Adding text to a UIWebView text box

How can I physically put some text from a UITextField into a form in a UIWebView in my iOS app? Maybe a javascript string could be called to input the text?

Thanks!

Like Matt H suggested, you need to inject your javascript. So there are basically two parts to this problem. 1st you have your objective C.

    NSString *username = @"Fred";
    NSString *password = @"pAssw0rd"; 
    NSString *jsCallBack = [NSString stringWithFormat:@"updateWebForm('%@,%@');",username,password];    
    [self.webView stringByEvaluatingJavaScriptFromString:jsCallBack];

Then you will have your javascript function, i put mine in a .js file, that my webview page is linked to. 

updateWebForm(username,password)
{
 //here is where you will assign whatever html/javascript needed for your form.
}

You can inject Javascript into a UIWebView:

[webView stringByEvaluatingJavaScriptFromString:@"javascript goes here"];

Use that with $('#fieldid').val('fromuitextfield'); or with document.getElementById() or however you need to change the text field value property.
