please ensure subView is UIWebView object, and also you steel need return YES or NO in shouldStartLoadWithRequest method. And one more little solution - open safari debugger with simulator or device and check this function manually in console

shouldStartLoadWithRequest calls before any content loaded, so you need to add some check that is not first request, or move all code to for example webViewDidFinishLoad
