title: Resize UIImageView in UITableViewCell
body: <p>I have a 16x16 pixel image that I want to display in an UIImageView. So far, no problem, however 16x16 is a bit small so I want to resize the image view to 32x32 and thus also scale the image up.
  But I can't get it to work, it always shows the image with 16x16, no matter what I try. I googled a lot, and found many snippets here on Stack Overflow, but its still doesn't work.
  Here is my code so far:</p>
  
  <pre><code>[[cell.imageView layer] setMagnificationFilter:kCAFilterNearest];
  [cell.imageView setAutoresizingMask:UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight];
  [cell.imageView setClipsToBounds:NO];
  [cell.imageView setFrame:CGRectMake(0, 0, 32, 32)];
  [cell.imageView setBounds:CGRectMake(0, 0, 32, 32)];
  [cell.imageView setImage:image];
  </code></pre>
  
  <p>I don't want to create a new 32x32 pixel image because I already have some memory problems on older devices and creating two images instead of having just one looks like a very bad approach to me (the images can be perfectly scaled and it doesn't matter if they lose quality).</p>
