title: Keep value of UICollectionView Cell
body: <p>There is a label in UICollectionViewCell.
  I made 6 cells in UICollectionView and assigned a number (1-6) to a label in each cell.
  I call [UICollectionView reloadData] and expect same number in label.
  But, a label value is changed when cellForItemAtIndexPathas is called, like "1 3 1 3 1 3".
  It seems UICollectionViewCell is relocated in cellForItemAtIndexPathas. </p>
  
  <p>Is there any way to keep it?</p>
  
  <pre><code>-(UICollectionViewCell*)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
  {
      InfoCollectionViewCell *infoCell = [collectionView dequeueReusableCellWithReuseIdentifier:@"InfoCell" forIndexPath:indexPath];
  
      [infoCell.cellText setText:[infoCell.cellText.text stringByAppendingString:[NSString stringWithFormat:@"%d\n",indexPath.row]]];
  
      return infoCell;
  }
  </code></pre>
