我正在尝试UICollectionViewCell使用material-components被调用来自定义MDCCardCollectionCell。但是，当我成功实现它时，这意味着当我单击每个单元格时，我可以看到动画等等。但是在实现该类之后的一个问题，当我单击每个单元格时，永远不会调用该MDCCardCollectionCell方法。didSelect
在它工作正常之前，在我实施MDCCardCollectionCell之后，问题就出现了。如何解决这个特定问题？
这是我到目前为止所做的
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: cellId, for: indexPath) as! ExploreCellData
cell.exploreData = exploreCategory?.data![indexPath.item]
cell.layer.shouldRasterize = true
cell.layer.rasterizationScale = UIScreen.main.scale
cell.isSelectable = true
cell.cornerRadius = 8
cell.setShadowElevation(ShadowElevation(rawValue: 6), for: .selected)
cell.setShadowColor(UIColor.black, for: .highlighted)
return cell
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
if let data = exploreCategory?.data![indexPath.item] {
if let titleImage = data.imageName {
print(titleImage)
// This will push to another view controller after selected
dashboardViewController?.showDetailEachItem(data: titleImage, imageContent: data.titleImage!, imageDesc: data.descImage!)
}
}
}
ExploreCellData是一个自定义单元格使用MDCCardCollectionCell
class ExploreCellData: MDCCardCollectionCell {
var exploreData: ExploreDataSection? {
didSet{
if let image = exploreData?.imageName {
viewsProperty.exploreImageView.image = UIImage(named: image)
viewsProperty.exploreNameLabel.text = exploreData?.titleImage
}
}
}
var viewsProperty = ExploreCategoryComponents()
let nameLabelView: UIView = {
let view = UIView()
view.translatesAutoresizingMaskIntoConstraints = false
view.layer.cornerRadius = 5
view.layer.masksToBounds = true
view.backgroundColor = .white
return view
}()
override init(frame: CGRect) {
super.init(frame: frame)
setupConstraint()
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
extension ExploreCellData {
func setupConstraint() {
addSubview(viewsProperty.cardView)
viewsProperty.cardView.frame = CGRect(x: 0, y: 0, width: frame.width, height: frame.height)
viewsProperty.cardView.addSubview(viewsProperty.exploreImageView)
viewsProperty.cardView.addSubview(nameLabelView)
viewsProperty.cardView.addSubview(viewsProperty.exploreNameLabel)
viewsProperty.exploreImageView.frame = CGRect(x: 5, y: 5, width: frame.width - 10, height: frame.height / 1.5)
// nameLabel.frame = CGRect(x: frame.width / 5, y: imageView.frame.maxY + 2, width: frame.width, height: frame.height / 4)
viewsProperty.exploreNameLabel.topAnchor.constraint(equalTo: viewsProperty.exploreImageView.bottomAnchor).isActive = true
viewsProperty.exploreNameLabel.widthAnchor.constraint(equalTo: self.widthAnchor).isActive = true
viewsProperty.exploreNameLabel.bottomAnchor.constraint(equalTo: viewsProperty.cardView.bottomAnchor).isActive = true
viewsProperty.exploreNameLabel.textAlignment = .center
// viewsProperty.exploreNameLabel.centerYAnchor.constraint(equalTo: nameLabelView.centerYAnchor).isActive = true
// viewsProperty.exploreNameLabel.centerXAnchor.constraint(equalTo: nameLabelView.centerXAnchor).isActive = true
}
}
