title: how to access from UICollectionViewCell the indexPath of the Cell in UICollectionView
body: <p>i want to animate the <code>UICollectionViewCell</code> when action is called.<br>
  i have done <code>UICollectionViewCell</code> in <code>Interface Builder</code>, the <code>UICollectionView</code> also.
  Now i want to get the correct <code>indexPath</code> at my <code>actionBtnAddToCard</code> method.</p>
  
  <p>thats the way i try it now (method in ProduktViewCell.m):  </p>
  
  <pre><code>- (IBAction)actionAddToCart:(id)sender {
      XLog(@"");
  
      // see this line
      NSIndexPath *indexPath = ??** how can i access the correct indexPath**??;
      SortimentViewController *svc = [[SortimentViewController alloc] initWithNibName:@"SortimentViewController_iPad" bundle:[NSBundle mainBundle]];
      [svc.collectionViewProdukte cellForItemAtIndexPath:indexPath];
  
      [svc collectionView:svc.collectionViewProdukte didSelectItemAtIndexPath:indexPath];
  } 
  </code></pre>
  
  <p>SortimentViewController is the viewController which inherits the UICollectionView.<br>
