Setting cell in UICollectionView - objective-c

Question

I am attempting to set an imageView in a cell in a UICollectionview. No images ever appear. I am also tried to set a label but have had no luck
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
photoCollectionViewCell *photoCell = [collectionView dequeueReusableCellWithReuseIdentifier:reuseIdentifier forIndexPath:indexPath];
// Configure the cell
NSURL *url = [NSURL URLWithString:self.imageURLArray[indexPath.row]];
NSData *data = [[NSData alloc] initWithContentsOfURL:url];
UIImage *tmpImage = [[UIImage alloc] initWithData:data];
//photoCell.photoImageView.image = tmpImage;
photoCell.photoLabel.text = #"l";
return photoCell;
}
One thing I did notice is that "photoCell" always returns null.
I am registering my collectionview like this:
[self.collectionView registerClass:[photoCollectionViewCell class] forCellWithReuseIdentifier:reuseIdentifier];
My cell interface header file is:
#interface photoCollectionViewCell : UICollectionViewCell
#property (weak, nonatomic) IBOutlet UIImageView *photoImageView;
#property (weak, nonatomic) IBOutlet UILabel *photoLabel;
#end

My first guess would be to return an instance of photoCollectionViewCell instead of the default UICollectionViewCell:
- (photoCollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
}
Second guess:
Where do you set your "reuseIdentifier" variable and what value is assigned to it? You can set a reuseIdentifier as follows:
static NSString *CellIdentifier = #"MyCustomCell";
and then set it to your:
[self.collectionView registerClass:[photoCollectionViewCell class] CellIdentifier];
and:
photoCollectionViewCell *photoCell = [collectionView dequeueReusableCellWithReuseIdentifier:CellIdentifier forIndexPath:indexPath];
and register your ReuseIdentifier on your storyboard custom cell:
