ios - 将图像数组添加到 Collection View - swift

Question

我正在编写一个程序，用于拍摄照片并将它们显示在 Collection View 中。

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

下面的函数是 cellForItemAt 这是 cell.imageView.image = image 行发生错误的地方。

给出的错误是:

Value of type 'UICollectionViewCell' has no member 'imageView'

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "collectionCell", for: indexPath) as UICollectionViewCell
    let image = myImages[indexPath.row]
    cell.imageView.image = image
    return cell
}

我的 collectionCell 类声明如下。它通过 Storyboard等连接到 collectionView，所以我不确定为什么会发生错误。

class collectionCell: UICollectionViewCell { 
    @IBOutlet weak var imageView: UIImageView!
}

Answer 1

写类名而不是 UICollectionCell

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
       let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "collectionCell", for: indexPath) as! collectionCell
       let image = myImages[indexPath.row]
       cell.imageView.image = image
       return cell
   }
