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

I'm setting up a new project with a UICollectionView that displays an image. I created the ViewController and the CellViewController, just like its supposed to.

我正在设置一个带有显示图像的UICollectionView的新项目。我创建了ViewController和CellViewController,就像它应该的那样。

In the CellViewController the code is the following:

在CellViewController中,代码如下:

import UIKit

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

But in the ViewController when I'm setting up the image it gives me the error. Here's the code:

但是在ViewController中,当我设置图像时,它给了我错误。这是代码:

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


    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier,
                                                      for: indexPath)
    // Configure the cell
    cell.backgroundColor = UIColor.black
    cell.imageView.image = UIImage(named: "pic1")
    return cell;
}

Thanks in advance..

提前致谢..

You should cast your collectionViewCell subclass as your custom one ClubCollectionViewCell.

您应该将collectionViewCell子类强制转换为自定义的ClubCollectionViewCell。

Use guard to check for the type of the cell, do fatalError() if it fails.

使用guard检查单元格的类型,如果失败则执行fatalError()。

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

    guard let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier,
                                                            for: indexPath) as? ClubCollectionViewCell else {
                                                                    fatalError("Wrong cell class dequeued")
    }
        // Configure the cell
        cell.backgroundColor = UIColor.black
        cell.imageView.image = UIImage(named: "pic1")
        return cell
 }
