这里有一个例子

import UIKit

class MusicImageCell: UITableViewCell {
    private let imageView = UIImageView()
    private let ribbonView = RibbonView()
    
    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        
        // Configure and add the image view
        // ...
        
        // Configure and add the ribbon view
        ribbonView.backgroundColor = UIColor.red
        contentView.addSubview(ribbonView)
    }
    
    override func layoutSubviews() {
        super.layoutSubviews()
        
        // Position the ribbon view at the top right corner
        let ribbonSize = CGSize(width: 60, height: 30) // Adjust the size as needed
        let ribbonOrigin = CGPoint(x: imageView.bounds.width - ribbonSize.width, y: 0)
        ribbonView.frame = CGRect(origin: ribbonOrigin, size: ribbonSize)
    }
    
    // Other methods and configurations for your music image cell
    // ...
}

class RibbonView: UIView {
    override func draw(_ rect: CGRect) {
        // Customize the appearance of the ribbon using Core Graphics or UIBezierPath
        let path = UIBezierPath()
        
        // Add the ribbon shape to the path
        // ...
        
        // Fill the path with the desired color
        UIColor.red.setFill()
        path.fill()
    }
}

在本例中，MusicImageCell是一个自定义表格视图单元格子类，它包含一个图像视图（imageView）和一个功能区视图（ribbonView）。layoutSubviews()方法被重写，以将功能区视图定位在图像视图的右上角。RibbonView是一个自定义UIView子类，它使用draw(_ rect: CGRect)通过Core Graphics或UIBezierPath自定义功能区的外观。
