CABasicAnimation stops when UICollectionView is reloaded - uicollectionview

Question

I need help with an issue in Collection Views. In my collectionView I am using UILongPressGestureRecognizer to start CABasicAnimation in the items (images), but when I remove an item and reload the collectionView the CABasicAnimation is interrupeted.
How can I prevent the animation stop?
I need the animation continues until the user decide to stop.
Here is some information about my collectionView:
class SentMemesCollectionVC: UICollectionViewController {
//MARK: - PROPERTIES
var memes: [Meme]! {
return Meme.accessMemes().memes
}
//MARK: - LIFE CYCLE
override func viewDidLoad() {
super.viewDidLoad()
let longPressGesture = UILongPressGestureRecognizer(target: self, action: #selector(longTap(_:)))
self.collectionView.addGestureRecognizer(longPressGesture)
}
#objc func longTap(_ gesture: UILongPressGestureRecognizer) {
switch gesture.state {
case .began:
print("LongPress begin")
guard let selectedIndexPath = collectionView.indexPathForItem(at: gesture.location(in: collectionView)) else {return}
collectionView.beginInteractiveMovementForItem(at: selectedIndexPath)
setEditing(true, animated: true)
default:
collectionView.cancelInteractiveMovement()
}
}
// MARK: - COLLECTIONVIEW DATA SOURCE
//Defini o número de itens em cada seção
override func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return memes.count
}
override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "gridCell", for: indexPath) as! GridMemeCell
let meme = memes[indexPath.row]
cell.prepareGridCell(with: meme)
cell.delegate = self
return cell
}
// MARK: - COLLECTIONVIEW DELEGATE
/*
override func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
let memeDetail = storyboard?.instantiateViewController(withIdentifier: "DetailVC") as! MemeDetailVC
let meme = memes[indexPath.row]
memeDetail.memeSelected = meme
Feedback.share.hapticFeedback()
navigationController?.pushViewController(memeDetail, animated: true)
}
*/
// MARK: - DELETE ITEMS IN COLLECTVIEW
override func setEditing(_ editing: Bool, animated: Bool) {
super.setEditing(editing, animated: animated)
Feedback.share.hapticFeedback()
if let indexPaths = collectionView?.indexPathsForVisibleItems {
for indexPath in indexPaths {
if let cell = collectionView?.cellForItem(at: indexPath) as? GridMemeCell {
if editing {
cell.isEditing = editing
cell.startAnimate()
doneBarButtonItem()
} else {
cell.isEditing = editing
cell.stopAnimate()
addBarButtonItem()
}
}
}
}
}
}
Here is my CollectionViewCell
class GridMemeCell: UICollectionViewCell {
//MARK: - OUTLETS
#IBOutlet weak var ivImage: UIImageView!
#IBOutlet weak var deleteMeme: UIVisualEffectView!
//MARK: - PROPERTIES
weak var delegate: GridMemeCellDelegate?
var isAnimate: Bool! = true
//MARK: - METHODS AND COMPUTED PROPERTIES
func prepareGridCell(with meme: Meme) {
ivImage.image = meme.memeImage
deleteMeme.layer.cornerRadius = deleteMeme.bounds.width / 2.0
deleteMeme.layer.masksToBounds = true
deleteMeme.isHidden = !isEditing
deleteMeme.contentView.backgroundColor = Theme.current.subViewColor
}
func startAnimate() {
let shakeAnimation = CABasicAnimation(keyPath: "transform.rotation")
shakeAnimation.duration = 0.05
shakeAnimation.repeatCount = 4
shakeAnimation.autoreverses = true
shakeAnimation.duration = 0.2
shakeAnimation.repeatCount = 99999
let startAngle: Float = (-2) * 3.14159 / 180
let stopAngle = -startAngle
shakeAnimation.fromValue = NSNumber(value: startAngle)
shakeAnimation.toValue = NSNumber(value: 3 * stopAngle)
shakeAnimation.autoreverses = true
shakeAnimation.timeOffset = 290 * drand48()
let layer: CALayer = self.layer
layer.add(shakeAnimation, forKey: "animate")
self.deleteMeme.isHidden = false
isAnimate = true
}
func stopAnimate() {
let layer: CALayer = self.layer
layer.removeAnimation(forKey: "animate")
self.deleteMeme.isHidden = true
isAnimate = false
}
var isEditing: Bool = false {
didSet {
deleteMeme.isHidden = !isEditing
}
}
#IBAction func btDeleteMeme(_ sender: Any) {
Feedback.share.hapticFeedback()
delegate?.deleteCell(cell: self)
}
}
And here is my Protocol Delegate Cell:
protocol GridMemeCellDelegate: class {
func deleteCell(cell: GridMemeCell)
}
And here is my extension CollectionView - Delegate.
extension SentMemesCollectionVC: GridMemeCellDelegate {
func deleteCell(cell: GridMemeCell) {
if let indexPath = collectionView.indexPath(for: cell) {
//Apaga o Meme do Array
Meme.accessMemes().memes.remove(at: indexPath.item)
collectionView.reloadData()
}
}
}
