如何禁用多个手势识别器之一？

Question

我试图禁用我添加到视图中的3个手势识别器中的1个，是否有人知道正确的代码是什么？

这是我到目前为止所拥有的：

// the gesture recognizer i'm trying to disable

    let tap = UITapGestureRecognizer(target: self, action: #selector(self.handleTap(_:)))
    myImageView1.addGestureRecognizer(tap)


// the code to disable it

    let allGRs = [currentView.gestureRecognizers]

    for g in allGRs {

        if let g as? UITapGestureRecognizer {
            g.isEnabled = false
        }

    }

谢谢！

Answer 1

您应该将name属性指定给手势识别器。

tap.name = "myTapGesture"

之后你可以循环使用recozniers，只能禁用你想要的那个。

for aRecognizer in view.gestureRecognizers {
   if let name = aRecognizer.name {
       if name == "myTapGesture" {
           aRecognizer.isEnabled = false
       }
   }
}

希望这可以帮到你！

1. 为UITapGestureRecogniser添加唯一名称

   let tapName = "100" //Any unique name
   func addGestureRecognisers() {
       let view = UIView() // Your view in your context. I just added to test my code
       let tap = UITapGestureRecognizer(target: self, action: action: #selector(self.handleTap(_:)))
       tap.name = tapName 
       view.addGestureRecognizer(tap)
   }

2. 过滤UITapGestureRecognisers，然后按name过滤结果。

   func disableTapGesture(from view: UIView) {
       view.gestureRecognizers?.filter({$0.name == tapName}).first?.isEnabled = false
   }
