ios – 如何在touchesBegan方法中发生双击时防止单击被调用

import SpriteKit

class GameScene: SKScene {

    var recognizers:[UIGestureRecognizer] = []

    override func didMove(to view: SKView) {

        // Get label node from scene and store it for use later


        let single = UITapGestureRecognizer(target: self,action: #SELEctor(GameScene.singleTapHandler(recognizer:)))
        view.addGestureRecognizer(singlE)
        single.numberOfTapsrequired = 1
        recognizers.append(singlE)

        let double = UITapGestureRecognizer(target: self,action: #SELEctor(GameScene.doubleTapHandler(recognizer:)))
        view.addGestureRecognizer(doublE)
        double.numberOfTapsrequired = 2
        recognizers.append(doublE)

        single.require(toFail: doublE)

    }

    override func willMove(from view: SKView) {
        super.willMove(from: view)

        for recognizer in recognizers {
            self.view?.removeGestureRecognizer(recognizer)
        }
        recognizers.removeAll()
    }

    func singleTapHandler(recognizer:UITapGestureRecognizer){

        print("Single tap detected")
    }

    func doubleTapHandler(recognizer:UITapGestureRecognizer){
        print("Double tap detected")
    }

}

当然,在ViewController上调用一些方法可以通过几种方式完成(例如委托)……但是,根据你的评论,我认为处理当前场景中的点击是你想要实现的.

编辑：

要回答评论中的问题…您可以通过在视图中查找触摸位置,将其转​​换为场景中的位置以及抓取该位置处的节点来获取触摸的节点：

func singleTapHandler(recognizer:UITapGestureRecognizer){

        print("Single tap detected")

        let LOCATIOnInView = recognizer.LOCATIOn(in: self.view)

        let LOCATIOnInScene = self.convertPoint(fromView: LOCATIOnInView)

        print(LOCATIOnInScenE)

       let node = atPoint(LOCATIOnInScenE)

        if let nodename = node.name {
            //do stuff
        }

        //or

        if let sprite = node as? SKSpriteNode {
            // node is an SKSpriteNode
        }
    }
