UIWebView won't hide keyboard
===

I need to hide the keyboard as soon as a page starts loading. I've tried all commonly suggested approaches discussed e.g. [here](http://stackoverflow.com/questions/2563201/how-to-dismiss-keyboard-on-a-uiwebview)

Following approaches have no effect on the keyboard

* `[webView endEditing:YES];`
* `[webView stringByEvaluatingJavaScriptFromString:@"document.activeElement.blur();"];`
* `[webView stringByEvaluatingJavaScriptFromString:@"window.blur();"];`

I invoke them in `webView:shouldStartLoadWithRequest:navigationType:`

What am I doing wrong? Any suggestions?
