向 UILabel 添加手势

Question

我正在尝试向我的UILabel 添加一个点击手势，但在点击标签时无法让它弹出。我看看其他人是怎么做的，从我发现的那些人中，他们一直在一行中声明标签，然后在视图中添加手势确实加载了。是否可以在我的标签声明中添加手势以保持整洁？

let apetureButton: UILabel = {
    let tapLabel = UITapGestureRecognizer(target: self, action: #selector(apetureSelect))
    let text = UILabel() 
    text.isUserInteractionEnabled = true
    text.addGestureRecognizer(tapLabel)
    text.text = "400"  
    return text
}()

@objc func apetureSelect(sender:UITapGestureRecognizer) {
     print("ApetureSelect")
}

你需要一个 lazy 变量才能从闭包内部访问self

lazy var apetureButton: UILabel = { 
   let text = UILabel() 
   let tapLabel = UITapGestureRecognizer(target: self, action: #selector(apetureSelect))
   text.isUserInteractionEnabled = true
   text.addGestureRecognizer(tapLabel)
   text.text = "400" 
   return text
}()
