我为您创建了这个自定义类（在声明按钮时，编写 Covid19Button 而不是 UIButton 以便使用它）。

class Covid19Button: UIButton {
   //declare here the objects or variables you want in your custom object
    var label: UILabel!
    var image: UIImageView!
    
    override init(frame: CGRect) {
        super.init(frame: frame)
       commonInit()
    }
    
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
     commonInit()
    }
    
    func commonInit(){
//Set your objects' frame and other stuff like colors ecc note that here I set random dimensions. The x should be ok however. You can change them as you prefer 
        label = UILabel(frame: CGRect(x: 20, y: 20, width: 100, height: frame.height-40))
        image = UIImageView(frame: CGRect(x: frame.width-20-image.frame.width, y: 20, width: 50, height: frame.height-40))
        
        addSubview(label)
        addSubview(image)
        
    }
    
}
