如何禁用多个手势识别器之一？

Question

我正在尝试禁用已添加到视图的 3 个手势识别器中的 1 个，有人知道正确的代码是什么吗？

这是我目前的情况：

// 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

希望对您有所帮助！

为您的 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)
}

过滤UITapGestureRecognisers，然后按name过滤结果。

func disableTapGesture(from view: UIView) {
    view.gestureRecognizers?.filter({[=11=].name == tapName}).first?.isEnabled = false
}

Answer 2

您应该将名称属性分配给您的手势识别器。

tap.name = "myTapGesture"

稍后你可以循环浏览 recozniers，只禁用你想要的那个。

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