If you want a fetchResult with all images, you can solve it like this:

// Property in your UICollectionViewController.h file
@property (strong, nonatomic) PHFetchResult *allPhotosFetchResult;

// In your awakeFromNib or where you refresh your Data
PHFetchOptions *allPhotosOptions = [PHFetchOptions new];
allPhotosOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:NO]];
self.allPhotosFetchResult = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:allPhotosOptions];

In your collectionView:cellForItemAtIndexPath: method you can access the asset with

self.allPhotosFetchResult[indexPath.row];

To get the number of rows in collectionView:numberOfItemsInSection:

self.allPhotosFetchResult.count

What do you mean with "one by one"? Each cell displays one asset/image. Everything else is based on your cellSize and CollectionViewLayout. You should really clarify your question above. – Thyraz Mar 25 '15 at 08:19
