如何在不使用故事板的情况下获取viewcontroller的NibName

class MyViewController: UIViewController {
    init() {
        super.init(nibName: nil, bundle: nil)
        
        let className = NSStringFromClass(type(of: self))
        let nibName = className + ".xib"
        
        // 使用nibName进行后续操作
        print("NibName: \(nibName)")
    }
    
    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}
