Animate cell when pressed using Swift 3

Question

My problem is really simple. I would like to animate a cell within a collectionView. Indeed, I would like to show a grey background behind the cell and scale down the image

Answer 1

If you need implement this functionality only for the specific cell, just add this code to you cell implementation:

override var isHighlighted: Bool {
  didSet {
    UIView.animate(withDuration: 0.5) {
      let scale: CGFloat = 0.9
      self.transform = self.isHighlighted ? CGAffineTransform(scaleX: scale, y: scale) : .identity
    }
  }
}

It is the same answer that suggested [pgdev][1] but for isHighlighted
