Just a simple:

[webView stringByEvaluatingJavaScriptFromString:%your javascript string%];

Note 10 sec for execution and 10mb of ram per this call or it will be killed no matter if it finished execution or not.

Try to use [webView stringByEvaluatingJavaScriptFromString:@"your_javascript_here"];

we used this method to communicate between the native part of the app and the javascript inside a webview. I'd encapsulate your javascript in a function and call the function from the app via the suggested method.

I've executed java script for UIWebview in the following way

NSString *jsString = [[NSString alloc] initWithFormat:@"document.getElementsByTagName('body')[0].style.webkitTextSizeAdjust= '%f%%'",(fontSize * 10.0)];
[self stringByEvaluatingJavaScriptFromString:jsString];
  [jsString release];

Hope it may help you. Here self is an instance of UIWebView.
