ios - 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 View 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!

您应该将名称属性分配给您的手势识别器。

tap.name = "myTapGesture"

稍后您可以循环浏览 recozniers 并仅禁用您想要的那个。

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