Question

我无法让这个工作。当我拉我的头发时，有没有人有任何想法。

import UIKit

private let reuseIdentifier = "CardViewCell"

class GameViewController: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource {

    var collectionData = ["image2", "image2", "image2", "image2", "image2", "image2", "image2", "image2", "image2", "image2", "image2", "image2", "image2", "image2", "image2", "image2"]

    @IBOutlet weak var collectionView: UICollectionView!

    override func viewDidLoad() {
        super.viewDidLoad()
        collectionView.delegate = self
        collectionView.dataSource = self

        // Set up the 4x4 grid
        let width = (view.frame.size.width - 60) / 4
        let layout = collectionView.collectionViewLayout as! UICollectionViewFlowLayout
        layout.itemSize = CGSize(width: width, height: width)
    }

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        collectionView.reloadData()
    }

    // MARK: UICollectionViewDataSource

    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return collectionData.count
    }

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

        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier, for: indexPath) as! CardViewCell

        cell.cardImage.image = UIImage(named: collectionData[indexPath.row])

        return cell
    }

    func collectionView(_ collectionView: UICollectionView, didDeselectItemAt indexPath: IndexPath) {

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

        let selectedImage = collectionData[indexPath.item]

        cell.flipCardAction(selectedImage)
    }
}

试试这个，它会起作用

If V30 = 1 Then
V40 = "Condition met"
ElseIf V30 = 2 Then
V40 = "Condition not met"
Else
V40 = ""
End If

否则如果asp经典中的语句不起作用
