Yes you can set the text for a textfield in the UIWebView using javascript

As an example if you have a textfield in this form

<input id="textFieldID" type="text" value="TextValue"/>

Setting value:

[theWebView stringByEvaluatingJavaScriptFromString:@"document.getElementById('textFieldID').value = 'Hello World'"]

Getting value:

NSString* value = [theWebView stringByEvaluatingJavaScriptFromString:@"document.getElementById('textFieldID').value"];
