parallaxable's Issues

Incorrect Position of Image when scrollToItem Is Called

@MaximKotliar I'm having an issue when I call collectionView.scrollToItem. The image that I am applying parallax too is not in the correct position after I call collectionView.scrollToItem.

This is the code that to scroll:

func refresh() {
    collectionView.reloadData()
    
    let indexPath = IndexPath(item: 0, section: 0)
    collectionView.scrollToItem(at: indexPath, at: [], animated: false)
}

This is the parallax code. I only add parallax to backgroundImageView:

private let parallaxOffsetMultiplier: CGFloat = 75

extension MyCollectionViewCell: Parallaxable {
	func updateHorizontalParallaxOffset(with offset: CGFloat) {
		var targetCenter = contentView.center
		targetCenter.x += offset * parallaxOffsetMultiplier
		targetCenter.y = backgroundImageView.center.y
		backgroundImageView.center = targetCenter
	}
}

Here is an image to illustrate the issue:

This issue is solved after I "manually" scroll by "swiping" on the screen.

Any suggestions?
