我的 UITapGestureRecognizer 影响 TableViewCell 中的所有元素

Question

我正在尝试做我的第一个应用程序，我需要添加 UITapGestureRecognizer 来缩放 TableViewCell 中的照片。

它可以工作，但不正确 — 我的手势不仅缩放了 ViewCell 中的照片，还缩放了 ViewCell 中的所有元素。我该如何解决这个问题？

我所有的 TableViewCell 代码：

import UIKit

class PhotosCollectionViewCell: UICollectionViewCell {
    
    static let identifier = "PhotosCollectionViewCell"
    
    @IBOutlet weak var mainPhoto: UIImageView!
    @IBOutlet weak var mainLabel: UILabel!
    
    var isInScale: Bool = false
        
    func configure(photo: PhotosInProfile) {
        mainPhoto.image = UIImage(named: photo.mainPhoto)
        mainLabel.text = "Date: \(photo.date)"
    }
    
    override func awakeFromNib() {
        super.awakeFromNib()
        let doubleTap = UITapGestureRecognizer(target: self, action: #selector(imageDoubleTapped))
        doubleTap.numberOfTapsRequired = 2
        mainPhoto.isUserInteractionEnabled = true
        mainPhoto.addGestureRecognizer(doubleTap)
    }
    
    @objc func imageDoubleTapped() {
        if isInScale {
            self.transform = .identity
        } else {
            self.transform = CGAffineTransform(scaleX: 1.5, y: 1.5)
        }
        isInScale.toggle()
    }
}

导入 UIKit

class PhotosCollectionViewCell: UICollectionViewCell {

static let identifier = "PhotosCollectionViewCell"

@IBOutlet weak var mainPhoto: UIImageView!
@IBOutlet weak var mainLabel: UILabel!

var isInScale: Bool = false
    
func configure(photo: PhotosInProfile) {
    mainPhoto.image = UIImage(named: photo.mainPhoto)
    mainLabel.text = "Date: \(photo.date)"
}

override func awakeFromNib() {
    super.awakeFromNib()
    let doubleTap = UITapGestureRecognizer(target: self, action: #selector(imageDoubleTapped))
    doubleTap.numberOfTapsRequired = 2
    mainPhoto.isUserInteractionEnabled = true
    mainPhoto.addGestureRecognizer(doubleTap)
}

@objc func imageDoubleTapped() {
    if isInScale {
        mainPhoto.transform = .identity
    } else {
        mainPhoto.transform = CGAffineTransform(scaleX: 1.5, y: 1.5)
    }
    isInScale.toggle()
}
