title: Can't change button background image
body: <p>I am using Xcode 6, and I am very new to iOS development.</p>
  
  <p>I am trying to set a background image on an button. I have the button inside of a grid cell. Here is the code I have tried:</p>
  
  <pre><code>- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
  
      CollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:reuseIdentifier forIndexPath:indexPath];
  
      // Configure the cell
  
      if(indexPath.row + 1 == 1){
          [cell.gridButton setBackgroundImage:[UIImage imageNamed:@"image.png"] forState:UIControlStateNormal];        
      }
  
      return cell;
  }
  </code></pre>
  
  <p>I have tried some other methods but I am not having any luck. Could anyone please help me and possibly explain.</p>
