Ios TapGestureRecognitor在另一个类中调用函数并访问第一个类的变量

当我在第一个ViewController中点击UIImageView时，我正在调用另一个类中的函数：

let tapGestureRecognizer = UITapGestureRecognizer(target: secondclass, action: #selector(secondclass.imageTapped(tapGestureRecognizer:)))

在第二节课中，我需要从第一个ViewController访问一些变量

如何获得对第一个ViewController的引用以实现此目的

二等舱：

@objc func imageTapped(tapGestureRecognizer: UITapGestureRecognizer)
{

    let tappedImage = tapGestureRecognizer.view as! UIImageView

    //reference to first ViewController needed
}

---

然后在第二个VC中添加一个委托

weak var delegate:FirstVC?

并在第一个vc中进行配置

secondclass.delegate = self

---

尝试在ViewController之间使用委托

protocol ImageDelegate: class {
    func didTapped()
}

class FirstVC: UIViewController, ImageDelegate {
    let imageView: UIImageView!
    let secondVC: SecondVC!


    override func viewDidLoad() {
        super.viewDidLoad()
        secondVC.imageDelegate = self

    }


}
class SecondVC: UIViewController {
    weak var imageDelegate: ImageDelegate? 

    override func viewDidLoad() {
        super.viewDidLoad()
        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleTap))
    }

    @objc func handleTap() {
        imageDelegate?.didTapped()
    } 
}
