title: Can't interact with UIView
body: <p>I am making a Facebook like Slide-To-Right Menu. My problem is I can't interact with the rear UIView. Here is my code:</p>
  
  <pre><code>@property (strong, nonatomic) UIViewController *leftSidebarViewController;
  
  
  self.leftSidebarViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"left"];
  [self.navigationController.view.superview insertSubview:self.leftSidebarViewController.view
                                             belowSubview:self.navigationController.view];
  [self.leftSidebarViewController.view setUserInteractionEnabled:YES];
  </code></pre>
  
  <p>Anyone know how to fix this?</p>
