Changes made in one tableviewcell effect other cells - ios

Question

My problem is, that I have a tableview with a number of cells. Inside of those cells there are images, that get a green border if they are being taped. If I have a lot of cells and I tap for example the first pic in the first cell, that's when the problem happens. When I start scrolling down the table a little faster, other cells of the same type also have the first picture with green border, even though they are in cell number 13 or something. I think that's because they are reusable cells, but how can I make sure, that only the one cell that is being taped, keeps the change? Hope you guys got what I meant, I know it's kinda confusing. Here is one of the two custom cells, with the code that turns the border green. The images of type bouncingRoundImages, are just UIImages, I created the custom subclass of UIImage to make them bounce.
class TwoPicsTableViewCell: UITableViewCell {
#IBOutlet var containerView: UIView!
#IBOutlet var firstImage: bouncingRoundImageView!
#IBOutlet var secondImage: bouncingRoundImageView!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
containerView.layer.cornerRadius = 10
containerView.clipsToBounds = true
setupFirstImage()
setupSecondImage()
}
func setupFirstImage() {
let tappedOne = UITapGestureRecognizer(target: self, action: #selector(checkPicTwo))
firstImage.addGestureRecognizer(tappedOne)
}
func setupSecondImage() {
let tappedTwo = UITapGestureRecognizer(target: self, action: #selector(checkPicOne))
secondImage.addGestureRecognizer(tappedTwo)
}
func checkPicTwo() {
firstImage.bouncing()
if secondImage.layer.borderWidth != 0 {
secondImage.layer.borderWidth = 0
}
}
func checkPicOne() {
secondImage.bouncing()
if firstImage.layer.borderWidth != 0 {
firstImage.layer.borderWidth = 0
}
}
}

It sounds like a reusable cell problem. Try setting the image to nil and borderWidth to 0 in prepareForReuse.
override func prepareForReuse()
{
super.prepareForReuse()
firstImage.image = nil
secondImage.image = nil
firstImage.layer.borderWidth = 0
secondImage.layer.borderWidth = 0
}
