CollectionView确实选择了未调用时间

Question

我在轻按卡片以进行翻转时遇到问题。在我测试打印功能时，没有调用did select函数，这表明它根本没有轻按。可以帮忙吗？

'''

@ IBOutlet弱var collectionView：UICollectionView！

var model = CardModel()

  //Kepp track of the cards veiwed
  var cardArray = [Card]()


  override func viewDidLoad() {
    super.viewDidLoad()


    //Call the getCards method of the card model

    cardArray = model.getCards()

    collectionView.delegate = self
    collectionView.dataSource = self


}

 // MARK: -UICOlecctionView Protocol Methods

func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {

    return cardArray.count

}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

    // Get a card CardCollectionViewCell object
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CardCell", for: indexPath) as! CardCollectionViewCell

    //Get the card that the collection view is trying to display
    let card = cardArray [indexPath.row]

    //Set the card for the cell
    cell.setCard(card)


    return cell

}


func collectionView( _ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath)

{
    print("Cell is taped: \(indexPath.row)")

   let cell =  collectionView.cellForItem(at: indexPath) as! CardCollectionViewCell


    // Flip the card



    cell.flip()




}

}

我同意@toto。您的大多数代码看起来不错，但我认为您可能会遗漏一些东西。这是我自己的“收藏夹视图”功能的示例：

extension ViewController: UICollectionViewDataSource {
func collectionView(_ collectionView: UICollectionView, 
 numberOfItemsInSection section: Int) -> Int {
    return userDetails.count
}

[似乎您可能只是想念return-I have an extensive Collection View（由Firebase FYI所吸引），对您也有所帮助！祝你好运！
