覆盖UIGestureRecognizer touchesBegan

Question

我有一个主视图和一个SubView

主视图> SubView

我认为主要观点是“窃取”SubView的事件。

例如，当我点击SubView时，只有主视图GestureRecognizer是fire。

下面是我的自定义GestureRecognizer (它拦截每个触摸事件)：

import UIKit
import UIKit.UIGestureRecognizerSubclass

class MainGestureRecognizer: UIGestureRecognizer {
    
    override func touchesBegan(touches: NSSet!, withEvent event: UIEvent!) {
        super.touchesBegan(touches, withEvent: event);
        //nextResponder() ??
        
        state = UIGestureRecognizerState.Began;
    }
 
    override func touchesMoved(touches: NSSet!, withEvent event: UIEvent!) {
        super.touchesMoved(touches, withEvent: event);
        //nextResponder() ??
        
        state = UIGestureRecognizerState.Changed;
    }
 
    override func touchesEnded(touches: NSSet!, withEvent event: UIEvent!) {
        super.touchesEnded(touches, withEvent: event);
        //nextResponder() ??
        
        state = UIGestureRecognizerState.Ended;
    }
 
    override func touchesCancelled(touches: NSSet!, withEvent event: UIEvent!) {
        super.touchesCancelled(touches, withEvent: event);
        //nextResponder() ??
        
        state = UIGestureRecognizerState.Cancelled;
    }
}

也许我应该使用nextResponder，，但我只找到了这样的Obj代码：

self.nextResponder触控贝根:触碰事件:事件； What's the trick to pass an event to the next responder in the responder chain? Is there a way to pass touches through on the iPhone?

所以问题是，我应该怎么做才能让第二个事件( SubView事件)也发生呢？

在Swift中有像nextResponder这样的函数吗？

快跳啊！以下是nextResponder的Swift代码：
