For posterity, I fixed this by adding the following method:
- (UICollectionViewLayoutAttributes *)layoutAttributesForItemAtIndexPath:(NSIndexPath *)indexPath
{
//attributes are copied so that the collection view doesn't gripe about us modifying existing attribute objects
UICollectionViewLayoutAttributes *attributes = [[super layoutAttributesForItemAtIndexPath:indexPath] copy];
CGRect visibleRect = (CGRect){self.collectionView.contentOffset, self.collectionView.bounds.size};
CGFloat visibleCenterX = CGRectGetMidX(visibleRect);
CGFloat distanceFromCenter = visibleCenterX - attributes.center.x;
CGFloat absDistanceFromCenter = MIN(ABS(distanceFromCenter), kScalingOffset);
CGFloat scale = absDistanceFromCenter * (kMinimumScaleFactor - 1) / kScalingOffset + 1;
attributes.transform3D = CATransform3DScale(CATransform3DIdentity, scale, scale, 1);
return attributes;
}
It performs the same operations as - (NSArray *)layoutAttributesForElementsInRect:(CGRect)rect
but is able to apply attributes to cells before they enter the visible rect.

bump i cannot find an answer to this problem, plus once the cell becomes a certain size, the spacing between teh cells grow so only one is visible at a time on screen
from lglinearflow.
so anyone find an answer?
