Toolbar

[iHAL]

Greetings,

I am in the process of creating a very simple native app for the iPad with Xcode 4. It consists of a UIWebView and a Toolbar with a few Buttons. When the app is launched, it loads a webpage that I have designed. The design scheme is that all the "work" is done by the web page.

Here is what I want to know how to do:
When a Toolbar Button is pressed - I want it to trigger a Javascript function on my webpage. This would be analogous to the HTML <...onclick:"GenericJavascriptFunctionName()".../>, only I want the same GenericJavacriptFunctionName() to be triggered when I press a Toolbar Button on my native app.

Thanks in advance

In case this can be useful to others, what I needed was "stringByEvaluatingJavaScriptFromString".

This leads me to another problem due to my being a n00b - how do I execute my stringByEvaluatingJavaScriptFromString when my toolbar button is pressed?

Actually that is a piece of cake! If another n00b happens to stumble upon this check out YouTube - iPhone SDK: Creating Buttons and Adding Actions & Alert View it shows you what you need to know!
