title: UICollectionView Crash?
body: <p>I'm trying to use a <code>UICollectionView</code> in collaboration with a <code>UICollectionViewCell</code> to display thumbnails of images. The <code>UICollectionViewCell</code>'s used in my app are custom (simplistic) subclasses:  </p>
  
  <pre><code>#import "MemeCell.h"
  
  @implementation MemeCell
  
  - (id)initWithFrame:(CGRect)frame
  {
      self = [super initWithFrame:frame];
      if (self) {
  
  }
  return self;
  }
  
  -(void)setThumb:(UIImage *)image {
      if (_thumb != image) {
          _thumb = image;
      }
  
      _imageThumb.image = _thumb;
  }
  
  @end
  </code></pre>
  
  <p>And in the <code>File's Owner</code> of my <code>UICollectionView</code>, I use:</p>
  
  <pre><code>- (UICollectionViewCell *)collectionView:(UICollectionView *)cv cellForItemAtIndexPath:(NSIndexPath *)indexPath {
  
      static BOOL nibLoaded = NO;
  
  if (!nibLoaded) {
      UINib *cellNib = [UINib nibWithNibName:@"MemeCell" bundle:nil];
      [_collectionView registerNib:cellNib forCellWithReuseIdentifier:@"MemeCell"];
      nibLoaded = YES;
  }
  
  MemeCell *cell = [cv dequeueReusableCellWithReuseIdentifier:@"MemeCell" forIndexPath:indexPath];
  
  NSString *path = [_imageThumbs objectAtIndex:indexPath.section];
  UIImage *thumb = [UIImage imageNamed:path];
  [cell setThumb:thumb];
  
  return cell;
  }
  </code></pre>
  
  <p>to return a cell. The view works fine when it is first presented, but after dismissing itself from it's delegate calling <code>[self dismissViewControllerAnimated:YES completion:nil]</code>, it cannot be presented again without crashing with a</p>

  </code></pre>
  
  <p>Can anyone provide insight?</p>
