I am using UICollectionViewLayoutAttributes to apply a transform to one of my cells.
The transform I would like to apply is
CATransform3D transform = CATransform3DMakeTranslation(dx, dy, 0);
attributes.transform3D = CATransform3DScale(transform, rx, ry, 1);
with numbers dx, dy, rx and ry.
The problem is that this expression is ok for an anchorPoint which is not the center of my cell. It seems that the default anchorPoint is the middle. So, I would like to specify to my attributes what is the anchorPoint.
Is there a way to do that?
PS: I don't have much control for transforming my cell other than the attributes. Actually, this transform is applied in the method - (UICollectionViewLayoutAttributes*)initialLayoutAttributesForAppearingItemAtIndexPath:(NSIndexPath *)itemIndexPath
