title: Objective C: Can I set a subview to be firstResponder?
body: <p>I have a situation whereby I am adding a view from another viewcontroller to an existing viewcontroller. For example:</p>
  
  <pre><code>//set up loading page
  self.myLoadingPage = [[LoadingPageViewController alloc]init ];
  self.myLoadingPage.view.frame = self.view.bounds;
  self.myLoadingPage.view.hidden = YES;
  
  [self.view addSubview:self.myLoadingPage.view];
  </code></pre>
  
  <p>Is it possible to set 'self.myLoadingPage' to be the first responder? This is the case whereby the loadingpage view size does not cover the entire size of the existing view and users can still interact with the superview (which is not the desired behaviour). I want to just enable the subview in this case. </p>
