使用其父的xib的UICollectionViewCell子类

import UIKit

class CustomCell: UICollectionViewCell {
    @IBOutlet weak var titleLabel: UILabel!
    @IBOutlet weak var imageView: UIImageView!
    
    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
        self.layer.cornerRadius = 8
        self.layer.masksToBounds = true
    }
    
    func configure(with title: String, image: UIImage) {
        titleLabel.text = title
        imageView.image = image
    }
}

import UIKit

class ViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate {
    @IBOutlet weak var collectionView: UICollectionView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // Register the custom cell
        collectionView.register(UINib(nibName: "CustomCell", bundle: nil), forCellWithReuseIdentifier: "CustomCell")
        
        // Set data source and delegate
        collectionView.dataSource = self
        collectionView.delegate = self
    }
    
    // MARK: - UICollectionViewDataSource
    
    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return 10 // Example number of items
    }
    
    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CustomCell", for: indexPath) as! CustomCell
        
        // Configure the cell with data
        cell.configure(with: "Item \(indexPath.item)", image: UIImage(named: "exampleImage")!)
        
        return cell
    }
}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CustomCell", for: indexPath) as! CustomCell
    
    // Clear previous content to avoid reuse issues
    cell.titleLabel.text = ""
    cell.imageView.image = nil
    
    // Configure the cell with new data
    cell.configure(with: "Item \(indexPath.item)", image: UIImage(named: "exampleImage")!)
