如何从Swift中的自定义UIView执行pushViewController？

import UIKit

class CustomView: UIView {
    
    func pushViewController() {
        // 获取父视图控制器
        var parentViewController: UIViewController? = self.next as? UIViewController
        
        // 寻找最近的视图控制器
        while parentViewController != nil && !(parentViewController is UINavigationController) {
            parentViewController = parentViewController!.parent
        }
        
        // 判断是否找到导航控制器
        guard let navigationController = parentViewController as? UINavigationController else {
            return
        }
        
        // 创建目标视图控制器并推入导航栈
        let destinationViewController = UIViewController()
        navigationController.pushViewController(destinationViewController, animated: true)
    }
}
