title: 3D Touch peek and pop trouble
body: <p>I'm trying to implement peek and pop feature in my application.but since I can't test it yet, I wanted to know if I was doing it correctly, I feel something is wrong? </p>
  
  <pre><code>- (UIViewController *)previewingContext:(id&lt;UIViewControllerPreviewing&gt;)previewingContext viewControllerForLocation:(CGPoint)location 
  {
      NSLog(@"TEST");
  
      NSIndexPath *indexPath = [self.myTableView indexPathForRowAtPoint:location];
  
      if (indexPath) {
          UITableViewCell *cell = [self.myTableView cellForRowAtIndexPath:indexPath];
          NSDictionary *dict = [self.array objectAtIndex:indexPath.row];
          cell.textLabel.text = [dict objectForKey:@"name"];
  
          DetailViewController *previewController = [[DetailViewController alloc] init];
          //     previewController.content = content;
  
          previewingContext.sourceRect = cell.frame;
  
          return previewController;
      }
  
  return nil;
  }
  </code></pre>
