title: Calling the delegate of a delegate
body: <p>I'm working on an iPhone project where I've inherited someone else's code. I have a situation where viewController A has a UIWebView and it is set as the delegate of that UIWebView.</p>
  
  <p>I also have a Class B which is set as the delegate of viewController A.</p>
  
  <p>In an instance of B I want to send some javascript using stringByEvaluatingJavaScriptFromString to the UIWebView in viewController A. </p>
  
  <p>What's the best way of doing it?</p>
