覆盖UIGestureRecognizer touches开始 [英] Override UIGestureRecognizer touchesBegan

问题描述

我有1个主视图和1个 SubView :

I have 1 Main View and 1 SubView:

主视图>子视图

我认为主视图正在窃取" SubView 中的事件.

I think that the Main View is "stealing" the events from the SubView.

例如，当我点击 SubView 时，只有 Main View GestureRecognizer 被触发.

For example, when I tap on the SubView, only the Main View GestureRecognizer is fire.

这是我的自定义 GestureRecognizer (它会拦截每个触摸事件):

Here is my custom GestureRecognizer (which intercepts every touch event):

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 ，但是我只发现了如下的Obj-C代码:

Maybe I should use nextResponder, but I have only found Obj-C code like:

[self.nextResponder touchesBegan:touches withEvent:event];

[self.nextResponder touchesBegan:touches withEvent:event];

将事件传递给响应者链中的下一个响应者的诀窍是什么?

有没有办法通过触摸通过iPhone?

问题是，我该怎么做才能使第二个事件(SubView事件)也触发?

So the question is, what should I do to make the second event (the SubView Event) fire too?

在Swift中是否有类似 nextResponder 的功能?

Is there a function like nextResponder in Swift?

推荐答案

Ôh！这是 nextResponder 的Swift代码:

Ôh ! Here is the Swift code for nextResponder :
