ios - swift:更改特定单元格中的图像

Question

我有 collectionView。我想更改特定单元格中的图像。

我使用这段代码:

func collectionView(_ collectionView: UICollectionView, willDisplay cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {

let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! MasterViewCell

    if indexPath.section == 1 && indexPath.row == 5{
        cell.cover.image = UIImage(named: "sfsdf.png")
    }
}

但是图像在所有单元格中都发生了变化。如何解决？

Answer 1

这是因为出队

func collectionView(_ collectionView: UICollectionView, willDisplay cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {

    let myCell = cell as! MasterViewCell

    if indexPath.section == 1 && indexPath.row == 5{
        myCell.cover.image = UIImage(named: "sfsdf.png")
    }
    else {
        myCell.cover.image = UIImage(named: "other.png") // supply other image or access from model array 
    }
}
