Ios 等待用户触摸屏幕。敏捷的

发生某些事情后，我会让视图显示一个标签

let myView = UIView(frame: CGRect(x: 100, y: 100, width: 100, height: 100))
let label = UILabel(frame: CGRect(x:0,y:0,width: 100, height: 100))
myView.addSubview(lebel)
self.view.addSubview(myView)
myView.alpha = 0
UIView.animate(withDuration: 0.5, animations: {
        myView.alpha = 1
    })

现在我想让你等到屏幕上出现点击，然后

UIView.animate(withDuration: 0.5, animations: {
            muView.alpha = 0
        }, completion: { (bool) in
            myView.removeFromSuperview()
    })

我怎样才能等到触摸到屏幕？

只需将点击手势添加到视图中即可

在viewDidload

手势

 @IBAction func handleTapGesture(_ recognizer: UITapGestureRecognizer) {

      UIView.animate(withDuration: 0.5, animations: {
            muView.alpha = 0
           }, completion: { (bool) in
            myView.removeFromSuperview()
       })

    }

除了Abdelahad的答案之外，您还应该将let myView声明为一个属性，以便在@IBAction func HandletApsignizer\uRecognitizer:UITapGestureRecognitizer{}中使用它。因此，新代码如下所示：

 @IBAction func handleTapGesture(_ recognizer: UITapGestureRecognizer) {

  UIView.animate(withDuration: 0.5, animations: {
        self.myView.alpha = 0
       }, completion: { (bool) in
        self.myView.removeFromSuperview()
   })
}

---

最后，我在代码中发现了您的小错误。muView是错误的，myView是正确的。

等等什么？您是否需要在等待中明确执行任何操作？否则，点击手势识别器可能会触发…查看如何使用UITapGestureRecognitor。它使您能够监听视图的顶部，并允许您在点击时选择要触发的函数。

 @IBAction func handleTapGesture(_ recognizer: UITapGestureRecognizer) {

  UIView.animate(withDuration: 0.5, animations: {
        self.myView.alpha = 0
       }, completion: { (bool) in
        self.myView.removeFromSuperview()
   })
}
