使用UIGestureRecognizer获取UIview的UIabel文字

Question

我想使用UIGestureRecognizer获取UIview(uiViews)的UILabel(label)的文本值。

但是，在我的代码中出现错误。

请告诉我正确的代码。

func test(){
    let uiViews = uiView.instance()//xib instance
    uiViews.label.text = "Yeah"
    self.addSubview(uiViews)
    uiViews.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(tapped.selected(_:))))
}

@objc func tapped(_ sender: UITapGestureRecognizer) {
    print(sender.label.text) //Value of type 'UITapGestureRecognizer' has no member 'label'
}

//Error
Value of type 'UITapGestureRecognizer' has no member 'label'

Answer 1

发送者是 UITapGestureRecognizer，它有一个名为 view 的属性，它是被点击的视图。使用 (sender.view as? uiView)?.label?.text 与 uiView/label.
