title: UIViewContentModeScale mode of the cell image change silently after the cell is touched(highlighted)
body: <p>EDIT:</p>
  
  <p>I get the issue fixed by create a customize cell.(However, still have another <a href="https://stackoverflow.com/questions/11788197/dequeuereusablecellwithidentifier-always-return-non-nil">questions</a>.) But why the default cell does not work is still a mystery...</p>
  
  <p>Cory 's answer did not fix the issue but <code>clipsToBounds</code> is really a point and I appreciated his continuous help. So I give him the bounty but not accept his answer as the answer. The answer still in the wind....</p>
  
  <p>================================</p>
  
  <p>I set the <code>UIViewContentModeScale</code> mode of the cell image to <code>AspectFill</code> (left image) and the image was correctly displayed(Fill the image view but keep the aspect). However, after touch and hold on the cell, image's will change: the imageView's frame and contentViewMode are changed. (see the first cell of the left image below )</p>
  
  <p>This is really wired and I can believe such as basic thing could goes wrong so there must be some stuff I was missing out. </p>
  
  <p>Environment: Xcode 4.3 iOS5.1 simulator &amp; device.

  <p>UPdate:</p>
  
  <p>I set the UIViewContentMode using the inspector of the storyboard.</p>
  
  <p>And by the way ,I used SDWebImage/UIImageView+WebCache.h.</p>
  
  <p>UPdate2:</p>
  
  <p>I set explicitly the content mode in the code but issue still there.
  [cell.imageView setContentMode:UIViewContentModeScaleAspectFill];</p>
  
  <p>update4:</p>
  
  <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
  {
      UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"AlbumCell"];
  
      if(cell == nil){
          cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"AlbumCell"];
  
      }
      //[cell.imageView setContentMode:UIViewContentModeScaleAspectFill];
      //[cell.imageView setClipsToBounds:YES];
      [self configureCell:cell atIndexPath:indexPath];
      return cell;
  }
  - (void)configureCell:(UITableViewCell *)cell atIndexPath:(NSIndexPath *)indexPath
  {
      Album *album = [self.fetchedResultsController objectAtIndexPath:indexPath];
      cell.textLabel.text = [album.title description];    
      cell.detailTextLabel.text = [self.userVisiableDateFormatter stringFromDate:album.releaseDate];
  
  
      //[cell.imageView setContentMode:UIViewContentModeScaleAspectFill];
      [cell.imageView setImageWithURL:[NSURL URLWithString:album.coverThumbnailUrl]
                  placeholderImage:[self placeHolderImage]];
  
  }
  </code></pre>
