The class UIWebView has a method called stringByEvaluatingJavaScriptFromString which you can use to load javascript code to a webview.

I use this method to execute javasctipt on my webview:

-(void) runjs:(NSString *)code
{
    @try 
    {
        if (webview)
            [webview stringByEvaluatingJavaScriptFromString: code];      
    }
    @catch (NSException *exception) 
    {
    }
}

Check the UIWebView method called:

stringByEvaluatingJavaScriptFromString:(NSString *)script;

NSString *result = [_webView stringByEvaluatingJavaScriptFromString:(@"alert('Hi')")];

You can use this method to call the javascript from html to iOS webview

[self.webView stringByEvaluatingJavaScriptFromString:@"my_html_function();"];

this may help you.
