title: loadView on a storyboard ViewController during unitTesting with XCTest
body: <p>I have tried:</p>
  
  <pre><code>- (void)setUp {
      [super setUp];    
      UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
      self.asvc = [storyboard instantiateViewControllerWithIdentifier:@"addshopvc"];
      [self.asvc performSelectorOnMainThread:@selector(loadView) withObject:nil waitUntilDone:YES];
  }
  </code></pre>
  
  <p>but <code>-(void)viewDidLoad</code> doesn't get called in the View Controller. What am I doing wrong?</p>
